Matlab GUI Posted by kotsiostill yesterday at 7:45 AM
I have created a GUI and there is a pop-up menu in it. I want to know how I can generate an error dialogue when the pop-up menu is not open/used by a user. For the edit box, I use "isempty", but that doesn't work for the pop-up menu.

Thanks and I look forward to hearing your solution.
