It would be nice to be able to globally enable/disable the icon in all QWidgets in an application aside from the QApplication::setWindowIcon() call.
Something like this:-
setApplicationIcon("my_icon.ico") 
setWidgetIcon ("my_icon.ico") << to use same icon for all widgets 
or 
setWidgetIcon ("") << to use no icon for all widgets.
