Hello all,
I'm trying to write a global proceedure to convert all QTapAndHoldGesture
events to mouse double click events. I thought this should be trivial, but
it's really stumping me.
I setup an event filter globally for my QApplication and grab the gesture
as follow:
app.installEventFilter(&myobj);
mainWin->grabGesture(Qt::TapAndHoldGesture);
And then I have an event filter as follows:
bool myObject::eventFilter(QObject *obj, QEvent *e)
{
if(e->type() == QEvent::Gesture)
{
QGestureEvent *event = static_cast<QGestureEvent*>(e);
if(QGesture *gest = event->gesture(Qt::TapAndHoldGesture))
{
QTapAndHoldGesture *tah = static_cast<QTapAndHoldGesture *>(gest);
QMouseEvent dblClk(QEvent::MouseButtonDblClick,
tah->position().toPoint(), Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);
QApplication::sendEvent(obj, &dblClk);
return true;
}
}
}
I receive the gesture events fine, but for some reason when none of my
widgets receive the double click events. I've tried lots of different
options for instantiating my QMouseEvent. I've tried calling grabMouse on
the widget before sending the event, but still nothing receives double
click events. Does anyone have an idea of why none of my widgets receive
the double click events?
Thanks!
Josh
