Declaration
property ObjCanUndo: Boolean;
Description
Returns True when the Undo stack contains at least one group of objects.
ObjAllClearUndo (or ObjClearUndo if there is only one group of objects) sets ObjCanUndo to False.
Note: If you are using
ObjUndoMode = ieumShared to share object and image undo, do not use
ObjCanUndo. Use
CanUndo instead.
Example
// Enable object undo
ImageEnVect1.ObjCanUndo := True;
Transition Information
If you are transitioning your code to
TImageEnView Layers, instead of ObjCanUndo, use:
TImageEnProc.CanUndo
b := ImageEnView1.Proc.CanUndo;
