Not really - that part's easy enough with
[newWindow setStyleMask:[newWindow styleMask] |
NSTexturedBackgroundWindowMask];
[newWindow setAutorecalculatesContentBorderThickness:NO
forEdge:NSMaxYEdge];
[[newWindow toolbar] setShowsBaselineSeparator:NO];

Now *that's* trickery. My tabView is in the window's contentView, no need to
poke around in the theme view:
NSRect tabFrame = [tabView bounds];
NSWindow *window = [tabView window];
/*
* Make the border extend to just below the top of the contentFrame.
* This will draw a line and will be where the sheet appears.
* If we don't set it, we'll get a random one.
*/
NSRect windowRect = [[window contentView] bounds];
CGFloat delta = windowRect.size.height - tabFrame.size.height + 2;
[window setContentBorderThickness:delta forEdge:NSMaxYEdge];
