I succeeded reparenting the system window that we get from the host as a
QWidget. It just worked the straight-forward way by just compiling with
static runtime (/MT).
When I tested reparenting the system window with dynamic runtime (/MD)
There are still some open issues tho. I.e. the test if qApp exists is
not really working for a DLL. It basically creates a new QApplication
every time you instantiate a plugin.
The good thing is: I got someone from trolltech who will spend his next
'creative friday' on the open issues to open up qt to the vst world.
I'll keep you updated.
