OSX/Cocoa - NSScrollView with transparent background

Question

I can't seem to create a NSScrollView with a transparent background. Does anyone know why? here is my code:

NSScrollView *textScroll = [[NSScrollView alloc] initWithFrame:CGRectMake(212, 203, 381, 55)];
[textScroll setBackgroundColor:[NSColor clearColor]];
[view addSubview:textScroll];

Answer 1

I think in your case this should work:

[textScroll setDrawsBackground:NO];
