Description
Indicates whether the action can execute its function.
Do not call the HandlesTarget method. This method is called automatically when the user invokes an object (such as a tool button or menu item) that is linked to this action. The HandlesTarget method provides the action object with an opportunity to indicate whether it is appropriate to execute at this time with the object specified by the Target parameter as a "target".
Target is the currently active object.
HandlesTarget checks that the target is a TCustomListControl descendant (or that the ListControl property is set if Target is nil (Delphi) or NULL (C++)). HandlesTarget returns true if there is a list control to act as target, false otherwise.
