Describe the feature

I'm looking for docs on the correct way to replace the entire content of the screen in a native app.

For example, the starting screen of my app may have connection details such as server, username, password etc. Filling in all of the boxes and submitting would then trigger a complete re-draw in the same window with a logging in screen, and then be replaced again with the main window.

I see documentation for pages but that seems to be primarily web oriented.

Also, would one use the same method (whatever it is) if the app was also built for the web?

Relevant code
