Detailed Description

QPushButton which can display another widget or a text/icon alternatively. The widget can be showable and if not shown an icon or text will be displayed. when configured without widget display, only the icon or text will be shown.

All widgets which have a notifyUpdate(int) method will blink in red if the method is called and the widget is currently shown. When clicked the widget will stop blinking. This can be used to indicate that something has changed on the widget.
