514 // are typically moved by the call-back constrainFrameRect. However,
515 // by overriding it, it's possible to inhibit this, leaving the window
516 // in it's original position.
517 //
518 // It's possible to hide the menu bar. However, technically, it's only
519 // possible to hide it when the application is active. To ensure that
520 // this work properly, the menu bar and window constraining are
521 // deferred until the application becomes active.
522 //
523 // Even though it's not possible to manually move a window above the
524 // top of the screen, it is allowed if it's done programmatically,
525 // when the menu is hidden. This allows the editable area to cover the
526 // full screen height.
527 //
528 // Test cases
529 // ----------
530 //
531 // Use the following extra files:
532 //
533 // init.el:
534 // ;; Hide menu and place frame slightly above the top of the screen.
535 // (setq ns-auto-hide-menu-bar t)
536 // (set-frame-position (selected-frame) 0 -20)
537 //
538 // Test 1:
539 //
540 // emacs -Q -l init.el
541 //
542 // Result: No menu bar, and the title bar should be above the screen.
543 //
544 // Test 2:
545 //
546 // emacs -Q
547 //
548 // Result: Menu bar visible, frame placed immediately below the menu.
