Description

Is an OnDragDrop event dispatcher.

When creating a component that descends from TControl, override DragDrop to add additional code that executes before the OnDragDrop event handler is called.

The Source parameter is the object that was dropped onto the control. The X and Y parameters are the mouse coordinates where the object was dropped.
