Hi guys:
I'm doing with a customlize title bar combined with a QGLWidget.
My trouble is that when i drag the title bar, it should behave like
a native title bar(move its content, i.e. the GLWidget, along with
itself), BUT in fact, the GLWidget keep blinking and sometimes the
widget woule *disappear*(move to some area that cannot be seen, out
of the screen rect), it's weird.
Here's some basic information:
* QGLWidget has been wrapped in a dummy widget as th QtDoc says;
* Both widget has the flags: Frameless & Window;
* Title bar widget use the geometry of the GLWidget to locate
itself(in its own paintEvent()), and use GLWidget.move() to change
the pos of GLWidget in the mouseMoveEvent();
* widget.update() method is called at every possible place;
* I tried the customlize title in a common non-openGL widget, the
widget blinking issue not came to me.
I know not much about openGL, but it seems to be the problem of
QGLWidget.
Any advise would be appreciated.
Thx.
