TBasicAction.UpdateTarget

Notify client controls when the action updates itself.

Declaration

Source position: classesh.inc line 1916

public procedure TBasicAction.UpdateTarget(

  Target: TObject

); virtual;

Description

UpdateTarget should update the client control specified by Target when the action updates itself. In TBasicAction, the implementation of UpdateTarget is empty. Descendant classes should override and implement UpdateTarget to actually update the Target object.

An application programmer should never need to call HandlesTarget directly, it will be called by the action itself when needed.
