Problem with Toggling Invisibility of Edit Text Box

I've been trying to toggle the invisibility of a text box and its labels using the state buttons in Matlab, but can't figure out why it doesn't work.
There aren't any error messages popping up, just that when I press the state button in my GUI, nothing happens.
function StateButton_Pushed(app, eventdata)
button_state = get(app.StateButton, 'Value');
if button_state == get(app.StateButton, 'Max')
set(app.StateEditFieldLabel, 'Visible', 'on');
set(app.StateEditField, 'Visible','on');
elseif button_state == get(app.StateButton, 'Min')
set(app.StateEditFieldLabel, 'Visible', 'off');
set(app.StateEditField, 'Visible','off');
end
end
Also I have the StateEditField and StateEditFieldLabel both preset to be invisible in the constructor.
What is the problem here?

drawnow updates the figure and processes the callbacks. Is there something in the eventdata that might help you determine the state of the toggle button?

With App Designer you need to look at the Object's value property as you are doing. However, it will return a logical value. If it is depressed it will return 1 (true), else it will return 0 (false).
function StateButton_Pushed(app, eventdata)
value = app.StateButton.Value;
if value % I am considering this the pressed state
set(app.StateEditFieldLabel, 'Visible', 'on');
set(app.StateEditField, 'Visible','on');
elseif ~value % I am considering this the normal state
set(app.StateEditFieldLabel, 'Visible', 'off');
set(app.StateEditField, 'Visible','off');
end
end
