PV GET DRAG SOURCE


PV GET DRAG SOURCE ( area ; source ; signatures )

Parameter	Type	Description
area	Longint	4D View area
source	Pointer	Pointer to drag source object
signatures	String array	Signatures array

Description

The PV GET DRAG SOURCE command sets the pointer source to the drag source object.

The signatures array is filled with the signatures of objects being moved. This parameter can be
used to distinguish 4D objects from other 4D View objects that have been dragged and thus execute the appropriate code during dropping. The signature of 4D objects is __OBJECT4D__ (each __ consists of two underlines). This internal signature cannot be modified. For more information, refer to the Drag and Drop, Introduction section.

Example

Refer to the example for the PV SET DRAG SIGNATURES command.
