How to share data between two GUI ?

Problem:

1. Two GUI are created with name First.fig / First.m and Second.fig / Second.m.

2. Both GUI have two radio button namely first and second.

3. With one condition : only once GUI can be open at a time.

4. Expected output should be if second radio button is selected in First GUI then it should get reflected in second radio button of Second GUI.

This cannot work due to restriction 3. : If you can open one GUI only, you cannot share data between two GUIs.

So please explain the problem more clearly.

Hi Jan,

Thank you for your reply.

If I remove 3rd condition then, is it possible to link the both GUI's radio buttons in such a way that user can select the particular radio button in First GUI and same will get reflected in the Second GUI. (Basically, I want to sync radio button of both GUI with each other).

so if user select first radio button in First GUI it shows the same in second GUI without selecting in second GUI.

your assistant will be greatly appreciated.

function CreateGUI1
FigH = figure('Tag', 'GUI1', 'Name', 'GUI 1');
handles.Radio(1) = uicontrol('Style', 'Radiobutton', 'String', 'Radio 1', ...
                             'Position', [10, 10, 100, 30]);
handles.Radio(2) = uicontrol('Style', 'Radiobutton', 'String', 'Radio 2', ...
                           'Position', [10, 40, 100, 30]);
guidata(FigH, handles);
end

And the 2nd GUI:

function CreateGUI2
FigH = figure('Tag', 'GUI2', 'Name', 'GUI 2');
handles.Radio(1) = uicontrol('Style', 'Radiobutton', 'String', 'Radio 1', ...
                             'Position', [10, 10, 100, 30], ...
                             'Callback', {@radio, 1});
handles.Radio(2) = uicontrol('Style', 'Radiobutton', 'String', 'Radio 2', ...
                             'Position', [10, 40, 100, 30], ...
                             'Callback', {@radio, 2});
guidata(FigH, handles);
end

function radio(RadioH, EventData, Index)
% Get handle and handles struct of GUI1:
GUI1        = findobj(allchild(groot), 'flat', 'Tag', 'GUI1');
handlesGUI1 = guidata(GUI1H);
handlesGUI2 = guidata(RadioH);

if Index == 1
  handlesGUI1.Radio(1).Value = 1;  % Copy state to other GUI
  handlesGUI1.Radio(2).Value = 0;  % Copy state to other GUI
  handlesGUI2.Radio(2).Value = 0;  % Disable the other radio button
else
  handlesGUI1.Radio(2).Value = 1;
  handlesGUI1.Radio(1).Value = 0;
  handlesGUI2.Radio(1).Value = 0;
end

end
