Change string of pushbutton from radio button callback?

Hey all,

I'm trying to change the string of a pushbutton dynamically depending on which radio button is selected but my code is off and errors. It must be something really simple i'm missing. Here's my code:

% **********************************************  
% OPTION BUTTONS SELECTION..
% **********************************************  
% --- Executes when selected object is changed in uibuttongroup1.
function uibuttongroup1_SelectionChangedFcn(hObject, eventdata, handles)

% DECLARE GLOBAL VARIABLES IN FUNCTION..
global FiltX; % VARIABLE FOR WHICH FILTER OPTION IS SELECTED..

% SWITCH: CHECK WHICH RADIO BUTTON IS SELECTED..
switch get(eventdata.NewValue,'Tag');
    case 'OptPITCHDET'
        FiltX = 1;
        set(hObject.btAPPLYFT,'String','DETECT PITCHES..');
    case 'OptISOLATE'
        FiltX = 2;
        set(hObject.btAPPLYFT,'String','APPLY & LISTEN..');
    case 'OptFTNT'
        FiltX = 3;
        set(hObject.btAPPLYFT,'String','APPLY & LISTEN..');
end
% END SWITCH..
% **********************************************

Any ideas?

Thanks,

Paul..

change hObject to handles so

        set(hObject.btAPPLYFT,'String','DETECT PITCHES..');

turns to

        set(handles.btAPPLYFT,'String','DETECT PITCHES..');

Hey Joseph,

Thanks for the quick reply. I tried that too but they both give me this error:

Reference to non-existent field 'btAPPLYFT'.

Error in EPM_gui_form>uibuttongroup1_SelectionChangedFcn (line 305)
        set(handles.btAPPLYFT,'String','APPLY / LISTEN..');

btAPPLYFT is the tag of the pushbutton. Can't see why either work..

Well without seeing the rest of your code the only thing i can suggest is double check that the tag is spelled correctly and has the exact case in lettering.

Hey Joseph, hahaha it was something so simple. The actual pushbutton was incorrectly named btAPLLYFT. I didn't spot it at first. That will teach me to read, write and spell haha. Thanks :)
