A question with QAction?



  • Does QAction has something like ON_UPDATE_COMMAND_UI which in MFC handle a user-interface update command message?



  • No. QAction is not a GUI element. QAction is used to describe an action for which a representation can be rendered on screen by different widgets: a menu or a toolbar or something like that. It is those that receive events that trigger a redraw.
