QDockWidget::setTitleBarWidget can prevent shortcuts from working. It happens if a dock widget has a QGraphicsView, for instance.
An example has been attached where shortcut Qt::Key_1 will trigger message dialog. However, if one clicks on the red item in the graphics view (inside a dock widget), the shortcut cannot be activated afterwards.
