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

2089 This can happen like so:
|
|
|
2090
|

|
2091 - We are waiting in XtAppNextEvent()
|
|
|
2092 - Process generates output
|

2093 - Process is marked as being ready
|
|
|
2094 - Process dies, SIGCHLD gets generated before we return (!?)
|
|
|
2095 It could happen I guess.
|
|
|
2096 - sigchld_handler() marks process as dead
|
|
|
2097 - Somehow we end up getting a new KeyPress event on the queue
|
|
|
2098 at the same time (I'm really so sure how that happens but I'm
|
|
|
2099 not sure it can't either so let's assume it can...).
|
|
|
2100 - Key events have priority so we return that instead of the proc.
|
|
|
2101 - Before dispatching the lisp key event we call status_notify()
|
|
|
2102 - Which deselects the process that SIGCHLD marked as dead.
|
|
|
2103
|
|
|
2104 Thus we never remove it from _with_input and turn it into a lisp
|
|
|
2105 event, so we need to do it here. But this does not mean that we're
|
|
|
2106 throwing away the last block of output - status_notify() has already
|
|
|
2107 taken care of running the proc filter or whatever.
