public class CairoContext
extends DrawContext

`GdkCairoContext` is an object representing the platform-specific
draw context.

`GdkCairoContext`s are created for a surface using
[method@Gdk.Surface.create_cairo_context], and the context
can then be used to draw on that surface.

Method Details

getClassHandler

public static ClassHandler getClassHandler()

cairoCreate

public Context cairoCreate()

Retrieves a Cairo context to be used to draw on the `GdkSurface`
of @context.

A call to [method@Gdk.DrawContext.begin_frame] with this
@context must have been done or this function will return %NULL.

The returned context is guaranteed to be valid until
[method@Gdk.DrawContext.end_frame] is called.

Returns:

a Cairo context to draw on `GdkSurface
