TMenuItem.SetAction procedure

Declaration

procedure SetAction(NewAction: TBasicAction)

Arguments

Description

SetAction ensures that the ActionLink property is updated when the new property value is applied to the control.

When NewAction contains Nil, the class instance in ActionLink is freed and Nil'd.

Otherwise, GetActionLinkClass is called to create a new action link class instance for the ActionLink member. Its Action property is set to the value in NewAction, and its OnChange event handler is set to the DoActionChange method. ActionChange is called to synchronize property values in the class instance to the values in the Action.
