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