AppWindow sample

This sample shows you how to work with secondary windows in your app.

AppWindows are secondary windows that run on the same thread as the CoreWindow, and they share the same core dispatcher.

Specifically, this sample shows how to:

  • Create a secondary window: Creates an AppWindow and switches to it.
  • Position a secondary window onto another display: AppWindows can be positioned, including the ability to position onto a specific display. This sample will show how to find the display your app is on, and other displays currently active in the system.
  • Setting the size of a secondary window: Sets the size and position of an AppWindow before showing it to the user.
  • Position a secondary window relative to another window in the app or a display: You can position the AppWindow relative to the upper left corner of a display, relative to the app's main view, or relative to another window in the app (not demonstrated).
  • Participating in CompactOverlay with a secondary window using AppWindow: AppWindows can be placed into view modes like regular application views. This sample shows how to place an AppWindow into CompactOverlay mode.

Note The Windows universal samples require Visual Studio to build and Windows 10 to execute.
