Adds a stop color to gradient.
offset for the color stop
color to use
Increases the reference count of gradient.
If gradient is resolvable, resolved_gradient will be filled in
with the resolved gradient as a cairo_pattern_t, and %TRUE will
be returned. Generally, if gradient can’t be resolved, it is
due to it being defined on top of a named color that doesn't
exist in props.
#GtkStyleProperties to use when resolving named colors
Creates a string representation for gradient that is suitable
for using in GTK CSS files.
Decreases the reference count of gradient, freeing its memory
if the reference count reaches 0.
Creates a new linear gradient along the line defined by (x0, y0) and (x1, y1). Before using the gradient a number of stop colors must be added through gtk_gradient_add_color_stop().

Creates a new radial gradient along the two circles defined by (x0, y0, radius0) and (x1, y1, radius1). Before using the gradient a number of stop colors must be added through gtk_gradient_add_color_stop().
X coordinate of the start circle

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.
