I'm trying to understand how to transfer data periodically from a running m-file to update data in a GUI text edit field. I've tried viewing the GUI help topics, but I'm not finding them easy to understand. Any tips on how to do it or suggested reading would be appreciated.

I've been trying to understand that wiki, but I'm not getting anywhere. I can update data in the gui by using a push button, but can't figure out how to create an automatic update. I tried adding a setappdata line such as:

setappdata(hObject,'c',c);

to the OpeningFcn() but to no avail.

Have you actually been able to get GUI data to update automatically without a pushbutton?
