Push Button help!

Hello, I am trying to make two push buttons in MATLAB in which one allows me to quit the program and the other allows me to continue running it.

This is what I have as my function:

function ButtonQuit
message = sprintf("Are you sure you would like to quit gesture recognition?");
figquit = uifigure('Position', [450 150 395 175]);
tarea = uitextarea(figquit);
tarea.Value = message;
%movegui('southeast')
%uialert(figquit,message,'Warning','Icon','warning');
     % Create a push button %left bottom width height
        btn1 = uibutton(figquit,'push',...
       'Position',[50, 20, 150, 50],...
       'ButtonPushedFcn', @(btn,event) Button1(btn1));
        btn1.Text = 'Yes, Quit';
        btn2 = uibutton(figquit,'push',...
       'Position',[250, 20, 150, 50],...
       'ButtonPushedFcn', @(btn,event) Button2(btn2));
        btn2.Text = 'No';
 
if Button1(btn1) %if btn1, confirm quit 
return;
elseif Button2(btn2) %if btn2, close window, continue gesture recognition
close(fig);
end
end

I'm not sure if something is missing or I have the wrong idea entirely.

Hi Priyana,

There is a slight change in syntax that you need to make for the ButtonPushedFcn.

Assuming that when Button 1 is pushed, nothing should happen, and when Button 2 is pushed, the figure should close, I corrected the syntax as follows :

function ButtonQuit
message = sprintf("Are you sure you would like to quit gesture recognition?");
figquit = uifigure('Position', [450 150 395 175]);
tarea = uitextarea(figquit);
tarea.Value = message;
%movegui('southeast')
%uialert(figquit,message,'Warning','Icon','warning');
     % Create a push button %left bottom width height
         btn1 = uibutton(figquit,'push',...
        'Position',[25, 20, 150, 50],...
        'ButtonPushedFcn', @(btn,event) Button1);
         btn1.Text = 'Yes, Quit';
         btn2 = uibutton(figquit,'push',...
        'Position',[225, 20, 150, 50],...
        'ButtonPushedFcn', @(btn,event) Button2);
         btn2.Text = 'No'
        
    function Button1(btn, event)
        return;
    end
    function Button2(btn, event)
        close(figquit);
    end
end

If you need an example on how to create a quit button, have a look at the following link:

Hope this helps !
