Fixed window size for Kivy programs

Question

Is there any way to keep the window size for Kivy programs fixed? Fixed in the sense its window size cannot be increased or decreased. For example, I want a Kivy program whose window size is 500x500 and the end user cannot either change the window size or turn it into fullscreen. I tried setting the height, width, minimum_height and minimum_width all with same values and still I can change window size and fullscreen it.

There is a way to configure the app to disable resizing

from kivy.config import Config
Config.set('graphics', 'resizable', False)

Also, the same way you can set the default width-height of the window.
Keep something in mind. Doing it like that in the beginning of your app, it will keep the settings only for that app. However, if you then run a Config.write(), you'll save the settings in a configuration file.

Config.set should be used before importing any other Kivy modules. Ideally, this means setting them right at the start of your main.py script. Alternatively, you can save these settings permanently using Config.set then Config.write. In this case, you will need to restart the app for the changes to take effect. Note that this approach will effect all Kivy apps system wide.
