## 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.

GtkSymbolicColor is deprecated.

Creates a symbolic color pointing to a literal color.

#### Parameters

a newly created GtkSymbolicColor

Since: 3.0

### gtk_symbolic_color_new_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()`.

### gtk_symbolic_color_new_shade ()

    GtkSymbolicColor *

`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

    typedef struct _GtkSymbolicColor GtkSymbolicColor;
