Description

Is an OnStartDockevent dispatcher.

DoStartDock calls any event handler attached to the OnStartDock event. When creating a component that descends from TControl, override DoStartDock to provide other responses in addition to the inherited event-handler call when the user starts a drag-and-dock operation.
