|

* @Short_description: Gradients
|
||||
* @Title: GtkGradient
|
||||
*
|
||||
* GtkGradient is a boxed type that represents a gradient.
|
||||
* It is the result of parsing a
|
||||
* <link linkend="gtkcssprovider-gradients">gradient expression</link>.
|
||||
* 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.

* @Short_description: Symbolic colors
|

* @Title: GtkSymbolicColor
|
||||
*
|
||||
* GtkSymbolicColor is a boxed type that represents a symbolic color.
|
||||
* It is the result of parsing a
|
||||
* <link linkend="gtkcssprovider-symbolic-colors">color expression</link>.
|
||||
* To obtain the color represented by a GtkSymbolicColor, it has to
|
||||
* be resolved with gtk_symbolic_color_resolve(), which replaces all
|
||||
* symbolic color references by the colors they refer to (in a given
|
||||
* context) and evaluates mix, shade and other expressions, resulting
|
||||
* in a #GdkRGBA value.
|
||||
*
|
||||
* It is not normally necessary to deal directly with #GtkSymbolicColors,
|
||||
* since they are mostly used behind the scenes by #GtkStyleContext and
|
||||
* #GtkCssProvider.
|
||||
*
|
||||
* #GtkSymbolicColor is deprecated. Symbolic colors are considered an
|
||||
* implementation detail of GTK+.
