MATLAB: How to disable title of ButtonGroup

app designerMATLABuibuttongroup

I have an app I've created using App Designer. Included is a Button Group that I would like to Enable and Disable with a checkbox. So far this is pretty straightforward. I can disable everything in the ButtonGroup using set(app.ButtonGroup.children,'enable','off'); However, this disables everything except for the title of the button group. This results in a grayed out box with a black font title. How can I disable the title as well, or at least change the font color so it looks disabled?

It's worth noting that this machine doesn't have the latest version, so I can't use ButtonGroup.Enable

Hi David,

You can change the ForegroundColor property of the ButtonGroup to make it appear as disabled.

Hope this helps!

Enabled property is not valid for Button Group but valid for Button. So, app.Button.Enable = 'off' will work.

%% Create UIFigure
app.UIFigure = uifigure;
app.UIFigure.Position = [100 100 640 480];
app.UIFigure.Name = 'UI Figure';
% Create ButtonGroup
app.ButtonGroup = uibuttongroup(app.UIFigure);
app.ButtonGroup.Title = 'Button Group';
app.ButtonGroup.Position = [282 115 123 106];
% Create Button
app.Button = uiradiobutton(app.ButtonGroup);
app.Button.Enable = 'off';
app.Button.Text = 'Button';
app.Button.Position = [11 60 58 22];
app.Button.Value = true;
% Create Button2
app.Button2 = uiradiobutton(app.ButtonGroup);
app.Button2.Enable = 'off';
app.Button2.Text = 'Button2';
app.Button2.Position = [11 38 65 22];
% Create Button3
app.Button3 = uiradiobutton(app.ButtonGroup);
app.Button3.Text = 'Button3';
app.Button3.Position = [11 16 65 22];
%% Disable all buttons 
app.Button.Enable = 'off';
app.Button2.Enable = 'off';
app.Button3.Enable = 'off';

Also, Button Group has Visible property, so you can hide button group by the following.

app.ButtonGroup.Visible = 'off';

The lines I changed are marked with a %%

   function [] = test(varargin)
   N.fh=figure('units','pixels',...
      'position',[500 250 300 400],...
      'color',[0.73 0.83 0.96],...
      'menubar','none',...
      'name','Title',...
      'numbertitle','off',...
      'resize','off');
   N.bg = uibuttongroup('unit','pix',...
      'position',[15 25 270 55],...
      'title','Back Ground Color',...
      'fontsize',9,...
      'backgroundcolor',[0.73 0.83 0.96],...
      'foregroundcolor',[0.08 0.17 0.55]);
   N.blue = uicontrol(N.bg,...
      'style','rad',...
      'unit','pix',...
      'position',[15 15 50 15],...
      'string','Blue',...
      'value',1,...
      'backgroundcolor',[0.73 0.83 0.96]);
   N.green = uicontrol(N.bg,...
      'style','rad',...
      'unit','pix',...
      'position',[110 15 50 15],...
      'string','Green',...
      'value',0,...
      'backgroundcolor',[0.73 0.83 0.96]);
   N.gray = uicontrol(N.bg,...
      'style','rad',...
      'unit','pix',...
      'position',[200 15 50 15],...
      'string','Gray',...
      'value',0,...
      'backgroundcolor',[0.73 0.83 0.96]);
   set([N.blue,N.green,N.gray],'callback',{@bg_call,N})  %%1
   function [] = bg_call(varargin)
   N = varargin{3};
   switch findobj(get(N.bg,'SelectedObject'))            %%2
      case N.blue
     set(N.fh,'color',[0.73 0.83 0.96]);                 %%3


      case N.green
     set(N.fh,'color',[0.6 1 0.6]);                      %%3
      case N.gray
     set(N.fh,'color',[0.8 0.8 0.8]);                    %%3
   end

For %%1, you forgot the word 'callback' and you were trying to assign the callback to the buttongroup itself, not the buttons. The alternative would be to use the selectionchangefcn of the buttongroup.
For %%2, you used the field data2, but never assigned a field data2. Also, you do not need to use FINDOBJ here, you could replace this with varargin{1}.
For %%3, you referenced N.figure, but there was no field with this name in N. You meant N.fh.
