Hi,

I might be using a slightly older version, but I hope things haven't changed much. I had two questions on the Undo capability.

1. Is it possible to pause the undo-states capturing.
I.e. I have overridden the canvas to extend its behavior, and at times there are some state changes I do programmatically, and then user interacts with the boxes and lines, and changes the state again. I would like to not capture the programmatic changes in the undo stack.

I also see a
[code] void enable(boolean enabled) { undoEnabled = enabled; }[/code]
which doesn't clear the history. Can I make that public and use it, or can you forsee any problems there?

2. Trying out the undo feature, it looked to me like applying a color to a box was not captured in the history. Are there any other such operations that aren't undoable?

Appreciate your help!

Thanks,
Praveen
