[Qt-interest] hi native window

[Justin Seeley]

hi, all
I need to use a native window in my widget because of a third-party
library,I got the handle by windId(), and reimplemented winEvent(),
and it works though not good , but that is the case when the widget is
the top widget.
But when I put the widget in a layout and then in another widget, the
window  doesn't work anymore.

I'm not sure how Qt generates a window in the low layer and if the
Windows(ps, I'm using XP) Message Loop is still the backbone of Qt, so
I'm  hoping to get some clue from you.

Thanks.
