Hi Eyal,
I understand that the "CloseRequestFcn" which is properly triggered when running an app in MATLAB, does not get triggered when the app is deployed as a web app and closed in the browser.
It is a documented limitation that the "CloseRequestFcn" property has not effect in web apps:
As a potential workaround, you can register a "DeleteFcn" callback for your "uifigure", which will be called whenever the web app is closed. To do this, add the following line to "startupFcn":
app.UIFigure.DeleteFcn = createCallbackFcn(app, @deleteFcn, true);
and then create a function called "deleteFcn" in your app like this:
function deleteFcn(app, event)
% put your logic here that would otherwise be in CloseRequestFcn
end
I hope this workaround helps!
Best regards,
Sreeram
