Memory-managed wrapper type.

A convenience alias for Nothing :: Maybe SymbolicColor.

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

Creates a symbolic color pointing to a literal color.

Since: 3.0

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

Creates a symbolic color pointing to an unresolved named color. See styleContextLookupColor and stylePropertiesLookupColor.

Since: 3.0

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

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

Increases the reference count of color

Since: 3.0

If color is resolvable, resolvedColor 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 Nothing, resolving of named colors will fail, so if your color is or references such a color, this function will return False.

Since: 3.0

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.

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