public abstract class DrawContext : Object

Base class for objects implementing different rendering methods.

`GdkDrawContext` is the base object used by contexts implementing different rendering methods, such as [class@Gdk.CairoContext] or [ class@Gdk.GLContext]. It provides shared functionality between those contexts.

You will always interact with one of those subclasses.

A `GdkDrawContext` is always associated with a single toplevel surface.
