public abstract class DrawContext : Object

DrawContext is the base object used by contexts implementing different rendering methods, such as GLContext or VulkanContext.

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.

All known sub-classes:

Namespace: Gdk

Package: gtk4

public Display display { get; }
The Display used to create the DrawContext.
public Surface surface { get; construct; }

public void begin_frame (Region region)
Indicates that you are beginning the process of redrawing region on the this's surface.
public void end_frame ()
Ends a drawing operation started with begin_frame and makes the drawing available on screen.
public unowned Display? get_display ()
Retrieves the Display the this is created for
public unowned Region? get_frame_region ()
Retrieves the region that is currently in the process of being repainted.
public unowned Surface? get_surface ()
Retrieves the Surface used by the this.
public bool is_in_frame ()
