How can I make the NSWindow setFrame: .. animated:YES] function animated down instead of up?

Question

When I call my [window setFrame: frame animated:YES] to enlarge the window it works great but it animates up and it goes behind the status bar. How can I make the window animate down instead?

Answer 1

Just decrease the y coordinate the same distance you increase the height.

CGFloat amountToIncreaseWidth = 100, amountToIncreaseHeight = 100;
NSRect oldFrame = [window frame];
oldFrame.size.width += amountToIncreaseWidth;
oldFrame.size.height += amountToIncreaseHeight;
oldFrame.origin.y -= amountToIncreaseHeight;
[window setFrame:oldFrame animated:YES];
