4.51.2.2. ogDisplay object
The ogDisplay object is an extension of the ogSurface object and is used for interfacing to a video display. There is a predefined variable named screen which is a pointer to a ogDisplay object. It is allocated upon startup, and deallocated during shutdown. This is provided as a convenience. The application designer may use their own variable of type ogDisplay, or derive a new object type as necessary.
New methods and virtual methods are listed here. All other parent methods are available.
