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

1872 effect of widgets only getting updated when XEmacs only goes into
|
|
|
1873 idle, or some other event causes processing of the X event queue.
|
|

1874
|

1875 XtAppProcessEvent can get called from the following places:

1878 any non-X event will take precedence and this means that we
|
|
|
1879 cannot rely on it to do the right thing at the right time for
|
|
|
1880 widget display.
|
|
|
1881
|
|
1204
|
1882 emacs_Xt_drain_queue () - this happens when SIGIO gets tripped,
|
|
|
1883 processing the event queue allows C-g to be checked for. It gets
|
|
|
1884 called from emacs_Xt_event_pending_p (). #### Update this comment.
|
|

|
1885
|
|
|
1886 In order to solve this I have tried introducing a list primitive -
|
|
|
1887 dispatch-non-command-events - which forces processing of X events
|
|
|
1888 related to display. Unfortunately this has a number of problems,
|
|
|
1889 one is that it is possible for event_stream_event_pending_p to
|
|
|
1890 block for ever if there isn't actually an event. I guess this can
|
|
|
1891 happen if we drop the synthetic event for reason. It also relies on
|
|
|
1892 SIGIO processing which makes things rather fragile.
|
|
|
1893
|
|
|
1894 People have seen behaviour whereby XEmacs blocks until you move the
|
|
|
1895 mouse. This seems to indicate that dispatch-non-command-events is
|
|
|
1896 blocking. It may be that in a SIGIO world forcing SIGIO processing
|
|
|
1897 does the wrong thing.

2329 This can happen like so:
|
|

2330

2331 - We are waiting in XtAppNextEvent()
|
|
|
2332 - Process generates output

2333 - Process is marked as being ready
|
|
|
2334 - Process dies, SIGCHLD gets generated before we return (!?)
|
|
|
2335 It could happen I guess.
|
|
|
2336 - sigchld_handler() marks process as dead
|
|
|
2337 - Somehow we end up getting a new KeyPress event on the queue
|
|
|
2338 at the same time (I'm really so sure how that happens but I'm
|
|
|
2339 not sure it can't either so let's assume it can...).
|
|
|
2340 - Key events have priority so we return that instead of the proc.
|
|
|
2341 - Before dispatching the lisp key event we call status_notify()
|
|
|
2342 - Which deselects the process that SIGCHLD marked as dead.
|
|
|
2343
|
|
|
2344 Thus we never remove it from _with_input and turn it into a lisp
|
|
|
2345 event, so we need to do it here. But this does not mean that we're
|
|
|
2346 throwing away the last block of output - status_notify() has already
|
|
|
2347 taken care of running the proc filter or whatever.
