+ \class QAbstractEventDispatcher
+ \brief The QAbstractEventDispatcher class provides an interface to manage Qt's event queue.
+
+ \ingroup application
+ \ingroup events
+
+ An event dispatcher receives events from the window system and other
+ sources. It then sends them to the QCoreApplication or QApplication
+ instance for processing and delivery. QAbstractEventDispatcher provides
+ fine-grained control over event delivery.
+
+ For simple control of event processing use
+ QCoreApplication::processEvents().
+
+ For finer control of the application's event loop, call
+ instance() and call functions on the QAbstractEventDispatcher
+ object that is returned. If you want to use your own instance of
+ QAbstractEventDispatcher or of a QAbstractEventDispatcher
+ subclass, you must create your instance \e before you create the
+ QApplication object.
+
+ The main event loop is started by calling
+ QCoreApplication::exec(), and stopped by calling
+ QCoreApplication::exit(). Local event loops can be created using
+ QEventLoop.
+
+ Programs that perform long operations can call processEvents()
+ with a bitwise OR combination of various QEventLoop::ProcessEventsFlag
+ values to control which events should be delivered.
+
+ QAbstractEventDispatcher also allows the integration of an
+ external event loop with the Qt event loop. For example, the
+ \l{Qt Solutions}{Motif Extension Qt Solution} includes a
+ reimplementation of QAbstractEventDispatcher that merges Qt and
+ Motif events together.

+
+ \ingroup model-view
+
+ A QPersistentModelIndex is a model index that can be stored by an
+ application, and later used to access information in a model.
+ Unlike the QModelIndex class, it is safe to store a
+ QPersistentModelIndex since the model will ensure that references
+ to items will continue to be valid as long as they can be accessed
+ by the model.
+
+ It is good practice to check that persistent model indexes are valid
+ before using them.

+ \class QModelIndex
+
+ \brief The QModelIndex class is used to locate data in a data model.
+
+ \ingroup model-view
+ \mainclass
+
+ This class is used as an index into item models derived from
+ QAbstractItemModel. The index is used by item views, delegates, and
+ selection models to locate an item in the model.
+
+ New QModelIndex objects are created by the model using the
+ QAbstractItemModel::createIndex() function. An \e invalid model index
+ can be constructed with the QModelIndex constructor. Invalid indexes are
+ often used as parent indexes when referring to top-level items in a model.
+
+ Model indexes refer to items in models, and contain all the information
+ required to specify their locations in those models. Each index is located
+ in a given row and column, and may have a parent index; use row(), column(),
+ and parent() to obtain this information. Each top-level item in a model is
+ represented by a model index that does not have a parent index - in this
+ case, parent() will return an invalid model index, equivalent to an index
+ constructed with the zero argument form of the QModelIndex() constructor.
+
+ To obtain a model index that refers to an existing item in a model, call
+ QAbstractItemModel::index() with the required row and column
+ values, and the model index of the parent. When referring to
+ top-level items in a model, supply QModelIndex() as the parent index.
+
+ The model() function returns the model that the index references as a
+ QAbstractItemModel.
+ The child() function is used to examine the items held beneath the index
+ in the model.
+ The sibling() function allows you to traverse items in the model on the
+ same level as the index.
+
+ \note Model indexes should be used immediately and then discarded. You
+ should not rely on indexes to remain valid after calling model functions
+ that change the structure of the model or delete items. If you need to
+ keep a model index over time use a QPersistentModelIndex.

+ \class QAbstractItemModel
+
+ \brief The QAbstractItemModel class provides the abstract interface for
+ item model classes.
+
+ \ingroup model-view
+ \mainclass
+
+ The QAbstractItemModel class defines the standard interface that item
+ models must use to be able to interoperate with other components in the
+ model/view architecture. It is not supposed to be instantiated directly.
+ Instead, you should subclass it to create new models.
+
+ The QAbstractItemModel class is one of the \l{Model/View Classes}
+ and is part of Qt's \l{Model/View Programming}{model/view framework}.
+
+ If you need a model to use with a QListView or a QTableView, you should
+ consider subclassing QAbstractListModel or QAbstractTableModel instead of
+ this class.
+
+ The underlying data model is exposed to views and delegates as a hierarchy
+ of tables. If you do not make use of the hierarchy, then the model is a
+ simple table of rows and columns. Each item has a unique index specified by
+ a QModelIndex.
+
+ \img modelindex-no-parent.png
+
+ Every item of data that can be accessed via a model has an associated model
+ index. You can obtain this model index using the index() function. Each
+ index may have a sibling() index; child items have a parent() index.
+
+ Each item has a number of data elements associated with it and they can be
+ retrieved by specifying a role (see \l Qt::ItemDataRole) to the model's
+ data() function. Data for all available roles can be obtained at the same
+ time using the itemData() function.
+
+ Data for each role is set using a particular \l Qt::ItemDataRole. Data for
+ individual roles are set individually with setData(), or they can be set
+ for all roles with setItemData().
+
+ Items can be queried with flags() (see \l Qt::ItemFlag) to see if they can
+ be selected, dragged, or manipulated in other ways.
+
+ If an item has child objects, hasChildren() returns true for the
+ corresponding index.
+
+ The model has a rowCount() and a columnCount() for each level of the
+ hierarchy. Rows and columns can be inserted and removed with insertRows(),
+ insertColumns(), removeRows(), and removeColumns().
+
+ The model emits signals to indicate changes. For example, dataChanged() is
+ emitted whenever items of data made available by the model are changed.
+ Changes to the headers supplied by the model cause headerDataChanged() to
+ be emitted. If the structure of the underlying data changes, the model can
+ emit layoutChanged() to indicate to any attached views that they should
+ redisplay any items shown, taking the new structure into account.
+
+ The items available through the model can be searched for particular data
+ using the match() function.
+
+ To sort the model, you can use sort().
+
+
+ \section1 Subclassing
+
+ \note Some general guidelines for subclassing models are available in the
+ \l{Model Subclassing Reference}.
+
+ When subclassing QAbstractItemModel, at the very least you must implement
+ index(), parent(), rowCount(), columnCount(), and data(). These functions
+ are used in all read-only models, and form the basis of editable models.
+
+ You can also reimplement hasChildren() to provide special behavior for
+ models where the implementation of rowCount() is expensive. This makes it
+ possible for models to restrict the amount of data requested by views, and
+ can be used as a way to implement lazy population of model data.
+
+ To enable editing in your model, you must also implement setData(), and
+ reimplement flags() to ensure that \c ItemIsEditable is returned. You can
+ also reimplement headerData() and setHeaderData() to control the way the
+ headers for your model are presented.
+
+ The dataChanged() and headerDataChanged() signals must be emitted
+ explicitly when reimplementing the setData() and setHeaderData() functions,
+ respectively.
+
+ Custom models need to create model indexes for other components to use. To
+ do this, call createIndex() with suitable row and column numbers for the
+ item, and an identifier for it, either as a pointer or as an integer value.
+ The combination of these values must be unique for each item. Custom models
+ typically use these unique identifiers in other reimplemented functions to
+ retrieve item data and access information about the item's parents and
+ children. See the \l{Simple Tree Model Example} for more information about
+ unique identifiers.
+
+ It is not necessary to support every role defined in Qt::ItemDataRole.
+ Depending on the type of data contained within a model, it may only be
+ useful to implement the data() function to return valid information for
+ some of the more common roles. Most models provide at least a textual
+ representation of item data for the Qt::DisplayRole, and well-behaved
+ models should also provide valid information for the Qt::ToolTipRole and
+ Qt::WhatsThisRole. Supporting these roles enables models to be used with
+ standard Qt views. However, for some models that handle highly-specialized
+ data, it may be appropriate to provide data only for user-defined roles.
+
+ Models that provide interfaces to resizable data structures can provide
+ implementations of insertRows(), removeRows(), insertColumns(),and
+ removeColumns(). When implementing these functions, it is important to
+ notify any connected views about changes to the model's dimensions both
+ \e before and \e after they occur:
+
+ \list
+ \o An insertRows() implementation must call beginInsertRows() \e before
+ inserting new rows into the data structure, and endInsertRows()
+ \e{immediately afterwards}.
+ \o An insertColumns() implementation must call beginInsertColumns()
+ \e before inserting new columns into the data structure, and
+ endInsertColumns() \e{immediately afterwards}.
+ \o A removeRows() implementation must call beginRemoveRows() \e before
+ the rows are removed from the data structure, and endRemoveRows()
+ \e{immediately afterwards}.
+ \o A removeColumns() implementation must call beginRemoveColumns()
+ \e before the columns are removed from the data structure, and
+ endRemoveColumns() \e{immediately afterwards}.
+ \endlist
+
+ The \e private signals that these functions emit give attached components
+ the chance to take action before any data becomes unavailable. The
+ encapsulation of the insert and remove operations with these begin and end
+ functions also enables the model to manage \l{QPersistentModelIndex}
+ {persistent model indexes} correctly. \bold{If you want selections to be
+ handled properly, you must ensure that you call these functions.} If you
+ insert or remove an item with children, you do not need to call these
+ functions for the child items. In other words, the parent item will take
+ care of its child items.
+
+ To create models that populate incrementally, you can reimplement
+ fetchMore() and canFetchMore(). If the reimplementation of fetchMore() adds
+ rows to the model, \l{QAbstractItemModel::}{beginInsertRows()} and
+ \l{QAbstractItemModel::}{endInsertRows()} must be called.

+
+ \ingroup model-view
+
+ QAbstractTableModel provides a standard interface for models that represent
+ their data as a two-dimensional array of items. It is not used directly,
+ but must be subclassed.
+
+ Since the model provides a more specialized interface than
+ QAbstractItemModel, it is not suitable for use with tree views, although
+ it can be used to provide data to a QListView. If you need to represent
+ a simple list of items, and only need a model to contain a single column
+ of data, subclassing the QAbstractListModel may be more appropriate.
+
+ The rowCount() and columnCount() functions return the dimensions of the
+ table. To retrieve a model index corresponding to an item in the model, use
+ index() and provide only the row and column numbers.
+
+ \section1 Subclassing
+
+ \bold{Note:} Some general guidelines for subclassing models are
+ available in the \l{Model Subclassing Reference}.
+
+ When subclassing QAbstractTableModel, you must implement rowCount(),
+ columnCount(), and data(). Default implementations of the index() and
+ parent() functions are provided by QAbstractTableModel.
+ Well behaved models will also implement headerData().
+
+ Editable models need to implement setData(), and implement flags() to
+ return a value containing
+ \l{Qt::ItemFlags}{Qt::ItemIsEditable}.
+
+ Models that provide interfaces to resizable data structures can
+ provide implementations of insertRows(), removeRows(), insertColumns(),
+ and removeColumns(). When implementing these functions, it is
+ important to call the appropriate functions so that all connected views
+ are aware of any changes:
+
+ \list
+ \o An insertRows() implementation must call beginInsertRows()
+ \e before inserting new rows into the data structure, and it must
+ call endInsertRows() \e{immediately afterwards}.
+ \o An insertColumns() implementation must call beginInsertColumns()
+ \e before inserting new columns into the data structure, and it must
+ call endInsertColumns() \e{immediately afterwards}.
+ \o A removeRows() implementation must call beginRemoveRows()
+ \e before the rows are removed from the data structure, and it must
+ call endRemoveRows() \e{immediately afterwards}.
+ \o A removeColumns() implementation must call beginRemoveColumns()

+ \class QAbstractListModel
+ \brief The QAbstractListModel class provides an abstract model that can be

+
+ \ingroup model-view
+
+ QAbstractListModel provides a standard interface for models that represent
+ their data as a simple non-hierarchical sequence of items. It is not used
+ directly, but must be subclassed.
+
+ Since the model provides a more specialized interface than
+ QAbstractItemModel, it is not suitable for use with tree views; you will
+ need to subclass QAbstractItemModel if you want to provide a model for
+ that purpose. If you need to use a number of list models to manage data,
+ it may be more appropriate to subclass QAbstractTableModel class instead.
+
+ Simple models can be created by subclassing this class and implementing
+ the minimum number of required functions. For example, we could implement
+ a simple read-only QStringList-based model that provides a list of strings
+ to a QListView widget. In such a case, we only need to implement the
+ rowCount() function to return the number of items in the list, and the
+ data() function to retrieve items from the list.
+
+ Since the model represents a one-dimensional structure, the rowCount()
+ function returns the total number of items in the model. The columnCount()
+ function is implemented for interoperability with all kinds of views, but
+ by default informs views that the model contains only one column.

+ \class QBasicTimer
+ \brief The QBasicTimer class provides timer events for objects.
+
+ \ingroup time
+ \ingroup events
+
+ This is a fast, lightweight, and low-level class used by Qt
+ internally. We recommend using the higher-level QTimer class
+ rather than this class if you want to use timers in your
+ applications.
+
+ To use this class, create a QBasicTimer, and call its start()
+ function with a timeout interval and with a pointer to a QObject
+ subclass. When the timer times out it will send a timer event to
+ the QObject subclass. The timer can be stopped at any time using
+ stop(). isActive() returns true for a timer that is running;
+ i.e. it has been started, has not reached the timeout time, and
+ has not been stopped. The timer's ID can be retrieved using
+ timerId().
+
+ The \l{widgets/wiggly}{Wiggly} example uses QBasicTimer to repaint
+ a widget at regular intervals.

+ \class QCoreApplication
+ \brief The QCoreApplication class provides an event loop for console Qt
+ applications.
+
+ \ingroup application
+ \mainclass
+
+ This class is used by non-GUI applications to provide their event
+ loop. For non-GUI application that uses Qt, there should be exactly
+ one QCoreApplication object. For GUI applications, see
+ QApplication.
+
+ QCoreApplication contains the main event loop, where all events
+ from the operating system (e.g., timer and network events) and
+ other sources are processed and dispatched. It also handles the
+ application's initialization and finalization, as well as
+ system-wide and application-wide settings.
+
+ The command line arguments which QCoreApplication's constructor
+ should be called with are accessible using arguments(). The
+ event loop is started with a call to exec(). Long running
+ operations can call processEvents() to keep the application
+ responsive.
+
+ Some Qt classes, such as QString, can be used without a
+ QCoreApplication object. However, in general, we recommend that
+ you create a QCoreApplication or a QApplication object in your \c
+ main() function as early as possible. The application will enter
+ the event loop when exec() is called. exit() will not return
+ until the event loop exits, e.g., when quit() is called.
+
+ An application has an applicationDirPath() and an
+ applicationFilePath(). Translation files can be added or removed
+ using installTranslator() and removeTranslator(). Application
+ strings can be translated using translate(). The QObject::tr()
+ and QObject::trUtf8() functions are implemented in terms of
+ translate().
+
+ The class provides a quit() slot and an aboutToQuit() signal.
+
+ Several static convenience functions are also provided. The
+ QCoreApplication object is available from instance(). Events can
+ be sent or posted using sendEvent(), postEvent(), and
+ sendPostedEvents(). Pending events can be removed with
+ removePostedEvents() or flushed with flush(). Library paths (see
+ QLibrary) can be retrieved with libraryPaths() and manipulated by
+ setLibraryPaths(), addLibraryPath(), and removeLibraryPath().

+ \l{QWidget::isEnabled()}{disabled widgets}. Note that application
+ event filters are only called for objects that live in the main

+ \class QEvent
+ \brief The QEvent class is the base class of all
+ event classes. Event objects contain event parameters.
+
+ \ingroup events
+ \ingroup environment
+
+ Qt's main event loop (QCoreApplication::exec()) fetches native
+ window system events from the event queue, translates them into
+ QEvents, and sends the translated events to \l{QObject}s.
+
+ In general, events come from the underlying window system
+ (spontaneous() returns true), but it is also possible to manually
+ send events using QCoreApplication::sendEvent() and
+ QCoreApplication::postEvent() (spontaneous() returns false).
+
+ QObjects receive events by having their QObject::event() function
+ called. The function can be reimplemented in subclasses to
+ customize event handling and add additional event types;
+ QWidget::event() is a notable example. By default, events are
+ dispatched to event handlers like QObject::timerEvent() and
+ QWidget::mouseMoveEvent(). QObject::installEventFilter() allows an
+ object to intercept events destined for another object.
+
+ The basic QEvent contains only an event type parameter and an
+ "accept" flag. The accept flag set with accept(), and cleared
+ with ignore(). It is set by default, but don't rely on this as
+ subclasses may choose to clear it in their constructor.
+
+ Subclasses of QEvent contain additional parameters that describe
+ the particular event.

+/*!
+ \class QMetaObject
+
+ \brief The QMetaObject class contains meta-information about Qt
+ objects.
+
+ \ingroup objectmodel
+
+ The Qt \l{Meta-Object System} in Qt is responsible for the
+ signals and slots inter-object communication mechanism, runtime
+ type information, and the Qt property system. A single
+ QMetaObject instance is created for each QObject subclass that is
+ used in an application, and this instance stores all the
+ meta-information for the QObject subclass. This object is
+ available as QObject::metaObject().
+
+ This class is not normally required for application programming,
+ but it is useful if you write meta-applications, such as scripting
+ engines or GUI builders.
+
+ The functions you are most likely to find useful are these:
+ \list
+ \o className() returns the name of a class.
+ \o superClass() returns the superclass's meta-object.
+ \o method() and methodCount() provide information
+ about a class's meta-methods (signals, slots and other
+ \l{Q_INVOKABLE}{invokable} member functions).
+ \o enumerator() and enumeratorCount() and provide information about
+ a class's enumerators.
+ \o propertyCount() and property() provide information about a
+ class's properties.
+ \o constructor() and constructorCount() provide information
+ about a class's meta-constructors.
+ \endlist
+
+ The index functions indexOfConstructor(), indexOfMethod(),
+ indexOfEnumerator(), and indexOfProperty() map names of constructors,
+ member functions, enumerators, or properties to indexes in the
+ meta-object. For example, Qt uses indexOfMethod() internally when you
+ connect a signal to a slot.
+
+ Classes can also have a list of \e{name}--\e{value} pairs of
+ additional class information, stored in QMetaClassInfo objects.
+ The number of pairs is returned by classInfoCount(), single pairs
+ are returned by classInfo(), and you can search for pairs with
+ indexOfClassInfo().

+ \macro Q_DECLARE_METATYPE(Type)
+ \relates QMetaType
+
+ This macro makes the type \a Type known to QMetaType as long as it
+ provides a public default constructor, a public copy constructor and
+ a public destructor.
+ It is needed to use the type \a Type as a custom type in QVariant.
+
+ Ideally, this macro should be placed below the declaration of
+ the class or struct. If that is not possible, it can be put in
+ a private header file which has to be included every time that
+ type is used in a QVariant.
+
+ Adding a Q_DECLARE_METATYPE() makes the type known to all template
+ based functions, including QVariant. Note that if you intend to
+ use the type in \e queued signal and slot connections or in
+ QObject's property system, you also have to call
+ qRegisterMetaType() since the names are resolved at runtime.
+
+ This example shows a typical use case of Q_DECLARE_METATYPE():
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qmetatype.cpp 0
+
+ If \c MyStruct is in a namespace, the Q_DECLARE_METATYPE() macro
+ has to be outside the namespace:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qmetatype.cpp 1
+
+ Since \c{MyStruct} is now known to QMetaType, it can be used in QVariant:

+ \class QMetaType
+ \brief The QMetaType class manages named types in the meta-object system.
+
+ \ingroup objectmodel
+ \threadsafe
+
+ The class is used as a helper to marshall types in QVariant and
+ in queued signals and slots connections. It associates a type
+ name to a type so that it can be created and destructed
+ dynamically at run-time. Declare new types with Q_DECLARE_METATYPE()
+ to make them available to QVariant and other template-based functions.
+ Call qRegisterMetaType() to make type available to non-template based
+ functions, such as the queued signal and slot connections.
+
+ Any class or struct that has a public default
+ constructor, a public copy constructor, and a public destructor
+ can be registered.
+
+ The following code allocates and destructs an instance of
+ \c{MyClass}:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qmetatype.cpp 3
+
+ If we want the stream operators \c operator<<() and \c
+ operator>>() to work on QVariant objects that store custom types,
+ the custom type must provide \c operator<<() and \c operator>>()
+ operators.

+ \class QMimeData
+ \brief The QMimeData class provides a container for data that records information
+ about its MIME type.
+
+ QMimeData is used to describe information that can be stored in
+ the \l{QClipboard}{clipboard}, and transferred via the \l{drag
+ and drop} mechanism. QMimeData objects associate the data that
+ they hold with the corresponding MIME types to ensure that
+ information can be safely transferred between applications, and
+ copied around within the same application.
+
+ QMimeData objects are usually created using \c new and supplied
+ to QDrag or QClipboard objects. This is to enable Qt to manage
+ the memory that they use.
+
+ A single QMimeData object can store the same data using several
+ different formats at the same time. The formats() function
+ returns a list of the available formats in order of preference.
+ The data() function returns the raw data associated with a MIME
+ type, and setData() allows you to set the data for a MIME type.
+
+ For the most common MIME types, QMimeData provides convenience
+ functions to access the data:
+
+ \table
+ \header \o Tester \o Getter \o Setter \o MIME Types
+ \row \o hasText() \o text() \o setText() \o \c text/plain
+ \row \o hasHtml() \o html() \o setHtml() \o \c text/html
+ \row \o hasUrls() \o urls() \o setUrls() \o \c text/uri-list
+ \row \o hasImage() \o imageData() \o setImageData() \o \c image/ *
+ \row \o hasColor() \o colorData() \o setColorData() \o \c application/x-color
+ \endtable
+
+ For example, if your write a widget that accepts URL drags, you
+ would end up writing code like this:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qmimedata.cpp 0
+
+ There are three approaches for storing custom data in a QMimeData
+ object:
+
+ \list 1
+ \o Custom data can be stored directly in a QMimeData object as a
+ QByteArray using setData(). For example:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qmimedata.cpp 1
+
+ \o We can subclass QMimeData and reimplement hasFormat(),
+ formats(), and retrieveData().
+
+ \o If the drag and drop operation occurs withing a single
+ application, we can subclass QMimeData and add extra data in
+ it, and use a qobject_cast() in the receiver's drop event
+ handler. For example:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qmimedata.cpp 2
+ \endlist
+
+ \section1 Platform-Specific MIME Types
+
+ On Windows, formats() will also return custom formats available
+ in the MIME data, using the \c{x-qt-windows-mime} subtype to
+ indicate that they represent data in non-standard formats.
+ The formats will take the following form:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qmimedata.cpp 3
+
+ The following are examples of custom MIME types:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qmimedata.cpp 4
+
+ The \c value declaration of each format describes the way in which the
+ data is encoded.
+
+ On Windows, the MIME format does not always map directly to the
+ clipboard formats. Qt provides QWindowsMime to map clipboard
+ formats to open-standard MIME formats. Similarly, the
+ QMacPasteboardMime maps MIME to Mac flavors.

+ \class QObject
+ \brief The QObject class is the base class of all Qt objects.
+
+ \ingroup objectmodel
+ \mainclass
+ \reentrant
+
+ QObject is the heart of the \l{Qt object model}. The central
+ feature in this model is a very powerful mechanism for seamless
+ object communication called \l{signals and slots}. You can
+ connect a signal to a slot with connect() and destroy the
+ connection with disconnect(). To avoid never ending notification
+ loops you can temporarily block signals with blockSignals(). The
+ protected functions connectNotify() and disconnectNotify() make
+ it possible to track connections.
+
+ QObjects organize themselves in object trees. When you create a
+ QObject with another object as parent, the object will
+ automatically add itself to the parent's children() list. The
+ parent takes ownership of the object i.e. it will automatically
+ delete its children in its destructor. You can look for an object
+ by name and optionally type using findChild() or findChildren().
+
+ Every object has an objectName() and its class name can be found
+ via the corresponding metaObject() (see QMetaObject::className()).
+ You can determine whether the object's class inherits another
+ class in the QObject inheritance hierarchy by using the
+ inherits() function.
+
+ When an object is deleted, it emits a destroyed() signal. You can
+ catch this signal to avoid dangling references to QObjects.
+
+ QObjects can receive events through event() and filter the events
+ of other objects. See installEventFilter() and eventFilter() for
+ details. A convenience handler, childEvent(), can be reimplemented
+ to catch child events.
+
+ Events are delivered in the thread in which the object was
+ created; see \l{Thread Support in Qt} and thread() for details.
+ Note that event processing is not done at all for QObjects with no
+ thread affinity (thread() returns zero). Use the moveToThread()
+ function to change the thread affinity for an object and its
+ children (the object cannot be moved if it has a parent).
+
+ Last but not least, QObject provides the basic timer support in
+ Qt; see QTimer for high-level support for timers.
+
+ Notice that the Q_OBJECT macro is mandatory for any object that
+ implements signals, slots or properties. You also need to run the
+ \l{moc}{Meta Object Compiler} on the source file. We strongly
+ recommend the use of this macro in all subclasses of QObject
+ regardless of whether or not they actually use signals, slots and
+ properties, since failure to do so may lead certain functions to
+ exhibit strange behavior.
+
+ All Qt widgets inherit QObject. The convenience function
+ isWidgetType() returns whether an object is actually a widget. It
+ is much faster than
+ \l{qobject_cast()}{qobject_cast}<QWidget *>(\e{obj}) or
+ \e{obj}->\l{inherits()}{inherits}("QWidget").
+
+ Some QObject functions, e.g. children(), return a QObjectList.
+ QObjectList is a typedef for QList<QObject *>.
+
+ \target No copy constructor
+ \section1 No copy constructor or assignment operator
+
+ QObject has neither a copy constructor nor an assignment operator.
+ This is by design. Actually, they are declared, but in a
+ \c{private} section with the macro Q_DISABLE_COPY(). In fact, all
+ Qt classes derived from QObject (direct or indirect) use this
+ macro to declare their copy constructor and assignment operator to
+ be private. The reasoning is found in the discussion on
+ \l{Identity vs Value} {Identity vs Value} on the \l{Qt Object
+ Model} page.
+
+ The main consequence is that you should use pointers to QObject
+ (or to your QObject subclass) where you might otherwise be tempted
+ to use your QObject subclass as a value. For example, without a
+ copy constructor, you can't use a subclass of QObject as the value
+ to be stored in one of the container classes. You must store
+ pointers.
+
+ \section2 Auto-Connection
+
+ Qt's meta-object system provides a mechanism to automatically connect
+ signals and slots between QObject subclasses and their children. As long
+ as objects are defined with suitable object names, and slots follow a
+ simple naming convention, this connection can be performed at run-time
+ by the QMetaObject::connectSlotsByName() function.
+
+ \l uic generates code that invokes this function to enable
+ auto-connection to be performed between widgets on forms created
+ with \QD. More information about using auto-connection with \QD is
+ given in the \l{Using a Designer .ui File in Your Application} section of
+ the \QD manual.
+
+ \section2 Dynamic Properties
+
+ From Qt 4.2, dynamic properties can be added to and removed from QObject
+ instances at run-time. Dynamic properties do not need to be declared at
+ compile-time, yet they provide the same advantages as static properties
+ and are manipulated using the same API - using property() to read them
+ and setProperty() to write them.
+
+ From Qt 4.3, dynamic properties are supported by
+ \l{Qt Designer's Widget Editing Mode#The Property Editor}{Qt Designer},
+ and both standard Qt widgets and user-created forms can be given dynamic
+ properties.

+ \reentrant
+
+ Returns a translated version of \a sourceText, optionally based on a

+ otherwise returns \a sourceText itself if no appropriate translated string
+ is available.
+
+ See the sections below on Disambiguation and Handling Plurals for more
+ information about the optional \a disambiguation and \a n parameters.
+
+ QObject and its subclasses obtain translated strings from any translator
+ objects that have been installed on the application object; see the
+ QTranslator documentation for details about this mechanism.
+
+ A translatable string is referenced by its translation context;
+ this is the name of the QObject subclass whose tr() function is invoked,
+ as in the following example:
+
+ \snippet mainwindows/sdi/mainwindow.cpp implicit tr context
+ \dots
+
+ Here, the context is \c MainWindow because it is the \c MainWindow::tr()
+ function that is invoked. Translation contexts can be given explicitly
+ by fully qualifying the call to tr(); for example:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qobject.cpp explicit tr context
+
+ This call obtains the translated text for "Page up" from the \c QScrollBar
+ context.
+
+ \section1 Defining Translation Contexts
+
+ The translation context for QObject and each QObject subclass is the
+ class name itself. Developers subclassing QObject must use the
+ Q_OBJECT macro in their class definition to override the translation
+ context. This macro sets the context to the name of the subclass.
+
+ If Q_OBJECT is not used in a class definition, the context will be
+ inherited from the base class. For example, since all QObject-based
+ classes in Qt provide a context, a new QWidget subclass defined without
+ a Q_OBJECT macro will use the "QWidget" context if its tr() function
+ is invoked.
+
+ \section1 Translator Comments
+
+ Developers can include information about each translatable string to
+ help translators with the translation process. These are extracted
+ when \l lupdate is used to process the source files. The recommended
+ way to add comments is to annotate the tr() calls in your code with
+ comments of the form:
+
+ \tt{//: ...}
+
+ or
+
+ \tt{/*: ... \starslash}
+
+ Examples:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qobject.cpp 40
+
+ In these examples, the comments will be associated with the strings
+ passed to tr() in the context of each call.
+
+ \section1 Disambiguation
+
+ If the same \a sourceText is used in different roles within the
+ same context, an additional identifying string may be passed in
+ \a disambiguation (0 by default). In Qt 4.4 and earlier, this was
+ the preferred way to pass comments to translators.
+
+ Example:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qobject.cpp 17
+
+ \section1 Character Encodings
+
+ You can set the encoding for \a sourceText by calling QTextCodec::setCodecForTr().
+ By default \a sourceText is assumed to be in Latin-1 encoding.
+
+ \section1 Handling Plurals
+
+ If \a n >= 0, all occurrences of \c %n in the resulting string
+ are replaced with a decimal representation of \a n. In addition,
+ depending on \a n's value, the translation text may vary.
+
+ Example:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qobject.cpp 18
+
+ The table below shows what string is returned depending on the
+ active translation:
+
+ \table
+ \header \o \o{3,1} Active Translation
+ \header \o \a n \o No Translation \o French \o English
+ \row \o 0 \o "0 message(s) saved" \o "0 message sauvegard\unicode{0xE9}" \o "0 message\bold{s} saved"
+ \row \o 1 \o "1 message(s) saved" \o "1 message sauvegard\unicode{0xE9}" \o "1 message saved"
+ \row \o 2 \o "2 message(s) saved" \o "2 message\bold{s} sauvegard\unicode{0xE9}\bold{s}" \o "2 message\bold{s} saved"
+ \row \o 37 \o "37 message(s) saved" \o "37 message\bold{s} sauvegard\unicode{0xE9}\bold{s}" \o "37 message\bold{s} saved"
+ \endtable
+
+ This idiom is more flexible than the traditional approach; e.g.,
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qobject.cpp 19
+
+ because it also works with target languages that have several
+ plural forms (e.g., Irish has a special "dual" form that should
+ be used when \c n is 2), and it handles the \e n == 0 case
+ correctly for languages such as French that require the singular.
+ See the \l{Qt Linguist Manual} for details.
+
+ Instead of \c %n, you can use \c %Ln to produce a localized
+ representation of \a n. The conversion uses the default locale,
+ set using QLocale::setDefault(). (If no default locale was
+ specified, the "C" locale is used.)

+ Creates a connection of the given \a type from the \a signal in

+ Returns true if the connection succeeds; otherwise returns false.
+
+ You must use the \c SIGNAL() and \c SLOT() macros when specifying
+ the \a signal and the \a method, for example:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qobject.cpp 22
+
+ This example ensures that the label always displays the current

+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qobject.cpp 23
+
+ A signal can also be connected to another signal:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qobject.cpp 24
+
+ In this example, the \c MyWidget constructor relays a signal from
+ a private member variable, and makes it available under a name
+ that relates to \c MyWidget.
+
+ A signal can be connected to many slots and signals. Many signals
+ can be connected to one slot.
+
+ If a signal is connected to several slots, the slots are activated
+ in an arbitrary order when the signal is emitted.
+
+ The function returns true if it successfully connects the signal
+ to the slot. It will return false if it cannot create the
+ connection, for example, if QObject is unable to verify the
+ existence of either \a signal or \a method, or if their signatures
+ aren't compatible.
+
+ For every connection you make, a signal is emitted; two signals are emitted
+ for duplicate connections. You can break all of these connections with a
+ single disconnect() call.
+
+ The optional \a type parameter describes the type of connection
+ to establish. In particular, it determines whether a particular
+ signal is delivered to a slot immediately or queued for delivery
+ at a later time. If the signal is queued, the parameters must be
+ of types that are known to Qt's meta-object system, because Qt
+ needs to copy the arguments to store them in an event behind the

+ \class QObjectCleanupHandler
+ \brief The QObjectCleanupHandler class watches the lifetime of multiple QObjects.
+
+ \ingroup objectmodel
+
+ A QObjectCleanupHandler is useful whenever you need to know when a
+ number of \l{QObject}s that are owned by someone else have been
+ deleted. This is important, for example, when referencing memory
+ in an application that has been allocated in a shared library.
+
+ To keep track of some \l{QObject}s, create a
+ QObjectCleanupHandler, and add() the objects you are interested
+ in. If you are no longer interested in tracking a particular
+ object, use remove() to remove it from the cleanup handler. If an
+ object being tracked by the cleanup handler gets deleted by
+ someone else it will automatically be removed from the cleanup
+ handler. You can delete all the objects in the cleanup handler
+ with clear(), or by destroying the cleanup handler. isEmpty()
+ returns true if the QObjectCleanupHandler has no objects to keep
+ track of.
+
+ \sa QPointer

+ \class QPointer
+ \brief The QPointer class is a template class that provides guarded pointers to QObjects.
+
+ \ingroup objectmodel
+ \mainclass
+
+ A guarded pointer, QPointer<T>, behaves like a normal C++
+ pointer \c{T *}, except that it is automatically set to 0 when the
+ referenced object is destroyed (unlike normal C++ pointers, which
+ become "dangling pointers" in such cases). \c T must be a
+ subclass of QObject.
+
+ Guarded pointers are useful whenever you need to store a pointer
+ to a QObject that is owned by someone else, and therefore might be
+ destroyed while you still hold a reference to it. You can safely
+ test the pointer for validity.
+
+ Qt also provides QSharedPointer, an implementation of a reference-counted
+ shared pointer object, which can be used to maintain a collection of
+ references to an individual pointer.
+
+ Example:
+
+ \snippet doc/src/snippets/pointer/pointer.cpp 0
+ \dots
+ \snippet doc/src/snippets/pointer/pointer.cpp 1
+ \snippet doc/src/snippets/pointer/pointer.cpp 2
+
+ If the QLabel is deleted in the meantime, the \c label variable
+ will hold 0 instead of an invalid address, and the last line will
+ never be executed.
+
+ The functions and operators available with a QPointer are the
+ same as those available with a normal unguarded pointer, except
+ the pointer arithmetic operators (\c{+}, \c{-}, \c{++}, and
+ \c{--}), which are normally used only with arrays of objects.
+
+ Use QPointers like normal pointers and you will not need to read
+ this class documentation.
+
+ For creating guarded pointers, you can construct or assign to them
+ from a T* or from another guarded pointer of the same type. You
+ can compare them with each other using operator==() and
+ operator!=(), or test for 0 with isNull(). You can dereference
+ them using either the \c *x or the \c x->member notation.
+
+ A guarded pointer will automatically cast to a \c T *, so you can
+ freely mix guarded and unguarded pointers. This means that if you
+ have a QPointer<QWidget>, you can pass it to a function that
+ requires a QWidget *. For this reason, it is of little value to
+ declare functions to take a QPointer as a parameter; just use
+ normal pointers. Use a QPointer when you are storing a pointer
+ over time.
+
+ Note that class \c T must inherit QObject, or a compilation or
+ link error will result.

+
+ \brief The QSharedMemory class provides access to a shared memory segment.
+
+ QSharedMemory provides access to a shared memory segment by multiple
+ threads and processes. It also provides a way for a single thread or
+ process to lock the memory for exclusive access.
+
+ When using this class, be aware of the following platform
+ differences:
+
+ \list
+
+ \o Windows: QSharedMemory does not "own" the shared memory segment.
+ When all threads or processes that have an instance of QSharedMemory
+ attached to a particular shared memory segment have either destroyed
+ their instance of QSharedMemory or exited, the Windows kernel
+ releases the shared memory segment automatically.
+
+ \o Unix: QSharedMemory "owns" the shared memory segment. When the
+ last thread or process that has an instance of QSharedMemory
+ attached to a particular shared memory segment detaches from the
+ segment by destroying its instance of QSharedMemory, the Unix kernel
+ release the shared memory segment. But if that last thread or
+ process crashes without running the QSharedMemory destructor, the
+ shared memory segment survives the crash.
+
+ \o HP-UX: Only one attach to a shared memory segment is allowed per
+ process. This means that QSharedMemory should not be used across
+ multiple threads in the same process in HP-UX.
+
+ \endlist
+
+ Remember to lock the shared memory with lock() before reading from
+ or writing to the shared memory, and remember to release the lock
+ with unlock() after you are done.
+
+ Unlike QtSharedMemory, QSharedMemory automatically destroys the
+ shared memory segment when the last instance of QSharedMemory is
+ detached from the segment, and no references to the segment
+ remain. Do not mix using QtSharedMemory and QSharedMemory. Port
+ everything to QSharedMemory.

+ \class QSignalMapper
+ \brief The QSignalMapper class bundles signals from identifiable senders.
+
+ \ingroup io
+ \mainclass
+
+ This class collects a set of parameterless signals, and re-emits
+ them with integer, string or widget parameters corresponding to
+ the object that sent the signal.
+
+ The class supports the mapping of particular strings or integers
+ with particular objects using setMapping(). The objects' signals
+ can then be connected to the map() slot which will emit the
+ mapped() signal with the string or integer associated with the
+ original signalling object. Mappings can be removed later using
+ removeMappings().
+
+ Example: Suppose we want to create a custom widget that contains
+ a group of buttons (like a tool palette). One approach is to
+ connect each button's \c clicked() signal to its own custom slot;
+ but in this example we want to connect all the buttons to a
+ single slot and parameterize the slot by the button that was
+ clicked.
+
+ Here's the definition of a simple custom widget that has a single
+ signal, \c clicked(), which is emitted with the text of the button
+ that was clicked:
+
+ \snippet doc/src/snippets/qsignalmapper/buttonwidget.h 0
+ \snippet doc/src/snippets/qsignalmapper/buttonwidget.h 1
+
+ The only function that we need to implement is the constructor:
+
+ \snippet doc/src/snippets/qsignalmapper/buttonwidget.cpp 0
+ \snippet doc/src/snippets/qsignalmapper/buttonwidget.cpp 1
+ \snippet doc/src/snippets/qsignalmapper/buttonwidget.cpp 2
+
+ A list of texts is passed to the constructor. A signal mapper is
+ constructed and for each text in the list a QPushButton is
+ created. We connect each button's \c clicked() signal to the
+ signal mapper's map() slot, and create a mapping in the signal
+ mapper from each button to the button's text. Finally we connect
+ the signal mapper's mapped() signal to the custom widget's \c
+ clicked() signal. When the user clicks a button, the custom
+ widget will emit a single \c clicked() signal whose argument is
+ the text of the button the user clicked.

+ \class QSocketNotifier
+ \brief The QSocketNotifier class provides support for monitoring
+ activity on a file descriptor.
+
+ \ingroup io
+
+ The QSocketNotifier makes it possible to integrate Qt's event
+ loop with other event loops based on file descriptors. For
+ example, the \l{CORBA Framework} uses it to process CORBA
+ events. File descriptor action is detected in Qt's main event
+ loop (QCoreApplication::exec()).
+
+ \target write notifiers
+
+ Once you have opened a device using a low-level (usually
+ platform-specific) API, you can create a socket notifier to
+ monitor the file descriptor. The socket notifier is enabled by
+ default, i.e. it emits the activated() signal whenever a socket
+ event corresponding to its type occurs. Connect the activated()
+ signal to the slot you want to be called when an event
+ corresponding to your socket notifier's type occurs.
+
+ There are three types of socket notifiers: read, write, and
+ exception. The type is described by the \l Type enum, and must be
+ specified when constructing the socket notifier. After
+ construction it can be determined using the type() function. Note
+ that if you need to monitor both reads and writes for the same
+ file descriptor, you must create two socket notifiers. Note also
+ that it is not possible to install two socket notifiers of the
+ same type (\l Read, \l Write, \l Exception) on the same socket.
+
+ The setEnabled() function allows you to disable as well as enable
+ the socket notifier. It is generally advisable to explicitly
+ enable or disable the socket notifier, especially for write
+ notifiers. A disabled notifier ignores socket events (the same
+ effect as not creating the socket notifier). Use the isEnabled()
+ function to determine the notifier's current status.
+
+ Finally, you can use the socket() function to retrieve the
+ socket identifier. Although the class is called QSocketNotifier,
+ it is normally used for other types of devices than sockets.
+ QTcpSocket and QUdpSocket provide notification through signals, so
+ there is normally no need to use a QSocketNotifier on them.
+
+ \section1 Notes for Windows Users
+
+ The socket passed to QSocketNotifier will become non-blocking, even if
+ it was created as a blocking socket.
+ The activated() signal is sometimes triggered by high general activity
+ on the host, even if there is nothing to read. A subsequent read from
+ the socket can then fail, the error indicating that there is no data
+ available (e.g., \c{WSAEWOULDBLOCK}). This is an operating system
+ limitation, and not a bug in QSocketNotifier.
+
+ To ensure that the socket notifier handles read notifications correctly,
+ follow these steps when you receive a notification:
+
+ \list 1
+ \o Disable the notifier.
+ \o Read data from the socket.
+ \o Re-enable the notifier if you are interested in more data (such as after
+ having written a new command to a remote server).
+ \endlist
+
+ To ensure that the socket notifier handles write notifications correctly,
+ follow these steps when you receive a notification:
+
+ \list 1
+ \o Disable the notifier.
+ \o Write as much data as you can (before \c EWOULDBLOCK is returned).
+ \o Re-enable notifier if you have more data to write.
+ \endlist
+
+ \bold{Further information:}
+ On Windows, Qt always disables the notifier after getting a notification,
+ and only re-enables it if more data is expected. For example, if data is
+ read from the socket and it can be used to read more, or if reading or
+ writing is not possible because the socket would block, in which case
+ it is necessary to wait before attempting to read or write again.
+
+ \sa QFile, QProcess, QTcpSocket, QUdpSocket

+
+/*!
+ \enum QSocketNotifier::Type
+
+ This enum describes the various types of events that a socket
+ notifier can recognize. The type must be specified when
+ constructing the socket notifier.
+
+ Note that if you need to monitor both reads and writes for the

+ also that it is not possible to install two socket notifiers of
+ the same type (Read, Write, Exception) on the same socket.

+
+/*!
+ \class QSystemSemaphore
+ \ingroup ipc
+ \since 4.4
+
+ \brief The QSystemSemaphore class provides a general counting system semaphore.
+
+ A semaphore is a generalization of a mutex. While a mutex can be
+ locked only once, a semaphore can be acquired multiple times.
+ Typically, a semaphore is used to protect a certain number of
+ identical resources.
+
+ Like its lighter counterpart QSemaphore, a QSystemSemaphore can be
+ accessed from multiple \l {QThread} {threads}. Unlike QSemaphore, a
+ QSystemSemaphore can also be accessed from multiple \l {QProcess}
+ {processes}. This means QSystemSemaphore is a much heavier class, so
+ if your application doesn't need to access your semaphores across
+ multiple processes, you will probably want to use QSemaphore.
+
+ Semaphores support two fundamental operations, acquire() and release():
+
+ acquire() tries to acquire one resource. If there isn't a resource
+ available, the call blocks until a resource becomes available. Then
+ the resource is acquired and the call returns.
+
+ release() releases one resource so it can be acquired by another
+ process. The function can also be called with a parameter n > 1,
+ which releases n resources.
+
+ A system semaphore is created with a string key that other processes
+ can use to use the same semaphore.
+
+ Example: Create a system semaphore
+ \snippet doc/src/snippets/code/src_corelib_kernel_qsystemsemaphore.cpp 0
+
+ A typical application of system semaphores is for controlling access
+ to a circular buffer shared by a producer process and a consumer
+ processes.
+
+ \section1 Platform-Specific Behavior
+
+ When using this class, be aware of the following platform
+ differences:
+
+ \bold{Windows:} QSystemSemaphore does not own its underlying system
+ semaphore. Windows owns it. This means that when all instances of
+ QSystemSemaphore for a particular key have been destroyed, either by
+ having their destructors called, or because one or more processes
+ crash, Windows removes the underlying system semaphore.
+
+ \bold{Unix:}
+
+ \list
+ \o QSystemSemaphore owns the underlying system semaphore
+ in Unix systems. This means that the last process having an instance of
+ QSystemSemaphore for a particular key must remove the underlying
+ system semaphore in its destructor. If the last process crashes
+ without running the QSystemSemaphore destructor, Unix does not
+ automatically remove the underlying system semaphore, and the
+ semaphore survives the crash. A subsequent process that constructs a
+ QSystemSemaphore with the same key will then be given the existing
+ system semaphore. In that case, if the QSystemSemaphore constructor
+ has specified its \l {QSystemSemaphore::AccessMode} {access mode} as
+ \l {QSystemSemaphore::} {Open}, its initial resource count will not
+ be reset to the one provided but remain set to the value it received
+ in the crashed process. To protect against this, the first process
+ to create a semaphore for a particular key (usually a server), must
+ pass its \l {QSystemSemaphore::AccessMode} {access mode} as \l
+ {QSystemSemaphore::} {Create}, which will force Unix to reset the
+ resource count in the underlying system semaphore.
+
+ \o When a process using QSystemSemaphore terminates for
+ any reason, Unix automatically reverses the effect of all acquire
+ operations that were not released. Thus if the process acquires a
+ resource and then exits without releasing it, Unix will release that
+ resource.
+ \endlist
+
+ \sa QSharedMemory, QSemaphore
+ */
+
+/*!
+ Requests a system semaphore for the specified \a key. The parameters
+ \a initialValue and \a mode are used according to the following
+ rules, which are system dependent.
+
+ In Unix, if the \a mode is \l {QSystemSemaphore::} {Open} and the
+ system already has a semaphore identified by \a key, that semaphore
+ is used, and the semaphore's resource count is not changed, i.e., \a
+ initialValue is ignored. But if the system does not already have a
+ semaphore identified by \a key, it creates a new semaphore for that
+ key and sets its resource count to \a initialValue.
+
+ In Unix, if the \a mode is \l {QSystemSemaphore::} {Create} and the
+ system already has a semaphore identified by \a key, that semaphore
+ is used, and its resource count is set to \a initialValue. If the
+ system does not already have a semaphore identified by \a key, it
+ creates a new semaphore for that key and sets its resource count to
+ \a initialValue.
+
+ In Windows, \a mode is ignored, and the system always tries to
+ create a semaphore for the specified \a key. If the system does not
+ already have a semaphore identified as \a key, it creates the
+ semaphore and sets its resource count to \a initialValue. But if the
+ system already has a semaphore identified as \a key it uses that
+ semaphore and ignores \a initialValue.
+
+ The \l {QSystemSemaphore::AccessMode} {mode} parameter is only used
+ in Unix systems to handle the case where a semaphore survives a
+ process crash. In that case, the next process to allocate a
+ semaphore with the same \a key will get the semaphore that survived
+ the crash, and unless \a mode is \l {QSystemSemaphore::} {Create},
+ the resource count will not be reset to \a initialValue but will
+ retain the initial value it had been given by the crashed process.

+ underlying system semaphore is not removed from the system unless
+ this instance of QSystemSemaphore is the last one existing for that
+ system semaphore.
+
+ Two important side effects of the destructor depend on the system.
+ In Windows, if acquire() has been called for this semaphore but not
+ release(), release() will not be called by the destructor, nor will
+ the resource be released when the process exits normally. This would
+ be a program bug which could be the cause of a deadlock in another
+ process trying to acquire the same resource. In Unix, acquired
+ resources that are not released before the destructor is called are
+ automatically released when the process exits.

+ that survive a crash. In Unix, when a semaphore survives a crash, we
+ need a way to force it to reset its resource count, when the system
+ reuses the semaphore. In Windows, where semaphores can't survive a
+ crash, this enum has no effect.
+
+ \value Open If the semaphore already exists, its initial resource
+ count is not reset. If the semaphore does not already exist, it is

+ whether the semaphore already exists by having survived a crash.
+ This value should be passed to the constructor, when the first

+/*!
+ \class QTimer
+ \brief The QTimer class provides repetitive and single-shot timers.
+
+ \ingroup time
+ \ingroup events
+ \mainclass
+
+ The QTimer class provides a high-level programming interface for
+ timers. To use it, create a QTimer, connect its timeout() signal
+ to the appropriate slots, and call start(). From then on it will
+ emit the timeout() signal at constant intervals.
+
+ Example for a one second (1000 millisecond) timer (from the
+ \l{widgets/analogclock}{Analog Clock} example):
+
+ \snippet examples/widgets/analogclock/analogclock.cpp 4
+ \snippet examples/widgets/analogclock/analogclock.cpp 5
+ \snippet examples/widgets/analogclock/analogclock.cpp 6
+
+ From then on, the \c update() slot is called every second.
+
+ You can set a timer to time out only once by calling
+ setSingleShot(true). You can also use the static
+ QTimer::singleShot() function to call a slot after a specified
+ interval:
+
+ \snippet doc/src/snippets/timers/timers.cpp 3
+
+ In multithreaded applications, you can use QTimer in any thread
+ that has an event loop. To start an event loop from a non-GUI
+ thread, use QThread::exec(). Qt uses the the timer's
+ \l{QObject::thread()}{thread affinity} to determine which thread
+ will emit the \l{QTimer::}{timeout()} signal. Because of this, you
+ must start and stop the timer in its thread; it is not possible to
+ start a timer from another thread.
+
+ As a special case, a QTimer with a timeout of 0 will time out as
+ soon as all the events in the window system's event queue have
+ been processed. This can be used to do heavy work while providing
+ a snappy user interface:
+
+ \snippet doc/src/snippets/timers/timers.cpp 4
+ \snippet doc/src/snippets/timers/timers.cpp 5
+ \snippet doc/src/snippets/timers/timers.cpp 6
+
+ \c processOneThing() will from then on be called repeatedly. It
+ should be written in such a way that it always returns quickly
+ (typically after processing one data item) so that Qt can deliver
+ events to widgets and stop the timer as soon as it has done all
+ its work. This is the traditional way of implementing heavy work
+ in GUI applications; multithreading is now becoming available on
+ more and more platforms, and we expect that zero-millisecond
+ QTimers will gradually be replaced by \l{QThread}s.
+
+ Note that QTimer's accuracy depends on the underlying operating
+ system and hardware. Most platforms support an accuracy of
+ 1 millisecond, but Windows 98 supports only 55. If Qt is
+ unable to deliver the requested number of timer clicks, it will
+ silently discard some.
+
+ An alternative to using QTimer is to call QObject::startTimer()
+ for your object and reimplement the QObject::timerEvent() event
+ handler in your class (which must inherit QObject). The
+ disadvantage is that timerEvent() does not support such
+ high-level features as single-shot timers or signals.
+
+ Another alternative to using QTimer is to use QBasicTimer. It is
+ typically less cumbersome than using QObject::startTimer()
+ directly. See \l{Timers} for an overview of all three approaches.
+
+ Some operating systems limit the number of timers that may be
+ used; Qt tries to work around these limitations.

+ \class QTranslator
+
+ \brief The QTranslator class provides internationalization support for text
+ output.
+
+ \ingroup i18n
+ \ingroup environment
+ \mainclass
+
+ An object of this class contains a set of translations from a
+ source language to a target language. QTranslator provides
+ functions to look up translations in a translation file.
+ Translation files are created using \l{Qt Linguist}.
+
+ The most common use of QTranslator is to: load a translation
+ file, install it using QApplication::installTranslator(), and use
+ it via QObject::tr(). Here's the \c main() function from the
+ \l{linguist/hellotr}{Hello tr()} example:
+
+ \snippet examples/linguist/hellotr/main.cpp 2
+
+ Note that the translator must be created \e before the
+ application's widgets.
+
+ Most applications will never need to do anything else with this
+ class. The other functions provided by this class are useful for
+ applications that work on translator files.
+
+ \section1 Looking up Translations
+
+ It is possible to look up a translation using translate() (as tr()
+ and QApplication::translate() do). The translate() function takes
+ up to three parameters:
+
+ \list
+ \o The \e context - usually the class name for the tr() caller.
+ \o The \e {source text} - usually the argument to tr().
+ \o The \e disambiguation - an optional string that helps disambiguate
+ different uses of the same text in the same context.
+ \endlist
+
+ For example, the "Cancel" in a dialog might have "Anuluj" when the
+ program runs in Polish (in this case the source text would be
+ "Cancel"). The context would (normally) be the dialog's class
+ name; there would normally be no comment, and the translated text
+ would be "Anuluj".
+
+ But it's not always so simple. The Spanish version of a printer
+ dialog with settings for two-sided printing and binding would
+ probably require both "Activado" and "Activada" as translations
+ for "Enabled". In this case the source text would be "Enabled" in
+ both cases, and the context would be the dialog's class name, but
+ the two items would have disambiguations such as "two-sided printing"
+ for one and "binding" for the other. The disambiguation enables the
+ translator to choose the appropriate gender for the Spanish version,
+ and enables Qt to distinguish between translations.
+
+ \section1 Using Multiple Translations
+
+ Multiple translation files can be installed in an application.
+ Translations are searched for in the reverse order in which they were
+ installed, so the most recently installed translation file is searched
+ for translations first and the earliest translation file is searched
+ last. The search stops as soon as a translation containing a matching
+ string is found.
+
+ This mechanism makes it possible for a specific translation to be
+ "selected" or given priority over the others; simply uninstall the
+ translator from the application by passing it to the
+ QApplication::removeTranslator() function and reinstall it with
+ QApplication::installTranslator(). It will then be the first
+ translation to be searched for matching strings.
+
+ \sa QApplication::installTranslator(), QApplication::removeTranslator(),
+ QObject::tr(), QApplication::translate(), {I18N Example},
+ {Hello tr() Example}, {Arrow Pad Example}, {Troll Print Example}

+ The previous contents of this translator object are discarded.
+
+ If the file name does not exist, other file names are tried

+/*!
+ \class QVariant
+ \brief The QVariant class acts like a union for the most common Qt data types.
+
+ \ingroup objectmodel
+ \ingroup misc
+ \ingroup shared
+ \mainclass
+
+ Because C++ forbids unions from including types that have
+ non-default constructors or destructors, most interesting Qt
+ classes cannot be used in unions. Without QVariant, this would be
+ a problem for QObject::property() and for database work, etc.
+
+ A QVariant object holds a single value of a single type() at a
+ time. (Some type()s are multi-valued, for example a string list.)
+ You can find out what type, T, the variant holds, convert it to a
+ different type using convert(), get its value using one of the
+ toT() functions (e.g., toSize()) and check whether the type can
+ be converted to a particular type using canConvert().
+
+ The methods named toT() (e.g., toInt(), toString()) are const. If
+ you ask for the stored type, they return a copy of the stored
+ object. If you ask for a type that can be generated from the
+ stored type, toT() copies and converts and leaves the object
+ itself unchanged. If you ask for a type that cannot be generated
+ from the stored type, the result depends on the type; see the
+ function documentation for details.
+
+ Here is some example code to demonstrate the use of QVariant:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qvariant.cpp 0
+
+ You can even store QList<QVariant> and QMap<QString, QVariant>
+ values in a variant, so you can easily construct arbitrarily
+ complex data structures of arbitrary types. This is very powerful
+ and versatile, but may prove less memory and speed efficient than
+ storing specific types in standard data structures.
+
+ QVariant also supports the notion of null values, where you have
+ a defined type with no value set.

+ QVariant can be extended to support other types than those
+ mentioned in the \l Type enum. See the \l QMetaType documentation
+ for details.
+
+ \section1 A Note on GUI Types
+
+ Because QVariant is part of the QtCore library, it cannot provide
+ conversion functions to data types defined in QtGui, such as
+ QColor, QImage, and QPixmap. In other words, there is no \c
+ toColor() function. Instead, you can use the QVariant::value() or
+ the qVariantValue() template function. For example:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qvariant.cpp 2
+
+ The inverse conversion (e.g., from QColor to QVariant) is
+ automatic for all data types supported by QVariant, including
+ GUI-related types:
+
+ \snippet doc/src/snippets/code/src_corelib_kernel_qvariant.cpp 3
+
+ \section1 Using canConvert() and convert() Consecutively
+
+ When using canConvert() and convert() consecutively, it is possible for
+ canConvert() to return true, but convert() to return false. This
+ is typically because canConvert() only reports the general ability of
+ QVariant to convert between types given suitable data; it is still
+ possible to supply data which cannot actually be converted.
+
+ For example, canConvert() would return true when called on a variant
+ containing a string because, in principle, QVariant is able to convert
+ strings of numbers to integers.
+ However, if the string contains non-numeric characters, it cannot be
+ converted to an integer, and any attempt to convert it will fail.
+ Hence, it is important to have both functions return true for a
+ successful conversion.

+ you can register a HANDLE to an event and get notification when
+ that event becomes signalled. The state of the event is not modified
+ in the process so if it is a manual reset event you will need to
+ reset it after the notification.
