24.3.50; x-popup-menu just returns nil |

Hello,
in emacs -Q, I eval the following:
--8<---------------cut here---------------start------------->8---
(defun foo (event)
(interactive "e")
(message "%s" (x-popup-menu event (mouse-menu-bar-map))))
(global-set-key
[(meta control mouse-3)] ;just some free key
#'foo)
--8<---------------cut here---------------end--------------->8---
Now, I hit M-C-mouse-3 somewhere. The menu appears at the right place.
I select any item, and FOO messages "nil" instead of a list of events.
This is the bug.
However, when I redefine FOO so that it uses t instead of EVENT as first
argument of `x-popup-menu', it works as expected!
The problem seems to be system specific. I see it on Debian Linux with
X, Drew Adams doesn't see it under Windows.
I use openbox, but the behavior is the same in an X session without any
window manager.
Regards,
Michael.

I continued debugging xmenu_show and found that after the call to
`create_and_show_popup_menu', `menu_item_selection' is only != 0 in the
good case.
Perhaps Jan could help us out, then. Jan, it sounds like GTK doesn't
like what we do with the menu, for some reason.
The Gtk+ assumtion is that popup is done on key down, not key up, i.e.:
(global-set-key
[(meta control down mouse-3)] ;just some free key
#'foo)
It is very strange to popup a menu on key up. From the Gtk+ point of view,
that corresponds to popping up without a mouse click, hence the error. I have
checked in a fix in trunk.
