GtkSymbolicColor

GtkSymbolicColor — Symbolic colors

Types and Values

Includes

#include <gtk/gtk.h>

Description

GtkSymbolicColor is a boxed type that represents a symbolic color. It is the result of parsing a color expression. 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+.

Functions

gtk_symbolic_color_new_literal ()

GtkSymbolicColor *
gtk_symbolic_color_new_literal (const GdkRGBA *color);

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

Parameters

color

a GdkRGBA

 

Returns

a newly created GtkSymbolicColor

gtk_symbolic_color_new_name (const gchar *name);

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

GtkSymbolicColor is deprecated.

Creates a symbolic color pointing to an unresolved named color. See gtk_style_context_lookup_color() and gtk_style_properties_lookup_color().

Parameters

gtk_symbolic_color_new_shade ()

GtkSymbolicColor *
gtk_symbolic_color_new_shade (GtkSymbolicColor *color,
                              gdouble factor);

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

GtkSymbolicColor is deprecated.

Creates a symbolic color defined as a shade of another color. A factor > 1.0 would resolve to a brighter color, while < 1.0 would resolve to a darker color.

[constructor]

Parameters

color

another GtkSymbolicColor

 

factor

shading factor to apply to color

 

Returns

A newly created GtkSymbolicColor

Since: 3.0


gtk_symbolic_color_new_alpha ()

GtkSymbolicColor *
gtk_symbolic_color_new_alpha (GtkSymbolicColor *color,
                              gdouble factor);

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

GtkSymbolicColor is deprecated.

Creates a symbolic color by modifying the relative alpha value of color . A factor < 1.0 would resolve to a more transparent color, while > 1.0 would resolve to a more opaque color.

[constructor]

Parameters

color

another GtkSymbolicColor

 

factor

factor to apply to color alpha

 

Returns

A newly created GtkSymbolicColor

Since: 3.0


gtk_symbolic_color_new_mix ()

GtkSymbolicColor *
gtk_symbolic_color_new_mix (GtkSymbolicColor *color1,
                            GtkSymbolicColor *color2,
                            gdouble factor);

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

GtkSymbolicColor is deprecated.

Creates a symbolic color defined as a mix of another two colors. a mix factor of 0 would resolve to color1 , while a factor of 1 would resolve to color2 .

[constructor]

Parameters

color1

color to mix

 

color2

another color to mix

 

factor

mix factor

 

Returns

A newly created GtkSymbolicColor

Since: 3.0


gtk_symbolic_color_new_win32 ()

GtkSymbolicColor *
gtk_symbolic_color_new_win32 (const gchar *theme_class,
                              gint id);

gtk_symbolic_color_new_win32 has been deprecated since version 3.8 and should not be used in newly-written code.

GtkSymbolicColor is deprecated.

Creates a symbolic color based on the current win32 theme.

Note that while this call is available on all platforms the actual value returned is not reliable on non-win32 platforms.

[constructor]

Parameters

theme_class

The theme class to pull color from

 

id

The color id

 

Returns

A newly created GtkSymbolicColor

Since: 3.4


gtk_symbolic_color_ref ()

GtkSymbolicColor *
gtk_symbolic_color_ref (GtkSymbolicColor *color);

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

GtkSymbolicColor is deprecated.

Increases the reference count of color

Parameters

color

a GtkSymbolicColor

 

Returns

the same color

Since: 3.0


gtk_symbolic_color_unref ()

void
gtk_symbolic_color_unref (GtkSymbolicColor *color);

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

GtkSymbolicColor is deprecated.

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

Parameters

color

a GtkSymbolicColor

 

Since: 3.0


gtk_symbolic_color_resolve ()

gboolean
gtk_symbolic_color_resolve (GtkSymbolicColor *color,
                            GtkStyleProperties *props,
                            GdkRGBA *resolved_color);

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

GtkSymbolicColor is deprecated.

If color is resolvable, resolved_color will be filled in with the resolved color, and TRUE will be returned. Generally, if color can’t be resolved, it is due to it being defined on top of a named color that doesn’t exist in props .

When props is NULL, resolving of named colors will fail, so if your color is or references such a color, this function will return FALSE.

Parameters

color

a GtkSymbolicColor

 

props

GtkStyleProperties to use when resolving named colors, or NULL.

[allow-none]

resolved_color

return location for the resolved color.

[out]

Returns

TRUE if the color has been resolved

Since: 3.0


gtk_symbolic_color_to_string ()

char *
gtk_symbolic_color_to_string (GtkSymbolicColor *color);

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

GtkSymbolicColor is deprecated.

Converts the given color to a string representation. This is useful both for debugging and for serialization of strings. The format of the string may change between different versions of GTK, but it is guaranteed that the GTK css parser is able to read the string and create the same symbolic color from it.

Parameters

color

color to convert to a string

 

Returns

a new string representing color

Types and Values

GtkSymbolicColor
