Qt and the Win32 API.

[Coises]

This is similar to (though more complex than) a problem on which I’m working. The HWND part is pretty simple.

If you create and instantiate a class derived from QWidget, you can use QWidget::winId to get an HWND (assuming you’re sure you’re running under Windows, of course). It doesn’t matter that you don’t want to see the window... you just never show it. Use QWidget::winEvent to capture the messages.
