Haiku's BMenu is is different from BeOS's in handling Escape and Alt-W/Q.

** Escape

In BeOS, when the menu is sticky and the mouse pointer is not held over it, the escape key closes only the topmost menu window, the last one in the chain. This works the same in application menubars, in Tracker's context menu and in Deskbar. Escape collapses piece by piece.

In Haiku, application menubars and Deskbar's Leaf menu are immediately fully collapsed by the escape key, while Tracker's context menu is unaffected. Both cases unlike BeOS.

** Alt-W/Alt-Q

In a BeOS application, you can not Alt-W a window or Alt-Q the application while the menubar has a menu open. (Not even shortcuts in the currently open menu have any effect!)

In Haiku, Alt-W/Q work even when in a menu, and I'm guessing the other shortcuts do too. (User error! ;) Anyway is the API safe if this is allowed? Why did Be disallow shortcut use while a menu is open?)

Tracker's context menu/Deskbar's Leaf menu:

In BeOS, Alt-W has no effect on these menu hierarchies. In Haiku, Tracker's menu is collapsed, the root menu left intact, with a submenu saying "<empty>". Deskbar's Leaf menu is reduced to a single orphan menu saying "<emtpy>".

First time that Alt-W:ing the menu has crashed on me.

Keyboard navigation in menus is still very WIP, as you'll have noticed :) It needs also some support on the app_server side, since menu windows don't usually get focus, but still needs to receive keyboard events.

[jackburton]

By the way, the fact that the application window gets the shortcuts event depends on the menus not getting the focus.

Both shortcuts (ALT-W and ALT-Q) aren't added to modal windows. So either we add the kMenuWindowFeel to the check in BWindow::IsModal(), or in BWindow::_InitData(), we change fNoQuitShortcut = IsModal(); with

fNoQuitShortcut = IsModal() Feel() == kMenuWindowFeel;

I'd go with the former, but I don't know if there will be any consequence. Opinions ?

[jackburton]

I added the check for kMenuWindowFeel in BWindow::IsModal() in r23343. Please review. I'll close the bug, though, since it's fixed.
