pub struct Native { /* private fields */ }
Expand description

Native is the interface implemented by all widgets that have their own gdk::Surface.

The obvious example of a Native is Window.

Every widget that is not itself a Native is contained in one, and you can get it with WidgetExt::native().

To get the surface of a Native, use NativeExt::surface(). It is also possible to find the Native to which a surface belongs, with for_surface().

In addition to a gdk::Surface, a Native also provides a gsk::Renderer for rendering on that surface. To get the renderer, use NativeExt::renderer().

Implements

NativeExt, WidgetExt, glib::ObjectExt, AccessibleExt, BuildableExt, ConstraintTargetExt, WidgetExtManual, AccessibleExtManual
