Hi Folks:
Getting back into GUIDE and I'm trying to figure out how to update button properties. Say I click on a radio button that represents a user option, then I would like to change the text color of another button (say from grey to black), and enable that button (make it active). Any thoughts? I can update the radio button properties, but I can't figure how to get the other button's properties to update within the radio button callback.

Much appreciated

Dave Muench:
It's easy. Just refer to it by it's full handle tag. So in the radio
button callback, you'd put this

set(handle.btnGo, 'String', 'Process files with the XXXXXX option');

which will set the text on the btnGo button to what I said.

Or something similar with the other controls.
set(handles.sldScrollBar, 'Value', 10);
etc.
The key thing is to use the full name of the tag of the control you
want to affect after the set(.

Good luck,
ImageAnalyst

Thanks ImageAnalyst. For some reason your suggestion works when updating the string property, but how about updating something like the text color, via the 'ForegroundColor' property? That is what I'm struggling with at the moment. For example:

function dynEventsFileButton_Callback(hObject, eventdata, handles)
% hObject handle to dynEventsFileButton (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)

% the line below works fine for the dynEventsFileButton:
set(handles.dynEventsFileButton,'ForegroundColor', [1 0 0]);

%And the line below will change the string for pushbutton2
set(handles.pushbutton2,'String','TestChange');
%However, the line below will not change the pushbutton foreground color
set(handles.pushbutton2,'ForegroundColor',[1 0 0]);

Is there a distinction I must make amongst various button properties? Thanks again,
Dave
