From e05dc08ba02b4a9d893190230c8dfd2554ec4413 Mon Sep 17 00:00:00 2001 From: Oliver Wolff Date: Thu, 12 Jul 2018 13:01:14 +0200 Subject: winrt: Implement QPlatformCursor::setPos Additionally to setting the cursor position we have to make sure that enter and leave events are triggered. As WinRT at the moment only supports maximized/fullscreen native top level widgets, an enter or leave event has to be triggered, every time the cursor enters or leaves the core window. Same as is done on Windows desktop an enter event is immediately followed by a move event even for emulated mouse events.
