Method

GskRendererrealize

Declaration [src]

gboolean
gsk_renderer_realize (
  GskRenderer* renderer,
  GdkSurface* surface,
  GError** error
)

Description [src]

Creates the resources needed by the renderer to render the scene graph.

Since GTK 4.6, the surface may be NULL, which allows using renderers without having to create a surface.

Note that it is mandatory to call gsk_renderer_unrealize() before destroying the renderer.

Parameters

surface

Type: GdkSurface

The GdkSurface renderer will be used on.

The argument can be NULL.
The data is owned by the caller of the function.
error

Type: GError **

The return location for an error.

The argument can be NULL.
The argument will be set to NULL by the function if there are no errors.
In case of error, the argument will be set and the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

Whether the renderer was successfully realized.
