CtkGradient is a boxed type that represents a gradient.
It is the result of parsing a
gradient expression.
To obtain the gradient represented by a CtkGradient, it has to
be resolved with ctk_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 CtkGradients, since they are mostly used behind the scenes by CtkStyleContext and CtkCssProvider.
CtkGradient is deprecated. It was used internally by CTK’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.
CtkGradient * ctk_gradient_new_linear (gdouble x0,gdouble y0,gdouble x1,gdouble y1);
ctk_gradient_new_linear has been deprecated since version 3.8 and should not be used in newly-written code.
CtkGradient is deprecated.
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 ctk_gradient_add_color_stop().
x0 |
X coordinate of the starting point |
|
y0 |
Y coordinate of the starting point |
|
x1 |
X coordinate of the end point |
|
y1 |
Y coordinate of the end point |

CtkGradient * ctk_gradient_new_radial (gdouble x0,gdouble y0,gdouble radius0,gdouble x1,gdouble y1,gdouble radius1);
ctk_gradient_new_radial has been deprecated since version 3.8 and should not be used in newly-written code.
CtkGradient is deprecated.
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 ctk_gradient_add_color_stop().
x0 |
X coordinate of the start circle |
|
y0 |
Y coordinate of the start circle |
|
radius0 |
radius of the start circle |
|
x1 |
X coordinate of the end circle |
|
y1 |
Y coordinate of the end circle |
|
radius1 |
radius of the end circle |

ctk_gradient_ref has been deprecated since version 3.8 and should not be used in newly-written code.
CtkGradient is deprecated.

void
ctk_gradient_unref (CtkGradient *gradient);
ctk_gradient_unref has been deprecated since version 3.8 and should not be used in newly-written code.
CtkGradient is deprecated.
Decreases the reference count of gradient
, freeing its memory
if the reference count reaches 0.

gboolean ctk_gradient_resolve (CtkGradient *gradient,CtkStyleProperties *props,cairo_pattern_t **resolved_gradient);
ctk_gradient_resolve has been deprecated since version 3.8 and should not be used in newly-written code.
CtkGradient is deprecated.
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
.
