ThemingEngine

open class ThemingEngine : GLibObject.Object, ThemingEngineProtocol

GtkThemingEngine was the object used for rendering themed content in GTK+ widgets. It used to allow overriding GTK+‘s default implementation of rendering functions by allowing engines to be loaded as modules.

GtkThemingEngine has been deprecated in GTK+ 3.14 and will be ignored for rendering. The advancements in CSS theming are good enough to allow themers to achieve their goals without the need to modify source code.

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

    Declaration

    Swift

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

    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 ThemingEngine instance.

    Declaration

    Swift

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

    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 ThemingEngine instance.

    Declaration

    Swift

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

    Parameters

    op

    gpointer to the underlying object
