The foreground and background + * colors in a GC are unsigned longs. These are meant to be used as indexes + * into a table of XColors, where an XColor is declared in Xlib.h as: + * typedef struct { + * unsigned long pixel; + * unsigned short red, green, blue; + * char flags; + * char pad; + * } XColor; + * + * The xlib function XParseColor creates XColors from strings. It recognizes + * literal hexadecimal color specifications such as "#RRGGBB" as well as the + * standard X11 color names. When XParseColor creates an XColor it fills in + * all of the fields except for the pixel field, and then passes the XColor + * to TkpGetPixel to get a value to use for the pixel field. Since TkpGetPixel + * is platform specific, each platform is free to choose a value which can + * be used to set the foreground or background color in the platform's graphics + * context. + * + * Tk represents a color by a struct TkColor, which extends the XColor struct. + * Tk provides a mapping from color names to TkColors which extends the mapping + * provided by XParseColor but also allows for platform specific color names. + * By convention, these platform specific color names begin with the string + * "system". The mapping from names to TkColors is implemented by the function + * TkpGetColor defined for the Macintosh in this file. The pixel field in the + * XColor contained in a TkColor will be stored in the X11 graphics context. + * In X11 the pixel field is used as an index into a colormap.
