Recently, I developed one App thorugh appdesigner. One of function I want to develop is to save all the varaibles and UI selection of current App and then recover them for the later quick setting up. However, I found it cannot directly assign 'app = app_save' (where I save 'app' as .mat file previously, then load as app_save). The only way to do this is to assigh all the variables and members of 'app' respectively, but I have too many variables and members and it is stupid to do this. I was wondering if there is a easy way to update 'app' as whole insrtead of individual members. Thanks.
%%%% in main app window%%%%%%%%%
function Revocer_app(app,app_save)
app.TopologyListBox.Value= app_save.TopologyListBox.Value; % can work
app = app_save; %does not work
end
%%%%%%%% in dialog app window%%%%%%%%%%
function RecoverHistorySetupButton_2Pushed(app, event)
Revocer_app(app.main_app1,app.main_app_save);
delete(app);
end
