Lamps in Matlab App Desinger

Hello.

I am trying to do something simple i.e. to change the lamp color whenever the switch is pressed.

The app has multiple components i.e. groups as seen in the screen shot

I am using the following callback function for the switch.

% Value changed function: Switch2

function Switch2ValueChanged(app, event)

value_S2 = app.Switch2.Value;

if strcmp(value_S2,'On')

app.Lamp.Color='g';

else

app.Lamp.Color='r';

end

end

The problem is , whenever a run the app and press the switch, it becomes red and doesnt change its color to green.

Your code looks fine to me. A simple test app also works for me. Note that you want your lamp to turn green when it is turned on. By default, the lamp color is green to start with, and the switch by default is off. You can change the default setting of one to get the behavior you want.

I attached my test app.
