Member Function Documentation

event()

bool QThreadsEventBridge::event ( QEvent * event )

protected

receives a QEvent from QApplication and delivers the contents to a registered CuThreadsEventBridgeListener on the main thread.

Parameters

event

a QEvent that wraps a CuEventI.

If the QEvent::type is QEvent::User + 101, then QEvent is safely casted to a CuEvent_Qt object. CuEvent_Qt contains a CuEventI instance, that is delivered to a registered CuThreadsEventBridgeListener.

Returns

true if the event is a CuEvent_Qt

QObject::event(event) otherwise

CuThreadsEventBridgeListener *

l

)

set the event bridge listener on the bridge
