[Qt-interest] QT-X11 Display and Window handle

[Anil H]

Hi,

I am trying out an X11 based QT4.5.2 application on Red Hat EL5.
The application requires X11 window to be embedded in the QT-GUI
and the embedded window displays images/video.
So I require an X11 display and window handle which has been already opened
by QT.

QT documentation recommends *not* to use *
QPaintDevice::x11AppDisplay ()
QPaintDevice::x11AppRootWindow() API's* * *since it is provided only for QT3
compatibility.
I tried out X11 C API's  *XOpenDisplay() *  & *RootWindow*() .
But this opens up another window which can't be embedded in the QT GUI.

How to get X11Display and window handle which has already been opened by QT
?

Thanks and regards
Anil H
