I have confused about GdkColor In general,the RGB color mode ,the red or green or blue's value is from 0 to 255 But ,the GdkColor ,the value is from 0 to 65535 My question is ,how to map (0--255) to (0--65535) For example ,i have a general color (245,222,179) map it to GdkColor ,what is the value ? At any time ,your advice for gtk or English is welcome!
