For example: + + \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 2 + + When implementing a custom widget plugin, a pointer to \QD's + current QDesignerFormEditorInterface object (\c formEditor in the + example above) is provided by the + QDesignerCustomWidgetInterface::initialize() function's parameter. + + The member sheet (and any other extension), can be retrieved by + querying \QD's extension manager using the qt_extension() + function. When you want to release the extension, you only need to + delete the pointer. + + All widgets have a default member sheet used in \QD's signals and + slots editing mode with the widget's member functions. But + QDesignerMemberSheetExtension also provides an interface for + creating custom member sheet extensions. + + \warning \QD uses the QDesignerMemberSheetExtension to facilitate + the signal and slot editing mode. Whenever a connection between + two widgets is requested, \QD will query for the widgets' member + sheet extensions. If a widget has an implemented member sheet + extension, this extension will override the default member sheet. + + To create a member sheet extension, your extension class must + inherit from both QObject and QDesignerMemberSheetExtension. Then, + since we are implementing an interface, we must ensure that it's + made known to the meta object system using the Q_INTERFACES() + macro: + + \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 3 + + This enables \QD to use qobject_cast() to query for + supported interfaces using nothing but a QObject pointer. + + In \QD the extensions are not created until they are + required. For that reason, when implementing a member sheet + extension, you must also create a QExtensionFactory, i.e a class + that is able to make an instance of your extension, and register + it using \QD's \l {QExtensionManager}{extension manager}. + + When a widget's member sheet extension is required, \QD's \l + {QExtensionManager}{extension manager} will run through all its + registered factories calling QExtensionFactory::createExtension() + for each until the first one that is able to create a member sheet + extension for that widget, is found. This factory will then make + an instance of the extension. If no such factory is found, \QD + will use the default member sheet. + + There are four available types of extensions in \QD: + QDesignerContainerExtension, QDesignerMemberSheetExtension, + QDesignerPropertySheetExtension and + QDesignerTaskMenuExtension. \QD's behavior is the same whether the + requested extension is associated with a multi page container, a + member sheet, a property sheet or a task menu. + + The QExtensionFactory class provides a standard extension + factory, and can also be used as an interface for custom + extension factories. You can either create a new + QExtensionFactory and reimplement the + QExtensionFactory::createExtension() function. For example: + + \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 4 + + Or you can use an existing factory, expanding the + QExtensionFactory::createExtension() function to make the factory + able to create a member sheet extension as well. For example: + + \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 5 + + For a complete example using an extension class, see \l + {designer/taskmenuextension}{Task Menu Extension example}. The + example shows how to create a custom widget plugin for Qt + Designer, and how to to use the QDesignerTaskMenuExtension class + to add custom items to \QD's task menu. + + \sa QExtensionFactory, QExtensionManager, {Creating Custom Widget + Extensions} +*/ + +/*! + \fn QDesignerMemberSheetExtension::~QDesignerMemberSheetExtension() + + Destroys the member sheet extension. +*/ + +/*! + \fn int QDesignerMemberSheetExtension::count() const + + Returns the extension's number of member functions. +*/ + +/*! + \fn int QDesignerMemberSheetExtension::indexOf(const QString &name) const + + Returns the index of the member function specified by the given \a + name. + + \sa memberName() +*/ + +/*! + \fn QString QDesignerMemberSheetExtension::memberName(int index) const + + Returns the name of the member function with the given \a index. + + \sa indexOf() +*/ + +/*! + \fn QString QDesignerMemberSheetExtension::memberGroup(int index) const + + Returns the name of the member group specified for the function + with the given \a index. + + \sa indexOf(), setMemberGroup() +*/ + +/*! + \fn void QDesignerMemberSheetExtension::setMemberGroup(int index, const QString &group) + + Sets the member group of the member function with the given \a + index, to \a group. + + \sa indexOf(), memberGroup() +*/ + +/*! + \fn bool QDesignerMemberSheetExtension::isVisible(int index) const + + Returns true if the member function with the given \a index is + visible in \QD's signal and slot editor, otherwise false. + + \sa indexOf(), setVisible() +*/ + +/*! + \fn void QDesignerMemberSheetExtension::setVisible(int index, bool visible) + + If \a visible is true, the member function with the given \a index + is visible in \QD's signals and slots editing mode; otherwise the + member function is hidden. + + \sa indexOf(), isVisible() +*/ + +/*! + \fn virtual bool QDesignerMemberSheetExtension::isSignal(int index) const + + Returns true if the member function with the given \a index is a + signal, otherwise false. + + \sa indexOf() +*/ + +/*! + \fn bool QDesignerMemberSheetExtension::isSlot(int index) const + + Returns true if the member function with the given \a index is a + slot, otherwise false. + + \sa indexOf() +*/ + +/*! + \fn bool QDesignerMemberSheetExtension::inheritedFromWidget(int index) const + + Returns true if the member function with the given \a index is + inherited from QWidget, otherwise false. + + \sa indexOf() +*/ + +/*! + \fn QString QDesignerMemberSheetExtension::declaredInClass(int index) const + + Returns the name of the class in which the member function with + the given \a index is declared. + + \sa indexOf() +*/ + +/*! + \fn QString QDesignerMemberSheetExtension::signature(int index) const + + Returns the signature of the member function with the given \a + index. + + \sa indexOf() +*/ + +/*! + \fn QList<QByteArray> QDesignerMemberSheetExtension::parameterTypes(int index) const + + Returns the parameter types of the member function with the given + \a index, as a QByteArray list. + + \sa indexOf(), parameterNames() +*/ + +/*! + \fn QList<QByteArray> QDesignerMemberSheetExtension::parameterNames(int index) const + + Returns the parameter names of the member function with the given + \a index, as a QByteArray list. + + \sa indexOf(), parameterTypes() +*/ |
