screen
The screen on which the top edge of the window’s frame is to lie.
Return Value
The adjusted frame rectangle.
Discussion
If the window is resizable and the window’s height is greater than the screen height, the rectangle’s height is adjusted to fit within the screen as well. The rectangle’s width and horizontal location are unaffected. You shouldn’t need to invoke this method yourself; it’s invoked automatically (and the modified frame is used to locate and set the size of the window) whenever a titled NSWindow
object is placed onscreen and whenever its size is changed.
Subclasses can override this method to prevent their instances from being constrained or to constrain them differently.
