I was able to reproduce this behaviour at my end. Based on my observations, you can follow the mentioned workaround to stop duplication of toolbars and menus:
- Open the app in MATLAB App Designer.
- Go to 'Code View' and inspect the 'StartupFcn' or any other initialization functions for code that adds toolbars or menus. For example, you can look for lines like:
uimenu(f, 'Text', 'New Menu');
uitoolbar(f);
In case you find such code, you can either remove it or modify it to ensure it only runs once.
3. If you want to keep the tool bar and menu creation code, implement a 'flag' to ensure it executes only once:
properties (Access = private)
MenuCreated = false;
end
function startupFcn(app)
if ~app.MenuCreated
createMenuAndToolbar(app);
app.MenuCreated = true;
end
end
By following these steps, your app should no longer add duplicate toolbars and menus each time it opens.
Hope this helps!
