|
|
|
125 ModControl, ModShift, and ModLock; so the Interclient Communication
|
|
|
126 Conventions Manual says that we have to bend over backwards to figure
|
|
|
127 out what the other modifier bits mean. According to ICCCM:
|
|
|
128
|
|
|
129 - Any keycode which is assigned ModControl is a "control" key.
|
|
|
130
|
|
|
131 - Any modifier bit which is assigned to a keycode which generates Meta_L
|
|
|
132 or Meta_R is the modifier bit meaning "meta". Likewise for Super, Hyper,
|
|
|
133 etc.
|
|
|
134
|
|
|
135 - Any keypress event which contains ModControl in its state should be
|
|
|
136 interpreted as a "control" character.
|
|
|
137
|
|
|
138 - Any keypress event which contains a modifier bit in its state which is
|
|
|
139 generated by a keycode whose corresponding keysym is Meta_L or Meta_R
|
|
|
140 should be interpreted as a "meta" character. Likewise for Super, Hyper,
|
|
|
141 etc.
|
|
|
142
|
|
|
143 - It is illegal for a keysym to be associated with more than one modifier
|
|
|
144 bit.
|
|
|
145
|
|
|
146 This means that the only thing that emacs can reasonably interpret as a
|
|
|
147 "meta" key is a key whose keysym is Meta_L or Meta_R, and which generates
|
|
|
148 one of the modifier bits Mod1-Mod5.
|
|
|
149
|
|
|
150 Unfortunately, many keyboards don't have Meta keys in their default
|
|
|
151 configuration. So, if there are no Meta keys, but there are "Alt" keys,
|
|
|
152 emacs will interpret Alt as Meta. If there are both Meta and Alt keys,
|
|
|
153 then the Meta keys mean "Meta", and the Alt keys mean "Alt" (it used to
|
|
|
154 mean "Symbol," but that just confused the hell out of way too many people).
|
|
|
155
|
|
|
156 This works with the default configurations of the 19 keyboard-types I've
|
|
|
157 checked.
|
|
|
158
|
|
|
159 Emacs detects keyboard configurations which violate the above rules, and
|
|
|
160 prints an error message on the standard-error-output. (Perhaps it should
|
|
|
161 use a pop-up-window instead.)

|
|
|
1811 Here is the problem:
|
|
|
1812
|
|
|
1813 When widgets get mapped / changed etc the actual display updates
|
|
|
1814 are done asynchronously via X events being processed - this
|
|
|
1815 normally happens when XtAppProcessEvent() gets called. However, if
|
|
|
1816 we are executing lisp code or even doing redisplay we won't
|
|
|
1817 necessarily process X events for a very long time. This has the
|
|
|
1818 effect of widgets only getting updated when XEmacs only goes into
|
|
|
1819 idle, or some other event causes processing of the X event queue.
|
|
|
1820
|
|
|
1821 XtAppProcessEvent can get called from the following places:
|
|
|
1822
|
|
|
1823 emacs_Xt_next_event () - this is normal event processing, almost
|
|
|
1824 any non-X event will take precedence and this means that we
|
|
|
1825 cannot rely on it to do the right thing at the right time for
|
|
|
1826 widget display.
|
|
|
1827
|
|
|
1828 drain_X_queue () - this happens when SIGIO gets tripped,
|
|
|
1829 processing the event queue allows C-g to be checked for. It gets
|
|
|
1830 called from emacs_Xt_event_pending_p ().
|
|
|
1831
|
|
|
1832 In order to solve this I have tried introducing a list primitive -
|
|
|
1833 dispatch-non-command-events - which forces processing of X events
|
|
|
1834 related to display. Unfortunately this has a number of problems,
|
|
|
1835 one is that it is possible for event_stream_event_pending_p to
|
|
|
1836 block for ever if there isn't actually an event. I guess this can
|
|
|
1837 happen if we drop the synthetic event for reason. It also relies on
|
|
|
1838 SIGIO processing which makes things rather fragile.
|
|
|
1839
|
|
|
1840 People have seen behaviour whereby XEmacs blocks until you move the
|
|
|
1841 mouse. This seems to indicate that dispatch-non-command-events is
|
|
|
1842 blocking. It may be that in a SIGIO world forcing SIGIO processing
|
|
|
1843 does the wrong thing.

|

2271 the input from it, probably from status_notify() in the command loop.
|
|
|
2272 This can happen like so:
|
|
|
2273
|
|
|
2274 - We are waiting in XtAppNextEvent()
|
|
|
2275 - Process generates output
|
|
|
2276 - Process is marked as being ready
|
|
|
2277 - Process dies, SIGCHLD gets generated before we return (!?)
|
|
|
2278 It could happen I guess.
|
|
|
2279 - sigchld_handler() marks process as dead
|
|
|
2280 - Somehow we end up getting a new KeyPress event on the queue
|
|
|
2281 at the same time (I'm really so sure how that happens but I'm
|
|
|
2282 not sure it can't either so let's assume it can...).
|
|
|
2283 - Key events have priority so we return that instead of the proc.
|
|
|
2284 - Before dispatching the lisp key event we call status_notify()
|
|
|
2285 - Which deselects the process that SIGCHLD marked as dead.
|
|
|
2286
|
|
|
2287 Thus we never remove it from _with_input and turn it into a lisp
|
|
|
2288 event, so we need to do it here. But this does not mean that we're
|
|
|
2289 throwing away the last block of output - status_notify() has already
|
|
|
2290 taken care of running the proc filter or whatever.
