Detailed Description

This class exists to work around a bug in QToolButton when in MenuPopupButton mode. The correct (mouse) behavior is to display the menu with the first click, and let the user choose an item with the next click. The buggy behavior presented by the tablet is to present the menu and immediately select an item when the user performs a stylus tip click. This workaround solves this.
