499 // possible to hide it when the application is active. To ensure that
500 // this work properly, the menu bar and window constraining are
501 // deferred until the application becomes active.
502 //
503 // Even though it's not possible to manually move a window above the
504 // top of the screen, it is allowed if it's done programmatically,
505 // when the menu is hidden. This allows the editable area to cover the
506 // full screen height.
507 //
508 // Test cases
509 // ----------

512 //
513 // init.el:
514 // ;; Hide menu and place frame slightly above the top of the screen.
515 // (setq ns-auto-hide-menu-bar t)
516 // (set-frame-position (selected-frame) 0 -20)
517 //
518 // Test 1:
519 //
520 // emacs -Q -l init.el
521 //
522 // Result: No menu bar, and the title bar should be above the screen.
