public function TBasicAction.HandlesTarget( |
Target: TObject |
):Boolean; virtual; |
HandlesTarget returns True if Target is a valid client for this action and if so, if it is in a suitable state to execute the action. An application programmer should never need to call HandlesTarget directly, it will be called by the action itself when needed.
In TBasicAction this method is empty; descendant classes should override this method to implement appropriate checks.
