<sel>drawRect:</sel>
<arg type="NSRect">aRect</arg>
<desc>
This method is invoked to handle drawing inside the view.
The default NSView's implementation does nothing;
subclasses might override it to draw something inside the
view. Since NSView's implementation is guaranteed to be
empty, you should not call super's implementation when you
override it in subclasses. drawRect: is invoked when the
focus has already been locked on the view; you can use
arbitrary postscript functions in drawRect: to draw inside
your view; the coordinate system in which you draw is the
view's own coordinate system (this means for example that
you should refer to the rectangle covered by the view
using its bounds, and not its frame). The argument of
drawRect: is the rectangle which needs to be redrawn. In
a lossy implementation, you can ignore the argument and
redraw the whole view; if you are aiming at performance,
you may want to redraw only what is inside the rectangle
which needs to be redrawn; this usually improves drawing
performance considerably.
