Look at these -setAutoresizingMask parameters:
NSViewNotSizable
The receiver cannot be resized.
NSViewMinXMargin
The left margin between the receiver and its superview is flexible.
NSViewWidthSizable
The receiver’s width is flexible.
NSViewMaxXMargin
The right margin between the receiver and its superview is flexible.
NSViewMinYMargin
The bottom margin between the receiver and its superview is flexible.
NSViewHeightSizable
The receiver’s height is flexible.
NSViewMaxYMargin
The top margin between the receiver and its superview is flexible.
So You can do it like this:
[YourOutlet setAutoresizingMask: NSViewMinXMargin | NSViewMinYMargin];
