ObjChangePathEdit Class Reference

A derived change parameter for use in path editing. It is exactly the same as ObjChangeParam apart from providing a path pointer, for use during eor drags, to describe the current state of the dragged path. Obviously this cannot be determined from the tree object until it has been updated when the drag finishes. More...

Detailed Description

A derived change parameter for use in path editing. It is exactly the same as ObjChangeParam apart from providing a path pointer, for use during eor drags, to describe the current state of the dragged path. Obviously this cannot be determined from the tree object until it has been updated when the drag finishes.
