271 ModControl, ModShift, and ModLock; so the Interclient Communication
|
|
|
272 Conventions Manual says that we have to bend over backwards to figure
|
|
|
273 out what the other modifier bits mean. According to ICCCM:
|
|
|
274
|
|
|
275 - Any keycode which is assigned ModControl is a "control" key.
|
|
|
276
|
|
|
277 - Any modifier bit which is assigned to a keycode which generates Meta_L
|
|
|
278 or Meta_R is the modifier bit meaning "meta". Likewise for Super, Hyper,
|
|
|
279 etc.
|
|
|
280
|
|
|
281 - Any keypress event which contains ModControl in its state should be
|
|
|
282 interpreted as a "control" character.
|
|
|
283
|
|
|
284 - Any keypress event which contains a modifier bit in its state which is
|
|
|
285 generated by a keycode whose corresponding keysym is Meta_L or Meta_R
|
|
|
286 should be interpreted as a "meta" character. Likewise for Super, Hyper,
|
|
|
287 etc.
|
|
|
288
|
|
|
289 - It is illegal for a keysym to be associated with more than one modifier
|
|
|
290 bit.
|
|
|
291
|
|
|
292 This means that the only thing that emacs can reasonably interpret as a
|
|
|
293 "meta" key is a key whose keysym is Meta_L or Meta_R, and which generates
|
|
|
294 one of the modifier bits Mod1-Mod5.
|
|
|
295
|
|
|
296 Unfortunately, many keyboards don't have Meta keys in their default
|
|
|
297 configuration. So, if there are no Meta keys, but there are "Alt" keys,
|
|
|
298 emacs will interpret Alt as Meta. If there are both Meta and Alt keys,
|
|
|
299 then the Meta keys mean "Meta", and the Alt keys mean "Alt" (it used to
|
|
|
300 mean "Symbol," but that just confused the hell out of way too many people).
|
|
|
301
|
|
|
302 This works with the default configurations of the 19 keyboard-types I've
|
|
|
303 checked.
|
|
|
304
|
|
|
305 Emacs detects keyboard configurations which violate the above rules, and
|
|
|
306 gives a warning. */

|
|
|
1823 Here is the problem:
|
|
|
1824
|
|
|
1825 When widgets get mapped / changed etc the actual display updates
|
|
|
1826 are done asynchronously via X events being processed - this
|
|
|
1827 normally happens when XtAppProcessEvent() gets called. However, if
|
|
|
1828 we are executing lisp code or even doing redisplay we won't
|
|
|
1829 necessarily process X events for a very long time. This has the
|
|
|
1830 effect of widgets only getting updated when XEmacs only goes into
|
|
|
1831 idle, or some other event causes processing of the X event queue.
|
|
|
1832
|
|
|
1833 XtAppProcessEvent can get called from the following places:
|
|
|
1834
|
|
|
1835 emacs_Xt_next_event () - this is normal event processing, almost
|
|
|
1836 any non-X event will take precedence and this means that we
|
|
|
1837 cannot rely on it to do the right thing at the right time for
|
|
|
1838 widget display.
|
|
|
1839
|
|
1204
|
1840 emacs_Xt_drain_queue () - this happens when SIGIO gets tripped,
|
|
|
1841 processing the event queue allows C-g to be checked for. It gets
|
|
|
1842 called from emacs_Xt_event_pending_p (). #### Update this comment.
|
|
448
|
1843
|
|
|
1844 In order to solve this I have tried introducing a list primitive -
|
|
|
1845 dispatch-non-command-events - which forces processing of X events
|
|
|
1846 related to display. Unfortunately this has a number of problems,
|
|
|
1847 one is that it is possible for event_stream_event_pending_p to
|
|
|
1848 block for ever if there isn't actually an event. I guess this can
|
|
|
1849 happen if we drop the synthetic event for reason. It also relies on
|
|
|
1850 SIGIO processing which makes things rather fragile.
|
|
|
1851
|
|
|
1852 People have seen behaviour whereby XEmacs blocks until you move the
|
|
|
1853 mouse. This seems to indicate that dispatch-non-command-events is
|
|
|
1854 blocking. It may be that in a SIGIO world forcing SIGIO processing
|
|
|
1855 does the wrong thing.

|

2287 This can happen like so:
|
|
|
2288
|
|
|
2289 - We are waiting in XtAppNextEvent()
|
|
|
2290 - Process generates output
|
|
|
2291 - Process is marked as being ready
|
|
|
2292 - Process dies, SIGCHLD gets generated before we return (!?)
|
|
|
2293 It could happen I guess.
|
|
|
2294 - sigchld_handler() marks process as dead
|
|
|
2295 - Somehow we end up getting a new KeyPress event on the queue
|
|
|
2296 at the same time (I'm really so sure how that happens but I'm
|
|
|
2297 not sure it can't either so let's assume it can...).
|
|
|
2298 - Key events have priority so we return that instead of the proc.
|
|
|
2299 - Before dispatching the lisp key event we call status_notify()
|
|
|
2300 - Which deselects the process that SIGCHLD marked as dead.
|
|
|
2301
|
|
|
2302 Thus we never remove it from _with_input and turn it into a lisp
|
|
|
2303 event, so we need to do it here. But this does not mean that we're
|
|
|
2304 throwing away the last block of output - status_notify() has already
|
|
|
2305 taken care of running the proc filter or whatever.

3206 We use this to make possible the usage of standard key bindings on keyboards
|
|
|
3207 where the keys that those bindings assume are not available; for example, on
|
|
|
3208 a Russian keyboard, one can type C-Cyrillic_che C-Cyrillic_a and have XEmacs
|
|
|
3209 use the binding for C-x C-f, rather than give an error message that
|
|
|
3210 C-Cyrillic_che C-Cyrillic_a is not bound.

3212 Entries are either nil, which means the corresponding key code does not map
|
|

3213 to a non-function key in the US layout, a single character, meaning it maps to
|
|
|
3214 that character, or a vector of two characters, the first indicating the
|
|
|
3215 unshifted mapping, the second the shifted mapping for the US layout.
