Explanation:

Box 1: SettingsPanesp = null;

Box 2: sp = SettingsPane.GetForCurrentView();

Box 3: sp.CommandsRequested = OnSettingsPaneOpened; Note:

  • The SettingsPane class is a static class that enables the app to control the Settings Charm pane. The app can add or remove commands, receive a notification when the user opens the pane, or open the pane programmatically.

  • The show method displays the Settings Charm pane to the user.

  • The GetForCurrentView method gets a SettingsPane object that is associated with the current app view (that is, with CoreWindow).
