hi, I was wondering if integrating DirectX with Qt is possible. It seems to be as I found some mailing lists with references to that. But I can't find HOW to do it. So if anybody here can help me (links, explanations, whatever can help me ^^)

I have read an idea on a mail list that used something like that:

1. Derive an object from QWidget and define a IDirect3DDevice9* as a member.

2. In the constructor do the common dirext3d device initialization preparations and when creating the device use

this->topLevelWidget()->winId()

as the wHND argument of the CreateDevice method.

Also may be handle the resize situations (like retransforming the projection matrix etc.) overwriting the paintEvent of the widget.

I didnt have the chance to give it a try but will in a close future.

May be give some more ideas after that trial.
