Hi,

I am trying to pass variables from one callback function to another. I appear to be able to do this with a pushbutton callback function but not with an text callback function.

My code looks like:

%Obtains a list of preferences from a drop down menu
function edit1_Callback(hObject, eventdata, handles)
%From a function the string 'moderate' is obtained
%so the string value of the preference = moderate
handles.pref = preference
guidata(gcbo, handles);

%Now for passage to the next callback function using the text
function text1_Callback(hObject, eventdata, handles)
preference = handles.pref
%for the next computation and passage to the push button callback function
guidata(gcbo, handles);

Equally the strings could be numeric values, however I am not having any luck with either method. I have read a little about nested functions - could this be the case? If so could you lay out an example please - some of this is relatively new to me.

Thanks in advance for your help.
Christian

I think you may need to look at the help for GUIDATA. To store data, use two arguments. To retrieve data, use one.

Also, you may want to have a look at the tutorials:

Hi Mat

Thanks for this but using GUIDE do you have any other clues as to my problem. Read through the GUIDATA help and was slightly familiar with this.

Cheers
Christian
