- TITLE : Undo in a Memo field

- Doing an UnDo in a Memo Field:
-
- If you have a pop-up menu in a TMemo, and put shortcuts
- on it for the Cut,Copy, Paste, then you can handle those
- events, and call CuttoClipBoard, CopytoClipBoard, etc.
-
- However, if you put an Undo option onto your pop-up menu
- (normally Ctrl-Z) how do you instruct the TMemo to do the Undo?
- If the built-in undo is sufficient, you can get it easier than
- a Ctrl+Z:
-
- Memo1.Perform(EM_UNDO, 0, 0);
-
- To check whether undo is available so as to enable/disable
- an undo menu item:
-
- Undo1.Enabled := Memo1.Perform(EM_CANUNDO, 0, 0) <> 0;
