Description
The event handler of this event can be used for confirmation that the user really wants to accomplish an action.
In descendant classes, the OnCanActionExec event handler can be used to get the user confirmation about executing the corresponding action. For example, in TFileExit, the event handler of this event can be used for confirmation that the user really wants to close an application. You can analyze the value of the ShortCutPressed property to define whether the event is activated by pressing a keyboard key or by mouse clicking.
