MythScreenStack screenStack; // Create a new MythScreenStack // Add some screens to the stack screenStack.AddScreen(new MainMenuScreen()); screenStack.AddScreen(new SettingsScreen()); screenStack.AddScreen(new PlaybackScreen()); // Show the first screen in the stack screenStack.ShowCurrentScreen();In this example, we create a new MythScreenStack and add three screens to it: a main menu screen, a settings screen, and a playback screen. We then display the first screen in the stack (the main menu screen) using the `ShowCurrentScreen()` method. This code example will likely be part of a larger MythTV application, and will make use of various other classes and functions from the MythTV library.
