554// Window constraining
555// -------------------
556//
557// To ensure that the windows are not placed under the menu bar, they
558// are typically moved by the call-back constrainFrameRect. However,
559// by overriding it, it's possible to inhibit this, leaving the window
560// in it's original position.
561//
562// It's possible to hide the menu bar. However, technically, it's only
563// possible to hide it when the application is active. To ensure that
564// this work properly, the menu bar and window constraining are
565// deferred until the application becomes active.
566//
567// Even though it's not possible to manually move a window above the
568// top of the screen, it is allowed if it's done programmatically,
569// when the menu is hidden. This allows the editable area to cover the
570// full screen height.
571//
572// Test cases
573// ----------
574//
575// Use the following extra files:
576//
577// init.el:
578// ;; Hide menu and place frame slightly above the top of the screen.
579// (setq ns-auto-hide-menu-bar t)
580// (set-frame-position (selected-frame) 0 -20)
581//
582// Test 1:
583//
584// emacs -Q -l init.el
585//
586// Result: No menu bar, and the title bar should be above the screen.
587//
588// Test 2:
589//
590// emacs -Q
591//
592// Result: Menu bar visible, frame placed immediately below the menu.
