Hi,
I can enable/disable an undo button for a Text widget depending on
Text.edit_modified(); i.e., if it is modified then I can safely call
undo.
But what I'd really like to do is just check the undo *and redo* stacks
to see whether they are empty and enable/disable based on that.
Is this possible?
Thanks!
