Description

Gnome::Gtk4::R-Native is the interface implemented by all widgets that have their own Gnome::Gdk4::Surface.

The obvious example of a Gnome::Gtk4::R-Native is Gnome::Gtk4::Window.

Every widget that is not itself a Gnome::Gtk4::R-Native is contained in one, and you can get it with .get-native() in class Widget.

To get the surface of a Gnome::Gtk4::R-Native, use .get-surface(). It is also possible to find the Gnome::Gtk4::R-Native to which a surface belongs, with .Native.get-for-surface().Native.get-for-surface() in package Gnome::Gtk4.

In addition to a Gnome::Gdk4::Surface, a Gnome::Gtk4::R-Native also provides a Gnome::Gsk4::Renderer for rendering on that surface. To get the renderer, use .get-renderer().

Methods

get-renderer

Returns the renderer that is used for this Gnome::Gtk4::R-Native.

method get-renderer (--> N-Object )

Return value; the renderer for $self.

get-surface

Returns the surface of this Gnome::Gtk4::R-Native.

method get-surface (--> N-Object )

Return value; the surface of $self.

get-surface-transform

Retrieves the surface transform of $self.

This is the translation from $self's surface coordinates into $self's widget coordinates.

method get-surface-transform ( Num() $x, Num() $y )

• $x; (transfer ownership: full) return location for the x coordinate.

• $y; (transfer ownership: full) return location for the y coordinate.

realize

Realizes a Gnome::Gtk4::R-Native.

This should only be used by subclasses.

method realize ( )

unrealize

Unrealizes a Gnome::Gtk4::R-Native.

This should only be used by subclasses.

method unrealize ( )

Functions

get-for-surface

Finds the Gnome::Gtk4::R-Native associated with the surface.

method get-for-surface ( N-Object() $surface --> N-Object )

• $surface; a Gnome::Gdk4::Surface.

Return value; the Gnome::Gtk4::R-Native that is associated with $surface.
