This virtual function receives events to an object and should return true if the event e was recognized and processed.
The event() function can be reimplemented to customize the behavior of an object.
Make sure you call the parent event class implementation for all the events you did not handle.
Example:
Reimplemented from QObject.
Definition at line 1704 of file qsgthreadedrenderloop.cpp.
References QAnimationDriver::advance(), emit, QObject::event(), QSGContext::isVSyncDependent(), Q_ASSERT, qCDebug, QEvent::Timer, QSGRenderLoop::timeToIncubate(), and QEvent::type().
|
overrideprivatevirtual |
Filters events if this object has been installed as an event filter for the watched object.
In your reimplementation of this function, if you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.
Example:
Notice in the example above that unhandled events are passed to the base class's eventFilter() function, since the base class might have reimplemented eventFilter() for its own internal purposes.
Some events, such as \l QEvent::ShortcutOverride must be explicitly accepted (by calling \l {QEvent::}{accept()} on them) in order to prevent propagation.
