- Description
- This function is called by the broadcaster, an XExtendedToolkit for
instance, after a key has been pressed but before it is released.
The return value decides about whether other handlers will be
called and a handling by the broadcaster will take place.
Consume the event if the action performed by the implementation
is mutualy exclusive with the default action of the broadcaster or,
when known, with that of other handlers.
Consuming this event does not prevent the pending key-release
event of beeing broadcasted.
- Parameter aEvent
-
The key event informs about the pressed key.
- Returns
-
When false is returned the other handlers are called and a
following handling of the event by the broadcaster takes place.

called and the broadcaster will take no further actions
regarding the event.
