501 // possible to hide it when the application is active. To ensure that
502 // this work properly, the menu bar and window constraining are
503 // deferred until the application becomes active.
504 //
505 // Even though it's not possible to manually move a window above the
506 // top of the screen, it is allowed if it's done programmatically,
507 // when the menu is hidden. This allows the editable area to cover the
508 // full screen height.
509 //
510 // Test cases
511 // ----------

515 // init.el:
516 // ;; Hide menu and place frame slightly above the top of the screen.
517 // (setq ns-auto-hide-menu-bar t)
518 // (set-frame-position (selected-frame) 0 -20)
519 //
520 // Test 1:

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