How to make sure GUI is deleted before generating it again?

1 view (last 30 days)
I have a GUIDE made gui and I'd like to make sure that the figure of the gui is deleted along with all associated data (destroyed) before generating it again? (without having to manually close the gui before calling it again) Basically I want to return the gui to it's original state (all buttons return to off position.. etc.) possibly by taking action in the 'opening function'
thanks and any help is appreciated

As far as I remember there is an "Open once only" flag in GUIDE, which include code to prevent opening multiple instances of one GUI. Please search in the menus again.
[EDITED] I've a link:, and especially Unfortunately this feature must be selected initially. But you can create a new figure with this option and copy the created code to your existing project.
Actually you only need a unique tag for the figure and close existing figures in the OpeningFcn:
figTag = 'MyUniqueFigureTag';
oldFig = findobj(allchild(0), '-flat', 'Tag', figTag);

Use delete(name of ur gui) command.
A way to do it might be to put a new push button & write above command in that push button's call-back

I want this to happen automatically when the gui is generated.. maybe by adding some command in "varargout" or "opening" -function..., not through a push button?!
