TCustomIcon.HandleNeeded procedure
Ensures that a handle for the image has been allocated.
Declaration
procedure HandleNeeded; overrideDescription
HandleNeeded is an overridden procedure used to ensure that a
handle for the image has been allocated. HandleNeeded re-implements the
method defined in the ancestor class.
No actions are performed in the method when a valid valid has already been assigned to the shared image in the class instance.
HandleNeeded calls the CreateIconIndirect routine for the
widgetset to get the value used as the Handle for the shared image.
