ThemingEngineRef

public struct ThemingEngineRef : ThemingEngineProtocol, GWeakCapturing

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 ThemingEngineRef type acts as a lightweight Swift reference to an underlying GtkThemingEngine instance. It exposes methods that can operate on this data type through ThemingEngineProtocol conformance. Use ThemingEngineRef only as an unowned reference to an existing GtkThemingEngine instance.

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

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