- * SECTION:gtkgradient
- * @Short_description: Gradients
- * @Title: GtkGradient
- *
- * GtkGradient is a boxed type that represents a gradient.
- * It is the result of parsing a
- * [gradient expression][gtkcssprovider-gradients].
- * To obtain the gradient represented by a GtkGradient, it has to
- * be resolved with gtk_gradient_resolve(), which replaces all
- * symbolic color references by the colors they refer to (in a given
- * context) and constructs a #cairo_pattern_t value.
- *
- * It is not normally necessary to deal directly with #GtkGradients,
- * since they are mostly used behind the scenes by #GtkStyleContext and
- * #GtkCssProvider.
- *
- * #GtkGradient is deprecated. It was used internally by GTK’s CSS engine
- * to represent gradients. As its handling is not conforming to modern
- * web standards, it is not used anymore. If you want to use gradients in
- * your own code, please use Cairo directly.
