Module Name:
|
|
- NonClientIslandWindow.h
|
|
|
|
Abstract:
|
|
- This class represents a window hosting two XAML Islands. One is in the client
|
|
area of the window, as it is in the base IslandWindow class. The second is in
|
|
the titlebar of the window, in the "non-client" area of the window. This
|
|
enables an app to place xaml content in the titlebar.
|
|
- Placing content in the frame is enabled with DwmExtendFrameIntoClientArea. See
|
|
https://docs.microsoft.com/en-us/windows/desktop/dwm/customframe
|
|
for information on how this is done.
