ButtonGroup

Hi guys.

How can I run it?

"

 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.bg,{@bg_call,N})

 function [] = bg_call(varargin)
 N = varargin{3};
 switch findobj(get(N.data2,'SelectedObject'))
    case N.blue
   set(N.figure,'color',[0.73 0.83 0.96]);
    case N.green
   set(N.figure,'color',[0.6 1 0.6]);
    case N.gray
   set(N.figure,'color',[0.8 0.8 0.8]);

 end

colors will change only with buttongrup.

(don't guide editor, just .m)

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

1. 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.
2. 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}.
3. For %%3, you referenced N.figure, but there was no field with this name in N. You meant N.fh.
