Intercept ShowDesktop event

[Lele]

Hi,
maybe thi is Windows specific.
Is there a way to intercept the ShowDesktop event inside a qt application.
I would like to minimize my window when that happens.
I'm using a frameless window, so I would like the same behaviour as an ordinary window.

bye

If it is sent as a Windows native event, you can reimplement QWidget::winEvent() or QCoreApplication::winEventFilter().

Yes, I tried that but I'm not sure I can intercept that particular event.
Maybe that one is more related to the QApplication rather than the widget.

thanks

It might be forwarded only to top level widgets(main windows), because it makes no sense to send such an event to a child widget.

So try catching it in the main window's winEvent.

Applying a filter on the application object should work. You should intercept all such events passing through the application this way.
