gtk_gradient_new_linear ()

GtkGradient *
gtk_gradient_new_linear (gdouble x0,
                         gdouble y0,
                         gdouble x1,
                         gdouble y1);

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().

Since: 3.0

gtk_gradient_new_radial ()

GtkGradient *
gtk_gradient_new_radial (gdouble x0,
                         gdouble y0,
                         gdouble radius0,
                         gdouble x1,
                         gdouble y1,
                         gdouble radius1);

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().

Since: 3.0

gtk_gradient_add_color_stop ()

void
gtk_gradient_add_color_stop (GtkGradient *gradient,
                             gdouble offset,
                             GtkSymbolicColor *color);

Adds a stop color to gradient .

Since: 3.0

gtk_gradient_ref ()

GtkGradient *
gtk_gradient_ref (GtkGradient *gradient);

Increases the reference count of gradient .

Since: 3.0

gtk_gradient_unref ()

void
gtk_gradient_unref (GtkGradient *gradient);

Decreases the reference count of gradient , freeing its memory if the reference count reaches 0.

Since: 3.0

gtk_gradient_resolve ()

gboolean
gtk_gradient_resolve (GtkGradient *gradient,
                      GtkStyleProperties *props,
                      cairo_pattern_t **resolved_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 .

Since: 3.0

gtk_gradient_resolve_for_context ()

cairo_pattern_t *
gtk_gradient_resolve_for_context (GtkGradient *gradient,
                                  GtkStyleContext *context);

gtk_gradient_to_string ()

char *
gtk_gradient_to_string (GtkGradient *gradient);

Creates a string representation for gradient that is suitable for using in GTK CSS files.
