T:Windows.Graphics.Display.DisplayPropertiesEventHandler |
winrt delegate |
Note
The DisplayProperties type and related event handlers may be altered or unavailable for releases after Windows 8.1. Instead, use DisplayInformation.
Represents a method that handles display property events.
The object that raised the event.
We recommend that applications use a single delegate to handle most display events because in most cases the change to each display property requires that the application redraw itself. Also, many property changes result from a single mode change that affects the entire operating system.
The Direct3D 11.1 Simple Stereo 3D Sample shows how to handle system stereo changes.
