programmatic GUI callback function
1 view (last 30 days)
I want to access the GUI control from the call back function. how can I do this. I got the below code from Matlab help but it gives an error when executed. How can I access the slider from the call back function.
newval = num2str(hObject.Value);
disp(['Slider moved to ' newval]);

Akshata - what is the error message? Note that if you are trying to get the current value of the slider, you could try using
newval = num2str(get(hObject,'Value'));
The above assumes that the error has something to do with the current line that gets the newval.

I fyou're using a version of MATLAB < R2014b, hObject.Value won't work. That syntax is added in R2014b.
If your company/university if current on maintenance, you should be able to upgrade at no additional cost. If not, use get(hObject,'Value')
