MATLAB: UI push buttons play audio

pushbuttons

Hello, I need to build a UI with 3 push buttons and each one of them needs to play an audio file. I am not used to working with UI and the code that I would use within a script doesn't work for the UI. Any tips on how to do it please? 🙂 Cheers!

if you want to create your ui programmatically, check this out:

https://www.mathworks.com/help/matlab/ref/uicontrol.html

if you want to use matlabs appdesigner, which is actually pretty nice but you dont have complete control:

https://www.mathworks.com/help/matlab/creating_guis/create-a-simple-app-or-gui-using-app-designer.html

I prefer programming the ui myself.

so for example to create a pushbutton:

%in a script:
f = figure;
push1 = uicontrol('Style','pushbutton',... %type of uicontrol
    'String','Enter',...
    'callback',@push1callback); %run this function when triggered / pushed
push1 %call this to see other properties you can adjust.
%create a function for the pushbutton:
function push1callback(hObj,event) %always include these 2 parameters, they are there by default
disp('hello')
end

MATLAB: Appdesigner button group problem

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';

Set its 'Value' to true and call its 'Callback' to the toggle button's callback:

function exampleTGL
%SCd
      hFig = figure;
      hPush = uicontrol('Style','pushbutton',...
            'Units','normalized',...
            'Position',[0.1 0.1 0.3 0.5],...
            'String','Push Me!',...
            'Callback',@Push);  
      hTog = uicontrol('Style','togglebutton',...
            'Units','normalized',...
            'Position',[0.5 0.1 0.3 0.5],...
            'String','Toggle',...
            'Callback',@tog);  
      function Push(src,evt)
          set(hTog,'Value',true);
          tog(hTog);
      end
      function tog(src,evt)
          disp 'toggled'
      end
end
