ContextRef

public struct ContextRef : ContextProtocol, GWeakCapturing

A PangoContext stores global information used to control the itemization process.

The information stored by PangoContext includes the fontmap used to look up fonts, and default values such as the default language, default gravity, or default font.

To obtain a PangoContext, use [methodPango.FontMap.create_context].

The ContextRef type acts as a lightweight Swift reference to an underlying PangoContext instance. It exposes methods that can operate on this data type through ContextProtocol conformance. Use ContextRef only as an unowned reference to an existing PangoContext instance.

  • ptr 
    Untyped pointer to the underlying `PangoContext` instance.

    For type-safe access, use the generated, typed pointer context_ptr property instead.

  • Creates a new `PangoContext` initialized to default values.

    This function is not particularly useful as it should always be followed by a [methodPango.Context.set_font_map] call, and the function [methodPango.FontMap.create_context] does these two steps together and hence users are recommended to use that.

    If you are using Pango as part of a higher-level system, that system may have it’s own way of create a PangoContext. For instance, the GTK toolkit has, among others, gtk_widget_get_pango_context(). Use those instead.
