thanks,

You may want to use button groups

MATLAB: Radio Button Group not working

Hi Mo Jay,

The default Units property is 'normalized'. Your button group is outside the visible area.

GUI.fh = figure;
%Button group
GUI.tipinout_choice = uibuttongroup('Parent',GUI.fh,...
                                    'HandleVisibility','on',...
                                    'Title','Plot:',...
                                    'Units','pixels',...
                                    'Position',[50,316,151,101]);                  
            
 GUI.tipin = uicontrol(GUI.tipinout_choice,...
                       'Style','radiobutton',...
                       'String','Tip-in',...
                       'Position',[13,51,87,23],... %[13,51,87,23]
                       'HandleVisibility','on');
              
 GUI.tipout = uicontrol(GUI.tipinout_choice,...
                        'Style','radiobutton',...
                        'String','Tip-out',...
                        'Position',[13,12,87,23],...
                        'HandleVisibility','on');

Kind regards,

MATLAB: Problem to output value from custom GUI with radiobuttons

Hi Sarah,

the way how handles are assigned and used in guidata is not correct. Please refer to the documentation of guidata(). The correct workflow of assigning handles to guidata is to attach the handles to a figure.

Since you have to rewrite several parts of your code, I attached a simple example I used here, to illustrate the work flow:

function GUI_breakOP
    % 1 create figure
    GUI.fh = figure;
    
    % 2 create whatever handle you want to attach to figure GUI.fh
    GUI.h1 = uicontrol('style','Edit',...
                       'string','XX',...
                       'Units','normalized',...
                       'Position',[0.1 0.1 0.8 0.2],...
                       'backgroundcolor','c',...
                       'Tag','EditField2',...
                       'Enable','off');
        
    GUI.h2 = uicontrol('Style','PushButton',...
                       'String','Start',...
                       'Units','normalized',...
                       'Position',[0.1 0.4 0.3 0.2],...
                       'callback',{@func_compute},...
                       'Tag','StartButton',...
                       'backgroundcolor',...
                       'g','FontSize',12);
                       
    GUI.h3 = uicontrol('Style','PushButton',...
                       'String','Stop',...
                       'Units','normalized',...
                       'Position',[0.5 0.4 0.3 0.2],...
                       'callback',{@breakOP},...
                       'Tag','StopButton',...
                       'backgroundcolor',...
                       'r','FontSize',12);
    
    % 3 create own handles & flags/variables to exchange
    myHandle = guihandles(GUI.fh);  % save gui handles to struct
    myHandle.breakOP = false;       % flag for break OP

    
    % 4 attach to figure GUI.fh
    guidata(GUI.fh,myHandle);       % save structure


end
% now guidata can be used within functions called via GUI.fh
function func_compute(~,~)
    % 1 retrieve myHandle

    myHandle = guidata(gcbo);
    % 2 manipulate myHandle values

    myHandle.breakOP = false;   % flag for break OP
    % 3 save changed myHandle via guidata to figure

    guidata(gcbo,myHandle);     % save structure
    
    if ~isempty(str2num(myHandle.EditField2.String))
        a = str2num(myHandle.EditField2.String);
    else
        a = 1;
    end
    
    while 1
        myHandle = guidata(gcbo);                   % get structure

        myHandle.EditField2.String = num2str(a);    % edit field string
        pause(0.01);
        if myHandle.breakOP                         % check for break OP flag
            break;
        end
        a = a +1;
    end
    
end
function breakOP(~,~)
    % 1 retrieve myHandle
    myHandle = guidata(gcbo);   % get structure
    % 2 manipulate myHandle values
    myHandle.breakOP = true;    % change break OP flag
    % 3 save changed myHandle via guidata to figure
    guidata(gcbo,myHandle);     % save structure
end
