Once a style is retrieved, a color hex value from the style can be converted to a GdkColor with

gboolean    gdk_color_parse                 (const gchar *spec,
                                             GdkColor *color);

The GdkColor is

struct GdkColor
{
  gulong  pixel;
  gushort red;
  gushort green;
  gushort blue;
};

The red, green and blue values can be divided by 65535 to get a percentage value that can then be applied to a cairo_set_source_rgba(cr, 1.0, 1.0, 1.0, 1.0) call, as in

cairo_set_source_rgba(cr, color.red/65535, color.green/65535, color.blue/65535, 1.0);

The actual colors to use should be computed from the style either when the _init() function is called (if the style is available then) or from the _expose() call. Appropriate defaults (re: white) should be used if the expected style setting is not found or is not set.

This can be tested with the pigtk app using the -T argument which will load the data/gtkrc file.

I tried to do this but couldn't get the bg[] and fg[] to get passed through correctly. I was only ever able to pass the red component of the fg color, everything else was never set correctly - or couldn't be used correctly. I never figured it out and it's just not that important for now.

So I'll move this way down the list and maybe come back to it some other time.
