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

515 // ;; Hide menu and place frame slightly above the top of the screen.
516 // (setq ns-auto-hide-menu-bar t)
517 // (set-frame-position (selected-frame) 0 -20)
518 //

521 // emacs -Q -l init.el
522 //
523 // Result: No menu bar, and the title bar should be above the screen.
