I may be mistaken, but I believe that you can achive this without
writing code, I think that this is called the widget's "PRELIGHT" state
and you can assign this in the gtkrc file like so:

style "some_kinda_font_style"
{
        font_name       =       "Arial bold 14"
        fg[NORMAL]      =       { 0.000, 0.000, 0.000 }
        fg[ACTIVE]      =       { 0.063, 0.443, 1.000 }
        fg[PRELIGHT]    =       { 0.000, 0.000, 0.000 }
        fg[SELECTED]    =       { 0.000, 0.000, 0.000 }
        fg[INSENSITIVE] =       { 0.000, 0.000, 0.000 }
}

HTH,
