StyleRef

public struct StyleRef : StyleProtocol, GWeakCapturing

A GtkStyle object encapsulates the information that provides the look and feel for a widget.

> In GTK+ 3.0, GtkStyle has been deprecated and replaced by > GtkStyleContext.

Each GtkWidget has an associated GtkStyle object that is used when rendering that widget. Also, a GtkStyle holds information for the five possible widget states though not every widget supports all five states; see GtkStateType.

Usually the GtkStyle for a widget is the same as the default style that is set by GTK+ and modified the theme engine.

Usually applications should not need to use or modify the GtkStyle of their widgets.

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

  • ptr

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