509// Window constraining
510// -------------------
511//
512// To ensure that the windows are not placed under the menu bar, they
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//
545// emacs -Q
546//
547// Result: Menu bar visible, frame placed immediately below the menu.
