I want to add 3 toggle buttons to the toolbar. They are exclusive, i.e., only one of them should be pressed.

It is easy to create these buttons on a figure by using uibuttongroup, which takes care of the desired behavior. Is it possible to add them to the toolbar?

Hello Xi,

From my understanding, you want to add 3 toggle buttons to the toolbar and you want only one toggle button being active at the same time.

You can make use of 'uitoggletool' to create a toggle button on toolbar and create appropriate callbacks for toggle action to set the state of other toggle buttons

For example

function createToggleButtons
f = figure('ToolBar','none');
tb = uitoolbar(f);
img = zeros(16,16,3);
% Create 2 toolbar items (set one among them to have ‘on’ State)      
tb1 =uitoggletool(tb,'CData',img,'TooltipString','ToggleButton1','State','on');
tb2=uitoggletool(tb,'CData',img,'TooltipString','ToggleButton2');
  % Set the callback for each toggle passing itself and the other toggle
  %  to the callback
  set(tb1,'ClickedCallback',@(obj,event)ToggleToolbar(obj,tb2));
  set(tb2,'ClickedCallback',@(obj,event)ToggleToolbar(obj,tb1));
end
function ToggleToolbar ( primary, secondary )
  % Switch the other toolbar state based on the value of the 
  %   toolbar which the user clicked on.
  switch get ( primary, 'State' )
    case 'on'
      set ( secondary, 'State', 'off' );
    case 'off'
      set ( secondary, 'State', 'on' );
  end
end

Although I'm seeking solutions by taking advantages of the "uibuttongroup", your solution is simpler than what I thought, especially the idea of using one shared callbackfunction.

If I have more than two toggle buttons, I can simply use "findobj" to set the states of all togglebuttons 'off' and turn on the current one.

Thx!
