Change NSTableView alternate row colors

Question

I'm using the "Alternating Rows" option in Interface Builder to get alternating row colors on an NSTableView. Is there any way to change the colors of the alternating rows?

Answer 1

If you want to use an undocumented way, make a NSColor category and override _blueAlternatingRowColor like this:

@implementation NSColor (ColorChangingFun)

+(NSColor*)_blueAlternatingRowColor
{
    return [NSColor redColor];
}

@end

or to change both colors, override controlAlternatingRowBackgroundColors to return an array of colors you want alternated.

@implementation NSColor (ColorChangingFun)

+(NSArray*)controlAlternatingRowBackgroundColors
{
    return [NSArray arrayWithObjects:[NSColor redColor], [NSColor greenColor], nil];
}

@end
