getWidgetAt/getChildAt(global position) for elements under QGraphicsProxyWidget

[lgvier]

Hello folks,

I'm looking for a way to retrieve what widget is under position x,y including the ones inside QGraphicsProxyWidgets.
QApplication and QWidget's methods return the scene widget instead of the widget inside it.

If that's not possible.. if there's a way to post a mouse event "globally" that will reach the children widget at certain position, that would do the trick. I'm using postEvent, but I have to pass the target widget, so I have to find that widget first.

Thanks a lot for any help

Hello,

I'll answer myself in case somebody needs the same thing in the future..

You map the global coordinates to the view:

QPoint relativePos = view->mapFromGlobal(pos);

QPoint relativePos = view->mapFromGlobal(pos);

To copy to clipboard, switch view to plain text mode 

Then the view local coordinates to the scene:

QPointF scenePos = graphicsView->mapToScene(relativePos);

QPointF scenePos = graphicsView->mapToScene(relativePos);

To copy to clipboard, switch view to plain text mode 

And finally the scene pos to the GraphicsItem pos

QPointF sceneRelPos = item->mapFromScene(scenePos);

QPointF sceneRelPos = item->mapFromScene(scenePos);

To copy to clipboard, switch view to plain text mode 

Now proxy->widget()->childAt(sceneRelPos.toPoint) will return the widget that was hit inside the proxy.

Cheers

Excuse me, what can we use these things to do??
Can we retrieve the position of the mouse out of the application interface??
Thanks
