Help with store data in GUI when calling a function

Hi,

I have a figure include two radio buttons and a push button. In this figure, I store all data in handles structure named 'handles'.

When I choose one of two radio buttons, either shows a new figure by calling a function named 'figure2' or a message in command window with contents 'No figure showed'.

I want to store data in 'figure2' in 'handles' structure which includes both data of figure1 and figure2. In my code, I just stored data 'figure2' in 'handles' structure. May I know how to do it?

Here is my code:

function untitled1_build
clc
clear all
close all
% --- FIGURE -------------------------------------
handles.figure1 = figure( ...
    'Tag', 'figure1', ...
    'Units', 'characters', ...
    'Position', [102.8 41.0769230769231 76 16.1538461538462], ...
    'Name', 'untitled1', ...
    'MenuBar', 'none', ...
    'NumberTitle', 'off', ...
    'Color', [0.941 0.941 0.941]);

% --- PANELS -------------------------------------
handles.uipanel3 = uibuttongroup( ...

    'Position', [9.8 6 48.2 8.53846153846154], ...
    'Title', {'Button Group'});

% --- PUSHBUTTONS -------------------------------------
handles.pushbutton2 = uicontrol( ...

    'String', {'Radio Button'});
set(handles.uipanel3 ,'selectedobject',[])
set(handles.pushbutton2,'callback',{@pb_callback,handles})

% Push button function
function pb_callback(varargin)
handles=varargin{3}
a=findobj(get(handles.uipanel3,'selectedobject'));
switch a
    case handles.radiobutton1
        figure2
    case handles.radiobutton2
        disp('No figure showed')
end

% Figure2
function figure2
% --- FIGURE -------------------------------------
%handles=varargin{3}
handles.figurenew = figure( ...
    'Tag', 'figurenew', ...
    'Units', 'pixels', ...
    'Position', [515 585 380 160], ...
    'Name', 'Figure2', ...

Thanks and please excuse for my English.

I don't really understand what the actual question is. Programming radio buttons outside of a button group is unnecessarily tedious though to ensure mutual exclusivity works correctly.

Hi Adam,

Did you mean programming the action of radio buttons? Could you please show an example how to programming radio buttons inside of a button group? I just started to learn programming with GUI. Please help to make me understand it clearly.

Thanks.

You have to first place a button group panel, and then place individual radio buttons into that group box. Then they will operate as expected where selecting one deselects all the others. Then you put all your code into the callback for the button group rather than into the callbacks for each individual radio button. For example, in this GUI tutorial/template MAGIC there is this callback.

% --- Executes when selected object is changed in grpRadButtonGroup.
function grpRadButtonGroup_SelectionChangeFcn(hObject, eventdata, handles)
% hObject    handle to the selected object in grpRadButtonGroup 
% eventdata  structure with the following fields (see UIBUTTONGROUP)
%  EventName: string 'SelectionChanged' (read only)
%  OldValue: handle of the previously selected object or empty if none was selected
%  NewValue: handle of the currently selected object
% handles    structure with handles and user data (see GUIDATA)
  switch get(eventdata.NewValue,'Tag') % Get Tag of selected object.
    case 'radOption1'
      % Code for when radiobutton1 is selected.
      txtInfo = sprintf('Option 1 is selected and the others are deselected.\n\nResults will be sorted in order of decreasing area.');
      set(handles.pnlResults, 'title', 'Results sorted by area');
    case 'radOption2'
      % Code for when radiobutton2 is selected.
      txtInfo = sprintf('Option 2 is selected and the others are deselected.\n\nResults will be sorted in order of decreasing intensity.');
      set(handles.pnlResults, 'title', 'Results sorted by intensity');
    case 'radOption3'
      % Code for when togglebutton1 is selected.
      txtInfo = sprintf('Option 3 is selected and the others are deselected.\n\nResults will be sorted in order of decreasing ECD.');
      set(handles.pnlResults, 'title', 'Results sorted by ECD');
%     case 'togglebutton2'
      % Code for when togglebutton2 is selected.
    % Continue with more cases as necessary.
    otherwise
      % Code for when there is no match.
  end
  set(handles.txtInfo, 'String', txtInfo);
  return; % from grpRadButtonGroup_SelectionChangeFcn

Thank you so much.

This is rapidly getting out of hand. Just a few simple controls and now you have hundreds of lines where you have to tediously set all kinds of properties and callbacks. It will just get worse and worse as you develop your app and make it fancier and more sophisticated. Why not just use GUIDE? http://blogs.mathworks.com/videos/category/gui-or-guide/

Thanks for your reply.

Actually, as you said my code is too long. I use 'Fig2m' app by Thomas Montagnon to convert a .fig file to .m file. So it's not too time-consuming to do it.

I use a GUI programmatic because my GUI includes one more a figure. I found it easier to make it with a programmatic GUI. I just need to set visible or invisible of the figure which will be showed.
