NSButton *closeButton = [self standardWindowButton:NSWindowCloseButton];
NSView *themeFrame = [closeButton superview];

CGFloat buttonYOrigin = NSMaxY(themeFrame.frame)-34;

//Alter the button frames
NSRect closeFrame = closeButton.frame;
closeFrame.origin.y = buttonYOrigin;
closeButton.frame = closeFrame;    

/* (And do the same for the minimize and maximize buttons...) */

//Get the tracking area used by the window's theme frame view
NSArray *trackingAreas = [themeFrame trackingAreas];

if([trackingAreas count]>0) {
    NSTrackingArea *trackingArea = [trackingAreas objectAtIndex:0];

    //Alter the tracking area rectangle    
    NSRect trackingRect = [trackingArea rect];
    trackingRect.origin.y = NSMinY(closeFrame);

    //Create the new tracking area and set it on the window's theme frame view
    NSTrackingArea *newTrackingArea = [[NSTrackingArea alloc] initWithRect:trackingRect
                                                                   options:[trackingArea options]
                                                                     owner:[trackingArea owner]
                                                                  userInfo:[NSDictionary dictionary]];
    
    [themeFrame removeTrackingArea:trackingArea];
    [themeFrame addTrackingArea:newTrackingArea];
    [newTrackingArea release];
}

Well it worked with my implementation, yes. The key to it working, I found was to set the userInfo property on the tracking area to [NSDictionary dictionary].

Oh, I have tried to set userInfo to [trackingArea userInfo]. Setting userInfo to [NSDictionary dictionary] is new for me.
