GdkDrawingContext

Description [src] 

final class Gdk.DrawingContext : GObject.Object
{
  /* No available fields */
}

GdkDrawingContext is an object that represents the current drawing state of a GdkWindow.

It’s possible to use a GdkDrawingContext to draw on a GdkWindow via rendering API like Cairo or OpenGL.

A GdkDrawingContext can only be created by calling gdk_window_begin_draw_frame() and will be valid until a call to gdk_window_end_draw_frame().

GdkDrawingContext is available since GDK 3.22
