RE: Window Placement

This confused me at first, too.  NSRect is a struct in Cocoa, not an object.
In fact it is a struct of structs (an origin (NSPoint) and a size (NSSize)).

Lose the * in the declaration and the java-ish setFrame argument.  Also, I'm
guessing that you want the window centered on the screen (is that what you
meant by "perfect"?).  Your "x" argument in setFrame should use width/2
rather than 500/2 if that is the case.  Like so (not tested):

NSScreen *screen = [NSScreen mainScreen];
NSRect d = [screen frame];
NSRect newRect;
newRect.size.height = 500;
newRect.size.width = 700;
newRect.origin.x = d.size.width/2 - newRect.size.width/2;
newRect.origin.y = d.size.height/2 - newRect.size.height/2;
[[winControl window] setFrame:newRect display:NO];

You could also use the NSMakeRect() function to set up the new frame.
