[Development] QtQuick not usable on Windows tablet computers? (Was: Virtual keyboard)

[Helmut Mülner]

It looks like QtQuick on Windows table computers is severly broken:
Automatic popup of the virtual keyboard does not work. But it works with
QWidgets and QML System Dialogs.

I tried to hack around the issue by calling C++-Code to show/hide the
keyboard (using FindWindow and PostMessage) in onActiveFocusChanged. When
calling the "show" code, the keyboard pops up and disappears immediately
(This may be a problem with the virtual keyboard code).

Can anybody confirm this or prove otherwise?
