class methods:

+(void)fillRect:(NSRect)rect +(void)strokeRect:(NSRect)rect +(void)clipRect:(NSRect)rect +(void)strokeLineFromPoint:(NSPoint)point1 toPoint:(NSPoint)point2

if speed is critical there here are some C functions you can call directly:

void NSRectFill(NSRect rect); void NSRectFillList(const NSRect *rects, int count); void NSRectFillListWithGrays(const NSRect *rects, const float *grays, int num); void NSRectFillListWithColors(const NSRect *rects, NSColor **colors, int num);

//drawing outlines

void NSFrameRect(NSRect rect); void NSFrameRectWithWidth(NSRect rect, float frameWidth); void NSFrameRectWithWidthUsingOperation(NSRect rect, float frameWidth, NSCompositingOperation op);
