IsDragSource Attribute
Data Type: integer
4GL Access: RW
The IsDragSource attribute may be either TRUE or FALSE. If set to TRUE, a drag-and-drop operation may be started over the field; DragObject is the object that is transferred. If IsDragSource is FALSE, a drag-and-drop operation may not be initiated over the field.
The IsDragSource attribute is not displayed in the Property Inspector because it must be set at runtime, that is, the attribute must be set in the frame script.
