Enable Windows 10 dark mode for current app.
The dark mode of Windows 10 does not support Win32 apps officially and this API makes use of private APIs to force enabling dark mode for current app.
Note that this API can only enable dark mode for window titlebars, all the views and colors are still using light color schemes. You should only use this API when developing custom-drawn apps.
Return whether this app is using a dark color scheme.
Note that on Windows the dark mode does not support Win32 apps, and this
method will always return false unless dark mode is explicitly enabled
Emitted when user has changed system color scheme preferences.
