(clug-talk) XReparentWindow??

[Jane Young]

Dear all,

I'd like to include a x11 window  from another application into qt
application window on linux. Now I can get the winIds of the X11 window and
new created qt main window.

How  can I do that? I tried XReparentWindow, but I can't see the widget, did
I do something wrong?

int main(int argc, char **argv)
{
  QApplication a(argc, argv);
     Board b; //Board is QMainWindow, coz I want menu bar in the image
     Window winId;
     b.setGeometry(0, 0, 300, 300);
      Display *displayX11;
      displayX11 = XOpenDisplay(NULL);
        a.setMainWidget(&b);
       //  b.show();
        winId = b.getWinId(); //get the winId of the X11 window

   XReparentWindow(displayX11, winId, b.winId(), 0, 0);

   XMoveResizeWindow(displayX11, winId, 0,0,300, 300);

    XMapWindow(displayX11,b.winId());

   //XCloseDisplay(displayX11);  //When I uncomment this, I will get errors
like
                                                    // X Error: BadWindow
(invalid Window parameter) 3
                                                      //Major opcode:  7
                                                      //Minor opcode:  0
                                                     // Resource id:
0xbffff978

  return a.exec();
}

Thank you for your help.
