Win32/Win64 Undo

[Handoko]

I tested win32/win64 widget set: TEdit and TMemo, and found they only support 1 level undo.

Can anyone test it on other widget sets? Carbon, QT, Cocoa, etc. Do they only support 1 level undo too, or more. Is it an LCL issue or widget set issue?

Haven't tested any of the WS.

But, take the win explorer (as representative for what Windows itself has on offer).
Edit a filename, or edit the path. Only one level of undo. (actually it then undoes the undo, so it goes undo - redo - undo - redo ...)

I don't know if there are any settings in the API....
