GI.Gtk.Structs.Gradient

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.
