I was playing around with the Graphics drawing method
and I wanted to use NSRectFillListWithColors.
.....
My small problem is that it accept C-style arrays not NSArray.
What can I do?
Do exactly what the description of this function says;
void NSRectFillListWithColors(const NSRect *rects, NSColor
**colors, int count)
I used this function to draw the colortables of GIF, PNG or BMP-
imgaes and it looks something like:
NSRect rectList[256]; // long enough for a color table
NSColor *colorList[256];
rectList[0] = NSMakeRect( 0, 0, 26, 16 ); // is it flipped ?
rectList[1] = NSMakeRect( 32, 0, 26, 16 );
rectList[2] = NSMakeRect( 64, 0, 26, 16 );
colorList[0] = [NSColor blackColor];
colorList[1] = [NSColor whiteColor];
colorList[2] = [NSColor redColor];
NSRectFillListWithColors( rectList, colorList, 3 );
Good luck
Heinrich
