I am creating a GUI in matlab using guide. It's non-blocking (not calling uiwait). When the gui window is closed, I would like to execute some clean up code.
Is there an gui_ClosingFcn callback I should define in analogy to the gui_OpeningFcn template that guide creates for me?
Figure windows have a 'DeleteFcn' property, which defines a callback function that will run when the window is closed/deleted. You could potentially use that to do your clean-up.
Figure windows have a CloseRequestFcn property, which defines a callback function that will run when the window is closed (before deleting the window).
