DrawContext

abstract class DrawContext(val gdkDrawContextPointer: <Error class: unknown class><<Error class: unknown class>>)(source)

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.
