Mouse events occur when a mouse button is pressed or released inside a widget, or when the mouse cursor is moved. Mouse move events will occur only when a mouse button is pressed down, unless mouse tracking has been enabled with QWidget::setMouseTracking(). Qt automatically grabs the mouse when a mouse button is pressed inside a widget; the widget will continue to receive mouse events until the last mouse button is released. A mouse event contains a special accept flag that indicates whether the receiver wants the event. You should call ignore() if the mouse event is not handled by your widget. A mouse event is propagated up the parent widget chain until a widget accepts it with accept(), or an event filter consumes it. \note If a mouse event is propagated to a \l{QWidget}{widget} for which Qt::WA_NoMousePropagation has been set, that mouse event will not be propagated further up the parent widget chain. The state of the keyboard modifier keys can be found by calling the \l{QInputEvent::modifiers()}{modifiers()} function, inherited from QInputEvent. The functions pos(), x(), and y() give the cursor position relative to the widget that receives the mouse event. If you move the widget as a result of the mouse event, use the global position returned by globalPos() to avoid a shaking motion. The QWidget::setEnabled() function can be used to enable or disable mouse and keyboard events for a widget. Reimplement the QWidget event handlers, QWidget::mousePressEvent(), QWidget::mouseReleaseEvent(), QWidget::mouseDoubleClickEvent(), and QWidget::mouseMoveEvent() to receive mouse events in your own widgets. \sa QWidget::setMouseTracking() QWidget::grabMouse() QCursor::pos() */ /*!

They are also sent when you call QWidget::close() to close a widget programmatically. Close events contain a flag that indicates whether the receiver wants the widget to be closed or not. When a widget accepts the close event, it is hidden (and destroyed if it was created with the Qt::WA_DeleteOnClose flag). If it refuses to accept the close event nothing happens. (Under X11 it is possible that the window manager will forcibly close the window; but at the time of writing we are not aware of any window manager that does this.) The event handler QWidget::closeEvent() receives close events. The default implementation of this event handler accepts the close event. If you do not want your widget to be hidden, or want some special handing, you should reimplement the event handler and ignore() the event. The \l{mainwindows/application#close event handler}{closeEvent() in the Application example} shows a close event handler that asks whether to save a document before closing. If you want the widget to be deleted when it is closed, create it with the Qt::WA_DeleteOnClose flag. This is very useful for independent top-level windows in a multi-window application. \l{QObject}s emits the \l{QObject::destroyed()}{destroyed()} signal when they are deleted. If the last top-level window is closed, the QApplication::lastWindowClosed() signal is emitted.

Input methods are widely used to enter text for languages with non-Latin alphabets. Note that when creating custom text editing widgets, the Qt::WA_InputMethodEnabled window attribute must be set explicitly (using the QWidget::setAttribute() function) in order to receive input method events. The events are of interest to authors of keyboard entry widgets who want to be able to correctly handle languages with complex character input. Text input in such languages is usually a three step process: \list 1 \o \bold{Starting to Compose} When the user presses the first key on a keyboard, an input context is created. This input context will contain a string of the typed characters. \o \bold{Composing} With every new key pressed, the input method will try to create a matching string for the text typed so far called preedit string. While the input context is active, the user can only move the cursor inside the string belonging to this input context. \o \bold{Completing} At some point, the user will activate a user interface component (perhaps using a particular key) where they can choose from a number of strings matching the text they have typed so far. The user can either confirm their choice cancel the input; in either case the input context will be closed. \endlist QInputMethodEvent models these three stages, and transfers the information needed to correctly render the intermediate result. A QInputMethodEvent has two main parameters: preeditString() and commitString(). The preeditString() parameter gives the currently active preedit string. The commitString() parameter gives a text that should get added to (or replace parts of) the text of the editor widget. It usually is a result of the input operations and has to be inserted to the widgets text directly before the preedit string. If the commitString() should replace parts of the of the text in the editor, replacementLength() will contain the number of characters to be replaced. replacementStart() contains the position at which characters are to be replaced relative from the start of the preedit string. A number of attributes control the visual appearance of the preedit string (the visual appearance of text outside the preedit string is controlled by the widget only). The AttributeType enum describes the different attributes that can be set. A class implementing QWidget::inputMethodEvent() or QGraphicsItem::inputMethodEvent() should at least understand and honor the \l TextFormat and \l Cursor attributes. Since input methods need to be able to query certain properties from the widget or graphics item, subclasses must also implement QWidget::inputMethodQuery() and QGraphicsItem::inputMethodQuery(), respectively. When receiving an input method event, the text widget has to performs the following steps: \list 1 \o If the widget has selected text, the selected text should get removed. \o Remove the text starting at replacementStart() with length replacementLength() and replace it by the commitString(). If replacementLength() is 0, replacementStart() gives the insertion position for the commitString(). When doing replacement the area of the preedit string is ignored, thus a replacement starting at -1 with a length of 2 will remove the last character before the preedit string and the first character afterwards, and insert the commit string directly before the preedit string. If the widget implements undo/redo, this operation gets added to the undo stack. \o If there is no current preedit string, insert the preeditString() at the current cursor position; otherwise replace the previous preeditString with the one received from this event. If the widget implements undo/redo, the preeditString() should not influence the undo/redo stack in any way. The widget should examine the list of attributes to apply to the preedit string. It has to understand at least the TextFormat and Cursor attributes and render them as specified. \endlist \sa QInputContext */ /*! \enum QInputMethodEvent::AttributeType \value TextFormat A QTextCharFormat for the part of the preedit string specified by start and length. value contains a QVariant of type QTextFormat specifying rendering of this part of the preedit string.

Most of the time you will want to deal with events from the tablet as if they were events from a mouse; for example, you would retrieve the cursor position with x(), y(), pos(), globalX(), globalY(), and globalPos(). In some situations you may wish to retrieve the extra information provided by the tablet device driver; for example, you might want to do subpixeling with higher resolution coordinates or you may want to adjust color brightness based on pressure. QTabletEvent allows you to read the pressure(), the xTilt(), and yTilt(), as well as the type of device being used with device() (see \l{TabletDevice}). It can also give you the minimum and maximum values for each device's pressure and high resolution coordinates. A tablet event contains a special accept flag that indicates whether the receiver wants the event. You should call QTabletEvent::accept() if you handle the tablet event; otherwise it will be sent to the parent widget. The exception are TabletEnterProximity and TabletLeaveProximity events, these are only sent to QApplication and don't check whether or not they are accepted. The QWidget::setEnabled() function can be used to enable or disable mouse and keyboard events for a widget. The event handler QWidget::tabletEvent() receives all three types of tablet events. Qt will first send a tabletEvent then, if it is not accepted, it will send a mouse event. This allows applications that don't utilize tablets to use a tablet like a mouse, while also enabling those who want to use both tablets and mouses differently. \section1 Notes for X11 Users Qt uses the following hard-coded names to identify tablet devices from the xorg.conf file on X11 (apart from IRIX): 'stylus', 'pen', and 'eraser'.

To receive touch events, widgets have to have the Qt::WA_AcceptTouchEvents attribute set and graphics items need to have the \l{QGraphicsItem::setAcceptTouchEvents()}{acceptTouchEvents} attribute set to true. All touch events are of type QEvent::TouchBegin, QEvent::TouchUpdate, or QEvent::TouchEnd. The touchPoints() function returns a list of all touch points contained in the event. Information about each touch point can be retrieved using the QTouchEvent::TouchPoint class. The Qt::TouchPointState enum describes the different states that a touch point may have. Similar to QMouseEvent, Qt automatically grabs each touch point on the first press inside a widget; the widget will receive all updates for the touch point until it is released. Note that it is possible for a widget to receive events for multiple touch points, and that multiple widgets may be receiving touch events at the same time. A touch event contains a special accept flag that indicates whether the receiver wants the event. By default, the event is accepted. You should call ignore() if the touch event is not handled by your widget. A QEvent::TouchBegin event is propagated up the parent widget chain until a widget accepts it with accept(), or an event filter consumes it. If the QEvent::TouchBegin event is neither accepted nor consumed, then mouse events are simulated from the state of the first touch point. Reimplement QWidget::event() for widgets and QGraphicsItem::sceneEvent() for items in a graphics view to receive touch events. \sa QTouchEvent::TouchPoint, Qt::TouchPointState, Qt::WA_AcceptTouchEvents, QGraphicsItem::acceptTouchEvents() */ /*! \enum Qt::TouchPointState \since 4.6 This enum represents the state of a touch point at the time the QTouchEvent occurred. \value TouchPointPressed The touch point is now pressed. \value TouchPointMoved The touch point moved. \value TouchPointStationary The touch point did not move. \value TouchPointReleased The touch point was released. \omitvalue TouchPointStateMask \omitvalue TouchPointPrimary */ /*! \enum QTouchEvent::DeviceType This enum represents the type of device that generated a QTouchEvent. \value TouchScreen In this type of device, the touch surface and display are integrated. This means the surface and display typically have the same size, such that there is a direct relationship between the touch points' physical positions and the coordinate reported by QTouchEvent::TouchPoint. As a result, Qt allows the user to interact directly with multiple QWidgets and QGraphicsItems at the same time. \value TouchPad In this type of device, the touch surface is separate from the display. There is not a direct relationship between the physical touch location and the on-screen coordinates. Instead, they are calculated relative to the current mouse position, and the user must use the touch-pad to move this reference point. Unlike touch-screens, Qt allows users to only interact with a single QWidget or QGraphicsItem at a time. */ /*!
