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.
Since 3.0
gtk_symbolic_color_new_name ()
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()
.
Since 3.0
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.
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.
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
.
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.
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
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.
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 |
||
props |
GtkStyleProperties to use when resolving
named colors, or |
[allow-none] |
resolved_color |
return location for the resolved color. |
[out] |
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.
