MATLAB: Help with string return of a Popupmenu in GUI

Question

I have designed a pop-up menu ('xchannelmenu') with two strings 'ao0' and 'ao1' in a GUI created with GUIDE. I have set the strings using the Property Inspector -> String.

To retrieve the string chosen by the user when a specific button is pushed I am using the following code:

    xval=get(handles.xchannelmenu,'Value');
    xc=handles.xchannelmenu.String(xval);

The problem is that when the first string is selected I get the correct returned string ('ao0'), but when the second one is selected the return is:

[1x5 char]

While debugging the callback function, I have tried the command:

handles.xchannelmenu.String

which returns

ans = 
      'ao0'     
      [1x5 char]

Any idea what am I doing wrong?

Answer 1

 xc=handles.xchannelmenu.String{xval}
