Note the comment just before the function declaration: > % --- Executes on selection change in listbox1. What you would want to do is run this code in the CreateFcn for the listbox. I would in fact put all this code in a function that accepts the handle of the listbox to update and call that separate function from both the CreateFcn and the Callback function. Since you're doing this in GUIDE, you may need to change the CreateFcn property in the Property Inspector to force GUIDE to give you the prototype of the CreateFcn in your file. http://www.mathworks.com/support/solutions/en/data/1-4GA0LM/?solution=1-4GA0LM -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com

Right so its like the directory listbox example on the Mathworks website then. I would have to run the function under OpeningFcn for the gui, and specify it on its own in the code right?
From: Maxx on 29 Jun 2010 13:55 Also, I was receiving the following error message: Warning: single-selection listbox control requires that Value be an integer within String range control will not be rendered until all of its parameter values are valid. I read up on it and the solution is the set(handle,'value',1) command. However, this just returns the first item in my cell array (because its recognized as value=1). When I edit the set(h,value) in and out of the different functions it either displays the warning or goes to the first value.... Maxx

Sorry! This problem was solved in a previous post. Thanks for your help |
