|

743

744 - We are waiting in XtAppNextEvent()
|

|
745 - Process generates output
|

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

|
|
|
1827 ModControl, ModShift, and ModLock; so the Interclient Communication
|
|
|
1828 Conventions Manual says that we have to bend over backwards to figure
|
|
|
1829 out what the other modifier bits mean. According to ICCCM:
|
|
|
1830
|
|
|
1831 - Any keycode which is assigned ModControl is a "control" key.
|
|
|
1832
|
|
|
1833 - Any modifier bit which is assigned to a keycode which generates Meta_L
|
|
|
1834 or Meta_R is the modifier bit meaning "meta". Likewise for Super, Hyper,
|
|
|
1835 etc.
|
|
|
1836
|
|
|
1837 - Any keypress event which contains ModControl in its state should be
|
|
|
1838 interpreted as a "control" character.
|
|
|
1839
|
|
|
1840 - Any keypress event which contains a modifier bit in its state which is
|
|
|
1841 generated by a keycode whose corresponding keysym is Meta_L or Meta_R
|
|
|
1842 should be interpreted as a "meta" character. Likewise for Super, Hyper,
|
|
|
1843 etc.
|
|
|
1844
|
|
|
1845 - It is illegal for a keysym to be associated with more than one modifier
|
|
|
1846 bit.
|
|
|
1847
|
|
|
1848 This means that the only thing that emacs can reasonably interpret as a
|
|
|
1849 "meta" key is a key whose keysym is Meta_L or Meta_R, and which generates
|
|
|
1850 one of the modifier bits Mod1-Mod5.
|
|
|
1851
|
|
|
1852 Unfortunately, many keyboards don't have Meta keys in their default
|
|
|
1853 configuration. So, if there are no Meta keys, but there are "Alt" keys,
|
|
|
1854 emacs will interpret Alt as Meta. If there are both Meta and Alt keys,
|
|
|
1855 then the Meta keys mean "Meta", and the Alt keys mean "Alt" (it used to
|
|
|
1856 mean "Symbol," but that just confused the hell out of way too many people).
|
|
|
1857
|
|
|
1858 This works with the default configurations of the 19 keyboard-types I've
|
|
|
1859 checked.
|
|
|
1860
|
|
|
1861 Emacs detects keyboard configurations which violate the above rules, and
|
|
|
1862 prints an error message on the standard-error-output. (Perhaps it should
|
|
|
1863 use a pop-up-window instead.)
