137 /* X bogusly doesn't define the interpretations of any bits besides
|
|
|
138 ModControl, ModShift, and ModLock; so the Interclient Communication
|
|
|
139 Conventions Manual says that we have to bend over backwards to figure
|
|
|
140 out what the other modifier bits mean. According to ICCCM:
|
|
|
141
|
|
|
142 - Any keycode which is assigned ModControl is a "control" key.
|
|
|
143
|
|
|
144 - Any modifier bit which is assigned to a keycode which generates Meta_L
|
|
|
145 or Meta_R is the modifier bit meaning "meta". Likewise for Super, Hyper,
|
|
|
146 etc.
|
|
|
147
|
|
|
148 - Any keypress event which contains ModControl in its state should be
|
|
|
149 interpreted as a "control" character.
|
|
|
150
|
|
|
151 - Any keypress event which contains a modifier bit in its state which is
|
|
|
152 generated by a keycode whose corresponding keysym is Meta_L or Meta_R
|
|
|
153 should be interpreted as a "meta" character. Likewise for Super, Hyper,
|
|
|
154 etc.
|
|
|
155
|
|
|
156 - It is illegal for a keysym to be associated with more than one modifier
|
|
|
157 bit.
|
|
|
158
|
|
|
159 This means that the only thing that emacs can reasonably interpret as a
|
|
|
160 "meta" key is a key whose keysym is Meta_L or Meta_R, and which generates
|
|
|
161 one of the modifier bits Mod1-Mod5.
|
|
|
162
|
|
|
163 Unfortunately, many keyboards don't have Meta keys in their default
|
|
|
164 configuration. So, if there are no Meta keys, but there are "Alt" keys,
|
|
|
165 emacs will interpret Alt as Meta. If there are both Meta and Alt keys,
|
|
|
166 then the Meta keys mean "Meta", and the Alt keys mean "Alt" (it used to
|
|
|
167 mean "Symbol," but that just confused the hell out of way too many people).
|
|
|
168
|
|
|
169 This works with the default configurations of the 19 keyboard-types I've
|
|
|
170 checked.
|
|
|
171
|
|
|
172 Emacs detects keyboard configurations which violate the above rules, and
|
|
|
173 prints an error message on the standard-error-output. (Perhaps it should
|
|
|
174 use a pop-up-window instead.)

|
|
|
1813 - Process dies, SIGCHLD gets generated before we return (!?)
|
|
|
1814 It could happen I guess.
|
|
|
1815 - sigchld_handler() marks process as dead
|
|
|
1816 - Somehow we end up getting a new KeyPress event on the queue
|
|
|
1817 at the same time (I'm really so sure how that happens but I'm
|
|
|
1818 not sure it can't either so let's assume it can...).
|
|
|
1819 - Key events have priority so we return that instead of the proc.
|
|
|
1820 - Before dispatching the lisp key event we call status_notify()
|
|
|
1821 - Which deselects the process that SIGCHLD marked as dead.
|
|
|
1822
|
|
|
1823 Thus we never remove it from _with_input and turn it into a lisp
|
|
|
1824 event, so we need to do it here. But this does not mean that we're
|
|
|
1825 throwing away the last block of output - status_notify() has already
|
|
|
1826 taken care of running the proc filter or whatever.
