Re: Creating subviews programmatically ?

Sorry, I was using Bounds instead of Frame...  but it still doesn't 
change the behavior with the array. Here are the two methods I'm using:

/* Changing frame (which is what happens when the window is resized) 
should cause relayout.
  */
- (void)setFrameSize:(NSSize)size {
    [super setFrameSize:size];
    [self resizeDayViews: size];
}


-(void)resizeDayViews: (NSSize) size  //  Adjust all subViews for size 
of Main view
{
   NSArray *subDayViews = [self subviews];  // get array of all subviews
   NSEnumerator *enumerator = [subDayViews objectEnumerator]; // get 
enumerator to step through the subview array
   
   NSRect newFrame = [self frame];            // get current bounds rect
   NSRect newRect;
   
   
   float dayWidth = ( (newFrame.size.width - 9) / 7);
   float weekHeight = ( (newFrame.size.height - 9) / 6) ;
   int x,y,rowCnt, columnCnt;
   
   NSLog( @"Start of Resize Method------------------------------");

   // for each row of days
   for (y = 5, rowCnt = 0;  rowCnt < 6;    y = y + weekHeight, rowCnt++)
   {
       for(x = 5, columnCnt = 0; columnCnt < 7; x = x + dayWidth, columnCnt+
+)
       {
           newRect = NSMakeRect(x, y, dayWidth, weekHeight );
           DayView *tempView = [enumerator nextObject];
           [ tempView setFrame: newRect ];
           NSLog( @"frame set");
           NSLog( @"%@", [NSString stringWithFormat:@"%i", [tempView 
gridNum] ]);
           NSLog(@"%@", NSStringFromRect(newRect) );
           
           NSLog(@"%@", NSStringFromRect([ tempView frame]) );
       }
       
   }
}
