Description
QMainWindow (A) has a sub QMainWindow(B) with its parent as (A). The window (B) has a QGLWidget.
When the subwindow (B) is minimized, it still shows the glwidget.
Please find the test app attached.
Note that, if the subwindow (B) doesnt have a parent, all works good.
Using qtbug28367.tar:
- Launch app, minimize subwindow: SubWindow shrinks to
size 0,0 (showing only title bar) and moves above top-left corner of task bar. On Windows 7, an additional red bar can be observed over the minimized sub window.
That is, the iconified sub window does not hide behind the task bar as do the others. Identical behaviour in Qt 4.8, 5.
Option -n turns off parenting, restoring normal behaviour. Option -l creates a label instead of a GL widget (same bug).
