I would like to have a way to query the current depth of the undo and redo stacks of a text widget. This would allow to enable/disable contextually Undo and Redo commands in applications. Whether the undo stack is empty or not can be known by querying the modified flag (although this is not equivalent, but I can set the modified flag manually in such a way that it is). I have however no solution for the redo stack depth. How can I know if it's zero or not? Currently I have to track manually any editing in my text widget, this is cumbersome and greatly lowers the interest of using the embedded .text edit commands. In summary please add a command that gives the current depth of each stack, or at least a command that says if the depths are zero or not. Thanks, Francois
