578// Window constraining
579// -------------------
580//
581// To ensure that the windows are not placed under the menu bar, they
582// are typically moved by the call-back constrainFrameRect. However,
583// by overriding it, it's possible to inhibit this, leaving the window
584// in it's original position.
585//
586// It's possible to hide the menu bar. However, technically, it's only
587// possible to hide it when the application is active. To ensure that
588// this work properly, the menu bar and window constraining are
589// deferred until the application becomes active.
590//
591// Even though it's not possible to manually move a window above the
592// top of the screen, it is allowed if it's done programmatically,
593// when the menu is hidden. This allows the editable area to cover the
594// full screen height.
595//
596// Test cases
597// ----------
598//
599// Use the following extra files:
600//
601// init.el:
602// ;; Hide menu and place frame slightly above the top of the screen.
603// (setq ns-auto-hide-menu-bar t)
604// (set-frame-position (selected-frame) 0 -20)
605//
606// Test 1:
607//
608// emacs -Q -l init.el
609//
610// Result: No menu bar, and the title bar should be above the screen.
611//
612// Test 2:
613//
614// emacs -Q
615//
616// Result: Menu bar visible, frame placed immediately below the menu.
