Let me correct some of the previous.
The bound rectangle of the view contains the visibleRect.
And argument was also the same as the visibleRect.
The matrix was on a clip view and the clip view was on a scrollview.
And the scrollview is usually hidden when the window where the scroll
view is located opens.
When user presses a button, the scroll view scrolls at the end of the
view , then the scroll view becomes visible and it's supposed to show
its cells.
However, the trouble happened as I mentioned in the last message.

Hi,
Sorry for the previous incomplete message.
By the way, what I want to know is:
What cases make visibleRect.origin to be NSZeroPoint?
Since my matrix view didn't draw its cells, I put a log code before
and after its super view's drawRect to show the visible rectangle
like following:
@interface MyMatrix : NSMatrix
@implement MyMatrix
-(void)drawRect:(NSRect)rect
{
mynslog_1
[super drawRect:rect];
mynslog_2
}
The former log (mynslog_1) showed its origin like 300,0, for
instance, but latter (mynslog_2) did 0,0.
Actually the visibleRect was surely contained the bounds rectangle.
Would you tell me what cause it?
Any suggestion and comment would be very appreciated.
Thanks,
Noiro
