For example, you could use the persistent keyword or the component’s ApplicationData property (that you can access via Matlab’s builtin getappdata, setappdata functions. Then, in your callback function you can always check the new value and compare it to the persistent value that was stored in the last callback invocation.

I try to write my own UNDO function for the matlab editbox. I use the Keypresscallback but that’s a little bit to late. I need the originaltext before the keypress and the CaretPosition, SelectionStart, SelectionEnd. Do you know how to get all values before the Keypresscallback?
regards
