Reg. QTBUG-34592

Is QTBUG-34592 resolved in Qt Creator 4.9.0? UI crashes while loading ActiveX control.

@ketan According to https://bugreports.qt.io/browse/QTBUG-34592 it was fixed in Qt, so seems to be a bug in Qt not QtCreator.

I'm using 5.12. So, the bug is in Qt 5.12? Also, I'm using qt source files for my development. There they have mentioned and I quote " // QTBUG-34592, accessing the 'control' property via meta object system
// may cause crashes during loading for some controls."

The discussion is from 2013 almost 6 years ago. Therefore it shall be fixed in newer releases even before Qt 5.12.
However, it may reappeared for some reason at least with a minimum likelihood.

@ketan are you sure your graphic drivers are up to date ?

Some Intel ones are known to cause trouble

@koahnig You're right. I've just migrated to Qt 5.12, before that I was using Qt Creator 3.0.0
Based on Qt 5.2.0 (MSVC 2013, 64 bit) and the ActiveX widget was working properly.

@ketan You're mixing QtCreator and Qt which are not the same.
"Based on Qt 5.2.0 (MSVC 2013, 64 bit)" - this is the Qt version which was used to build QtCreator - it is not necessarily the one you're using for your apps.
