749 This can happen like so:
|
|
|
750

751 - We are waiting in XtAppNextEvent()
|
|
|
752 - Process generates output
|
|
|
753 - Process is marked as being ready
|
|
|
754 - Process dies, SIGCHLD gets generated before we return (!?)
|
|
|
755 It could happen I guess.
|
|
|
756 - sigchld_handler() marks process as dead
|
|
|
757 - Somehow we end up getting a new KeyPress event on the queue
|
|
|
758 at the same time (I'm really so sure how that happens but I'm
|
|
|
759 not sure it can't either so let's assume it can...).
|
|
|
760 - Key events have priority so we return that instead of the proc.
|
|
|
761 - Before dispatching the lisp key event we call status_notify()
|
|
|
762 - Which deselects the process that SIGCHLD marked as dead.
|
|
|
763
|
|
|
764 Thus we never remove it from _with_input and turn it into a lisp
|
|
|
765 event, so we need to do it here. But this does not mean that we're
|
|
|
766 throwing away the last block of output - status_notify() has already
|
|
|
767 taken care of running the proc filter or whatever.

1678 /* X bogusly doesn't define the interpretations of any bits besides
|
|
|
1679 ModControl, ModShift, and ModLock; so the Interclient Communication
|
|
|
1680 Conventions Manual says that we have to bend over backwards to figure
|
|
|
1681 out what the other modifier bits mean. According to ICCCM:
|
|
|
1682
|
|
|
1683 - Any keycode which is assigned ModControl is a "control" key.
|
|
|
1684
|
|
|
1685 - Any modifier bit which is assigned to a keycode which generates Meta_L
|
|
|
1686 or Meta_R is the modifier bit meaning "meta". Likewise for Super, Hyper,
|
|
|
1687 etc.
|
|
|
1688
|
|
|
1689 - Any keypress event which contains ModControl in its state should be
|
|
|
1690 interpreted as a "control" character.
|
|
|
1691
|
|
|
1692 - Any keypress event which contains a modifier bit in its state which is
|
|
|
1693 generated by a keycode whose corresponding keysym is Meta_L or Meta_R
|
|
|
1694 should be interpreted as a "meta" character. Likewise for Super, Hyper,
|
|
|
1695 etc.
|
|
|
1696
|
|
|
1697 - It is illegal for a keysym to be associated with more than one modifier
|
|
|
1698 bit.
|
|
|
1699
|
|
|
1700 This means that the only thing that emacs can reasonably interpret as a
|
|
|
1701 "meta" key is a key whose keysym is Meta_L or Meta_R, and which generates
|
|
|
1702 one of the modifier bits Mod1-Mod5.
|
|
|
1703
|
|
|
1704 Unfortunately, many keyboards don't have Meta keys in their default
|
|
|
1705 configuration. So, if there are no Meta keys, but there are "Alt" keys,
|
|
|
1706 emacs will interpret Alt as Meta. If there are both Meta and Alt keys,
|
|
|
1707 then the Meta keys mean "Meta", and the Alt keys mean "Alt" (it used to
|
|
|
1708 mean "Symbol," but that just confused the hell out of way too many people).
|
|
|
1709
|
|
|
1710 This works with the default configurations of the 19 keyboard-types I've
|
|
|
1711 checked.
|
|
|
1712
|
|
|
1713 Emacs detects keyboard configurations which violate the above rules, and
|
|
|
1714 prints an error message on the standard-error-output. (Perhaps it should
|
|
|
1715 use a pop-up-window instead.)
