This is the main event handler; it handles event event. You can reimplement this function in a subclass, but we recommend using one of the specialized event handlers instead.
Key press and release events are treated differently from other events. event() checks for Tab and Shift+Tab and tries to move the focus appropriately. If there is no widget to move the focus to (or the key press is not Tab or Shift+Tab), event() calls keyPressEvent().
Mouse and tablet event handling is also slightly special: only when the widget is \l enabled, event() will call the specialized handlers such as mousePressEvent(); otherwise it will discard the event.
This function returns true
if the event was recognized, otherwise it returns false
. If the recognized event was accepted (see \l QEvent::accepted), any further processing such as event propagation to the parent widget stops.

This event handler, for event event, can be reimplemented in a subclass to receive mouse double click events for the widget.
The default implementation calls mousePressEvent().

This event handler, for event event, can be reimplemented in a subclass to receive mouse press events for the widget.
If you create new widgets in the mousePressEvent() the mouseReleaseEvent() may not end up where you expect, depending on the underlying window system (or X11 window manager), the widgets' location and maybe more.
The default implementation implements the closing of popup widgets when you click outside the window. For other widget types it does nothing.

This event handler can be reimplemented in a subclass to receive widget move events which are passed in the event parameter. When the widget receives this event, it is already at the new position.
The old position is accessible through QMoveEvent::oldPos().

This event handler can be reimplemented in a subclass to receive paint events passed in event.
A paint event is a request to repaint all or part of a widget. It can happen for one of the following reasons:
\list
Many widgets can simply repaint their entire surface when asked to, but some slow widgets need to optimize by painting only the requested region: QPaintEvent::region(). This speed optimization does not change the result, as painting is clipped to that region during event processing. QListView and QTableView do this, for example.
Qt also tries to speed up painting by merging multiple paint events into one. When update() is called several times or the window system sends several paint events, Qt merges these events into one event with a larger region (see QRegion::united()). The repaint() function does not permit this optimization, so we suggest using update() whenever possible.
When the paint event occurs, the update region has normally been erased, so you are painting on the widget's background.
The background can be set using setBackgroundRole() and setPalette().
Since Qt 4.0, QWidget automatically double-buffers its painting, so there is no need to write double-buffering code in paintEvent() to avoid flicker.

This event handler can be reimplemented in a subclass to receive widget resize events which are passed in the event parameter. When resizeEvent() is called, the widget already has its new geometry. The old size is accessible through QResizeEvent::oldSize().
The widget will be erased and receive a paint event immediately after processing the resize event. No drawing need be (or should be) done inside this handler.
