TWindowClose.UpdateTarget Method
|
RAD Studio VCL Reference
|
|
|
Enables or disables the action, depending on whether the target form an active child.
procedure UpdateTarget(Target: TObject); override;
virtual __fastcall UpdateTarget(TObject * Target);
Do not call the UpdateTarget method. This method is called automatically so that actions can update themselves according to current conditions.
In TWindowClose, UpdateTarget checks that the target object is an MDI parent form with a non-nil (Delphi) or NULL (C++) ActiveMDIChild property. If so, UpdateTarget sets the Enabled property to true. Otherwise, it sets Enabled to false.
