I have a state button which displays "connect" and when clicked creates an auxillary application. Once the application is open, the state button displays "connecting".

When the auxillary application closes, what close request callback could I write to make the state button in the main application return to its normal state of displaying "connect"?

I've read through https://uk.mathworks.com/help/matlab/creating_guis/creating-multiwindow-apps-in-app-designer.html already but had no success.

There is a closereqfcn for the secondary window. That one should have access to the handle to the object in your main window. That means you have to share at least that handle with the secondary window when you create it.

I've done that but still not working. Thank you for your help. I'm sure the solution is simple, I just can't work out how exactly to do it from the online documentation.

Does the second window have to be an AppDesigner app? If not, you can use the advice from this thread to create one from a function (using only code to create either a figure or a uifigure).
