Context

open class Context : GLibObject.Object, ContextProtocol

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 Context type acts as a reference-counted owner of an underlying PangoContext instance. It provides the methods that can operate on this data type through ContextProtocol conformance. Use Context as a strong reference or owner of a PangoContext instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Context instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<PangoContext>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Context instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<PangoContext>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Context instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Context instance.

    Declaration

    Swift

    @inlinable
override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op

    pointer to the underlying object

  • 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.
