I’ve subclassed an NSView to draw an image across it. This works fine but everytime I press a button or anything else that is in the view (I have dropped a NSSearchField on top of the view in IB so it’s in the view) then lines and other artifacts apper around those objects…

I’ve just subclassed -drawRect…

• (void)drawRect:(NSRect)rect { NSImage *img = [NSImage imageNamed:@”BottomBar.tif”];

  [img drawInRect: rect
  fromRect: NSZeroRect operation: NSCompositeSourceOver fraction: 1.0]; [img release];

  NSBezierPath *path = [NSBezierPath bezierPathWithRect:rect]; [path setLineWidth:1]; [[NSColor darkGrayColor] set]; [path stroke]; }

The rect passed in represents the portion of your view that needs to be redrawn - you’re assuming it’s the whole view. You can get your whole view’s location by sending [self bounds].

The section with the path, for example, draws a gray box around the invalidated area each time. That’s not what you want.
