When a TAction event fires, the \"Sender\" is always the action itself. Usually that\'s the most useful, but is it somehow possible to find out who triggered the action\'s OnExe

    Knowing what button triggered the action sort of goes against the point of using actions - an action may be triggered by a button click, or a menu click, or any number of other user activities. Actions exist to unify the state management of enable/disabled and click handling between buttons and menus.

    If you want to know which button fired the action because you want to perform a slightly different operation, or "flavor" the operation differently, then perhaps TAction isn't the right solution for what you want to do.
