NSTableView, rows in reverse order

[Marko Riedel]

Hi all,

I've come across something where I'm not sure if it's a bug or a feature.

The following code fragment draws an existing tableview into a bitmap, for 
later export as TIFF and conversion to PostScript.

  NSRect box = [table bounds], 
    hbox = [[table headerView] bounds];

  NSRect winrect = box;
  winrect.size.height += hbox.size.height;

  NSWindow *win =
    [[NSWindow alloc] 
      initWithContentRect:winrect
      styleMask:0
      backing:NSBackingStoreRetained
      defer:NO];

  [[win contentView] lockFocus];

  [table drawRect:box];

  [NSGraphicsContext saveGraphicsState];

  PStranslate(0, box.size.height);
  [[table headerView] drawRect:hbox];

  [NSGraphicsContext restoreGraphicsState];

  NSBitmapImageRep 
    *boxRep = [NSBitmapImageRep alloc];
  [boxRep 
    initWithFocusedViewRect:[[win contentView] bounds]];
  AUTORELEASE(boxRep);
    
  [[win contentView] unlockFocus];

I guess I could replace the last "[[win contentView] bounds]" with "winrect" 
but that's not relevant here.

The phenomenon I'm observing is that the tableview draws the rows in reverse 
order, from bottom to top instead of from top to bottom. So the output does not 
match what the user sees on screen. The row that comes first on screen is drawn 
last in the bitmap.

Curious, to say the least.

Best regards,

Marko
