Gdk.Surface
Description: Reference for Gdk.Surface

### Class

# GdkSurface

#### Description [src]

    abstract class Gdk.Surface : GObject.Object
    {
      /* No available fields */
    }

Represents a rectangular region on the screen.

It’s a low-level object, used to implement high-level objects such as GtkWindow.

The surfaces you see in practice are either `GdkToplevel` or `GdkPopup`, and those interfaces provide much of the required API to interact with these surfaces. Other, more specialized surface types exist, but you will rarely interact with them directly.
