Why are actions limited to menus and toolbars?

Hmm... when I think of "action" I belive this is something that I can trigger. With checkboxes I don't see how marking it as checked or not triggeres some action. Of course, an action can be checkable, but it still is (logically) associated with some action being taken. For me it would make more sense to associate an action with a QPushButton more than with QCheckBox. But we have QToolButton for that An action associates things like text, icon, tool tip, etc. not only a slot which will get run after activating the widget. Both QPushButton and QCheckBox (and QRadioButton too) are just not meant for actions. If you want, you can always subclass them and add a feature of associating an action with each of them. There is a changed() signal in QAction. I belive you can use it for that.
