556// Window constraining
557// -------------------
558//
559// To ensure that the windows are not placed under the menu bar, they
560// are typically moved by the call-back constrainFrameRect. However,
561// by overriding it, it's possible to inhibit this, leaving the window
562// in it's original position.
563//
564// It's possible to hide the menu bar. However, technically, it's only
565// possible to hide it when the application is active. To ensure that
566// this work properly, the menu bar and window constraining are
567// deferred until the application becomes active.
568//
569// Even though it's not possible to manually move a window above the
570// top of the screen, it is allowed if it's done programmatically,
571// when the menu is hidden. This allows the editable area to cover the
572// full screen height.
573//
574// Test cases
575// ----------
576//
577// Use the following extra files:
578//
579// init.el:
580// ;; Hide menu and place frame slightly above the top of the screen.
581// (setq ns-auto-hide-menu-bar t)
582// (set-frame-position (selected-frame) 0 -20)
583//
584// Test 1:
585//
586// emacs -Q -l init.el
587//
588// Result: No menu bar, and the title bar should be above the screen.
589//
590// Test 2:
591//
592// emacs -Q
593//
594// Result: Menu bar visible, frame placed immediately below the menu.
