QGLWidget Resize Problem

The minimum width of a top level window is controlled by the window manager. There is not much you can do about it, you can only ask the window manager not to manage your window by passing proper hints in the widget constructor.

Thanks once again.

You are right. I made my widget subwindow.
Qt::SubWindow parameter worked for me.
