Radio buttons in GUI

HI,

I have two radio buttons in GUI. I want to make that only one button can be pressed at a time. what is the best way do it?

thanks,

[Andy]

A Button Group panel is the best way make button selections exclusive. Here is a tutorial on how to do it: https://codemusician.wordpress.com/2013/03/15/gui-tutorial-how-to-create-and-use-radio-button-groups-in-matlab/

You may want to use button groups

I prefer to control this manually:

handles.FigureH = figure;
handles.radio(1) = uicontrol('Style', 'radiobutton', ...
                           'Callback', @myRadio, ...
                           'Units',    'pixels', ...
                           'Position', [10, 10, 80, 22], ...
                           'String',   'radio 1', ...
                           'Value',    1);
handles.radio(2) = uicontrol('Style', 'radiobutton', ...
                           'Callback', @myRadio, ...
                           'Units',    'pixels', ...
                           'Position', [10, 40, 80, 22], ...
                           'String',   'radio 2', ...
                           'Value',    0);
...
guidata(handles.FigureH, handles);

And the callback:

function myRadio(RadioH, EventData)
handles = guidata(RadioH);
otherRadio = handles.radio(handles.radio ~= RadioH);
set(otherRadio, 'Value', 0);

Thank you, very helpful.

 I created uibuttongroup following your suggestions as follows:

% Create the button group. h = uibuttongroup('visible','off', 'Units', 'pixels','Position',[100 717 301 151]); handles.h = h; % Create three radio buttons in the button group. u0 = uicontrol('Style','Radio','String','Analog_Input',... 'pos',[19 75 137 52],'parent',h,'HandleVisibility','off'); u1 = uicontrol('Style','Radio','String','Function_input',... 'pos',[19 31 131 57],'parent',h,'HandleVisibility','off');

% Initialize some button group properties.

set(h,'SelectedObject',[]); % No selection set(h,'Visible','on');

I don't have any Callback. And it doesn't work - any suggestion where the problem might be?

by saying doesn't work, I get multiple selection.

The following code worked well for me, I cannot get multiple selection.

h = uibuttongroup('Units', 'pixels'); 
% Create three radio buttons in the button group. 
u0 = uicontrol('Style','Radio','String','Analog_Input',... 
    'pos',[19 75 137 52],'parent',h,'HandleVisibility','off'); 
u1 = uicontrol('Style','Radio','String','Function_input',... 
    'pos',[19 31 131 57],'parent',h,'HandleVisibility','off');
