480// It's possible to hide the menu bar. However, technically, it's only
481// possible to hide it when the application is active. To ensure that
482// this work properly, the menu bar and window constraining are
483// deferred until the application becomes active.
484//
485// Even though it's not possible to manually move a window above the
486// top of the screen, it is allowed if it's done programmatically,
487// when the menu is hidden. This allows the editable area to cover the
488// full screen height.
489//
490// Test cases
491// ----------
492//
493// Use the following extra files:
494//
495// init.el:
496// ;; Hide menu and place frame slightly above the top of the screen.
497// (setq ns-auto-hide-menu-bar t)
498// (set-frame-position (selected-frame) 0 -20)
499//
500// Test 1:
501//
502// emacs -Q -l init.el
503//
504// Result: No menu bar, and the title bar should be above the screen.
505//
506// Test 2:
507//
508// emacs -Q
509//
510// Result: Menu bar visible, frame placed immediately below the menu.
