Thanks, Marco.

The reason I am subclassing NSRulerView is I want to modify what is
drawn in it. This I do in drawRect, and it works fine - this also
confirms that the custom ruler is created. Also, I want it to be
wider than the standard size. So what I first tried was to override
initWithFrame and use setFrameSize to adjust the width, but that
didn't work. The code was not even executed I noticed when stepping
through the debugger. I then tried setting the frame of myRulerView
after calling setRulerViewClass:


    MyRulerView    *ruler = [scroller verticalRulerView];
    NSRect    r = [ruler frame];
   
    r.size.width = 50;

    [ruler setFrameSize:r.size];


Again that didn't change the size, although I can see in the debugger
that the framesize has changed. How/where should I call this?

thanks again,

- Koen.
