Keyboard events from external client window do not reach xemacs
(XtAppProcessEvent inside xemacs does not return). Mouse events are
OK (XtAppProcessEvent returns and all keyboard input handled
properly). When I use Xt external client, keyboard events are always
lost. When I use Xm external client, initially this also happens, but
after some mouse actions in client window it inpredictably becomes OK.
Client program is always the same, it is just linked with different
libextcli.

New subject: external widget in 21.2.38
External widget behavior is a bit better. Xm external client works
entirely OK: just after calling (make-frame) external widget window
begins responding to all mouse and keyboard events. Xt external
client behaves the same way: mouse events from it reach xemacs, but
keyboard events do not.
Removing regular X frame by just closing its top-level window using
window manager works normally. However, with external frame this is
not the same. After doing so xemacs hangs like this:
#0 0x821441f in _r_select ()
#1 0x80316a2b in _XWaitForReadable () from /usr/lib/libX11.so

One can force _XReply () and XSync () to return by debugger and
continue. Doing so causes XmuPrintDefaultErrorMessage to emit several
`unexpected async reply' messages. Then xemacs hangs a bit later in a
similar way:
#0 0x821441f in _r_select ()
#1 0x80316a2b in _XWaitForReadable () from /usr/lib/libX11.so
#2 0x80316f0e in _XRead () from /usr/lib/libX11.so

#4 0x8031456a in XSync () from /usr/lib/libX11.so
#5 0x81c7180 in x_error_occurred_p ()
at xemacs-21.2/src/device-x.c:1078
After forcing XSync () to return again it continues without visible
flaws.

What set of X events is expected to reach MaskableEventHandler in
client and get re- sent to xemacs? This is not the case for KeyPress
events. In Motif external client they do not reach external client
app if mouse pointer is in window of EmacsFrame widget. Otherwise
they get into window of EmacsShell widget (shared with external client
widget) and get re- sent. In Xt external client they never reach
external client app and xemacs never receives them.

I don't think anybody knows. As far as the release plans are
concerned, that code is undocumented bitrot. Ben Wing wrote it; I'll
ask him when I talk to him next. You can email him <ben(a)666.com> but
he's way backlogged. Jamie Zawinski's page (IIRC
http://www.jwz.org/doc/xemacs-wish-list.html, or maybe s/doc/docs/)
has some suggestions for improving the external widget code. I plan
to add this to the "for future development" docs in the release pages
but it's low priority.
If you find out anything, let us know.

has some suggestions for improving the external widget code.
The correct URL is <http://www.jwz.org/doc/xemacs-wishlist.html>;. It
assumes that at time of writing (in v. 19.14 or 20.2) it worked
reliably, which was not the case. The `bitrot' has just occured at
least in '96.

Hey, I never saw this and (8) is remarkably similar to the gutters.
