You can create a subclass of NSView and in its drawRect: method, use

[[NSColor blackColor] set];
NSRectFill(rect);

ouch!
try this instead:
[[NSColor blackColor] set];
NSRectFill([self bounds]);
because /* where rect is the NSRect passed to the drawRect: method. */
can be anything.
Will the rectangle that is passed to a view's drawRect: method ever
extend outside the bounds of the view? I thought it was already
clipped to be within the view. If it is then you're better off using
the first code since the later code will usually be trying to (a) paint
a strict subset and (b) only paint where it's not going to be clipped
anyway.
