Hi Roland,
On Linux (ubuntu with gnome shell) it worked without problems.
Good to know. It seems I have to move to Linux as soon as possible. Anyway
the final target of my app is Linux platform.
I will take a look at it in the next days and maybe post a patch if

Thank you! It would be great to have qmlglsrc working on Windows too.
