To: Richard Stellingwerff <remenic@xxxxxxxxx>
Hi,
Thanks. The API is easy but I think I'm confused by GdkColor.
The GdkColor is defined as
typedef struct {
guint32 pixel;
gunit16 red;
guint16 green;
guint16 blue;
} GdkColor;
What's purpose of GdkColor.pixel ? Why it's 32 bits instead of
16*3 = 48 bits (for RGB) ? When I try to set background color,
what value should I use for GdkColor.pixel ?
Thanks.
KC
