char* gtk_symbolic_color_to_string ( GtkSymbolicColor* color )
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.
Deprecated since: 3.8
GtkSymbolicColor is deprecated.
