- (void)drawRect:(NSRect)rect
{
[[NSColor controlColor] set];
NSRectFill(rect);
[self drawHashMarksAndLabelsInRect:rect];
[self drawMarkersInRect:rect];
}
This works for me (with [NSColor whiteColor] to get a white background
for
the rulers - the user might want to actually read the ruler
rather than look at the nice stripes).
But... I don't use any scrollbars. I have a hand tool to do the
scrolling and the only reason I have a scroll view is to get the
rulers. My view isn't completely hooked up. I want to scroll
by copying pixels and I couldn't get the advertised methods
to work if the scroll wasn't exactly horizontal or vertical.
A printf in my view's drawRect showed the entire rect was
being redrawn (twice) for each mouse drag event. So I do
things myself, including moving the ruler origins.
Also - I have no NSRulerMarkers - just a moving hash mark
following the cursor drawn with
moveRulerlineFromLocation:toLoaction:
Try putting a breakpoint in your drawRect method and see how often
it is called and what is going on at the time.
