RibbonToolBarActionGroupItem should store QPointers rather than direct pointers

3 months 3 weeks ago #1 by Andres Kruse
The problem is that if you use the same QAction on multiple pages (or RibbonToolBarActionGroups), upon closing of the application, there is a dangling pointer to QAction and QWidget in RibbonToolBarControlPrivate::calculateSizeHint because the actions/widgets might already have been deleted. Replacing QAction * and QWidget with QPointer<QAction> and QPointer<QWidget> solves the problem.

actually you will also have to check if the action is non-zero..
