How to use toogle button to switch on and off a push button?

when i push the toggle button, it displays on and off but I want that when I pressed the toggle switch to on, the "add" pushbutton will execute. I'm thinking of adding a while loop to the code of "add" button but i dont know how. I want my add button executes only when the toggle button is on.

here's my code:

% --- Executes on button press in add.
function add_Callback(hObject, eventdata, handles)
% hObject    handle to add (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA);
persistent add
count=handles.count;
if isempty(add)
    add=count;
    add=add+1;
else
    add=add+1;
end
handles.add=add;
set(handles.screen,'String',add);
guidata(hObject, handles);


% --- Executes on button press in on_offbutton.
function on_offbutton_Callback(hObject, eventdata, handles)
% hObject    handle to on_offbutton (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hint: get(hObject,'Value') returns toggle state of on_offbutton
button_state = get(hObject,'Value');
if(button_state == 1)
   set(handles.on_offbutton,'String','ON','ForegroundColor','green')

else
    set(handles.on_offbutton,'string','OFF','foregroundcolor','red')
   
end

If I understand correctly, you have a toggle button and a pushbutton. When you set the toggle button to 'on', you want the pushbutton callback to execute. Is that correct?

If that is correct, the trick is perhaps to realize that your callbacks are just functions. You can call them just like any function. The solution here is to call the pushbutton callback from within the toggle callback function (when value is 'on'). Just be sure to set the first input to be the corresponding component object instead of hObject.

% --- Executes on button press in on_offbutton.
function on_offbutton_Callback(hObject, eventdata, handles)
% hObject    handle to on_offbutton (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% Hint: get(hObject,'Value') returns toggle state of on_offbutton
button_state = get(hObject,'Value');
if(button_state == 1)
   set(handles.on_offbutton,'String','ON','ForegroundColor','green')
   % Call the add callback function.
   add_Callback(handles.add_callback, eventdata, handles)
else
    set(handles.on_offbutton,'string','OFF','foregroundcolor','red')   
end

Thank you it works but i also want it to stop when i switch the toggle button to off. how will i do that?

[Cris LaPierre]

You want it to stop doing what?

[Sofia Ventura]

When I switch the toggle button to "off" i want it to stop adding when i press the add button.

[Cris LaPierre]

When you push the Add button, it will call the add_Callback function.

There are a couple options for how I might approach this

1. Use the toggle button to set the 'Enable' property of the Add button 'on' and 'off' or
2. Add a condition to your add callback to only execute if the toggle switch is on.
