MouseDrag proc (atom)

Format
MouseDrag(over_object,src_location,over_location,src_control,over_control,params)

Description
This is called while dragging this object by pressing and holding the left mouse button over the object and moving the mouse. The over_object may be null if dragging over a stat panel or over other empty space.

Warning
Don't define this unless you need it, because it generates extra communication that is otherwise avoided. Most operations can be done through Click, DblClick, and MouseDrop. The other procedures are simply available for completeness.
