Member Function Documentation

◆ eventFilter()

bool ProximityEventFilter::eventFilter ( QObject watched,
QEvent event 
)
overridevirtual

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.

Warning
If you delete the receiver object in this function, be sure to return true. Otherwise, Qt will forward the event to the deleted object and the program might crash.
