return value of XWithdrawWindow; it could indicate that the window
wasn't successfully redrawn.
* xterm.c (x_make_frame_invisible): Use XWithdrawWindow when
available [HAVE_X11R4]; send the UnmapNotify event when
appropriate [HAVE_X11]; just unmap the window if that's all that's
needed [not HAVE_X11].
* xterm.c (x_set_text_property): Removed; it's only called from
one place. Who wants *another* layer of indirection?
* xterm.c: Use the FRAME_X_WINDOW macro, for readability.
* xterm.c (x_death_handler): Renamed to x_connection_closed.
(x_term_init): Use x_connection_closed as the SIGPIPE handler.
* xterm.c (acceptable_x_error_p, x_handler_error_gracefully,
x_error_handler): Removed; you can't catch X errors this way,
since you can't perform X operations from within an X error
handler, and even though we call error, we're still within an X
error handler.
(x_error_quitter, x_error_catcher): New functions, for panicking
on and catching X protocol errors.
(x_caught_error_message): Buffer for caught X errors.
(x_catch_errors, x_check_errors, x_uncatch_errors): New functions
for catching errors.
(x_term_init): Set the error handler to x_error_quitter, rather
than x_error_handler.
* xterm.c (x_death_handler): Renamed to x_connection_closed.
(x_term_init): Use x_connection_closed as the SIGPIPE handler.
* xterm.c (acceptable_x_error_p, x_handler_error_gracefully,
x_error_handler): Removed; you can't catch X errors this way,
since you can't perform X operations from within an X error
handler, and even though we call error, we're still within an X
error handler.
(x_error_quitter, x_error_catcher): New functions, for panicking
on and catching X protocol errors.
(x_caught_error_message): Buffer for caught X errors.
(x_catch_errors, x_check_errors, x_uncatch_errors): New functions
for catching errors.
(x_term_init): Set the error handler to x_error_quitter, rather
than x_error_handler.
hasn't specified the icon position. Let the window manager put
the icon where it likes.
* xfns.c (x_set_name): Use XSetWM{Name,IconName} when available
[HAVE_X11R4], or XSetIconName and XStoreName otherwise.
* xfns.c: Use the FRAME_X_WINDOW for readability.
* xfns.c (x_set_mouse_color): Use x_catch_errors, x_check_errors,
and x_uncatch errors to avoid crashing if the user selects an
odd cursor.
* xfns.c (select_visual): Use XVisualIDFromVisual when available
[HAVE_X11R4].
one-line windows are the minibuffer, or that all minibuffers are
one line high. Use MINI_WINDOW_P.
* window.c (change_window_height): If the size of the window will
shrink below the minimum, this code would only try to delete it if
it had a parent. Well, even if the window doesn't have a parent,
you want Fdelete_window to signal an error, since you're trying to
resize one of the undeleteable windows into nothingness. So call
Fdelete_window even if the window doesn't have a parent.
* window.c (MINSIZE): Add kludge so that the minibuffer is always
allowed to shrink to one line in height.
(MINSIZE, CURBEG, CURSIZE): Change these so that their argument
are always Lisp_Objects, not struct window *'s.
(change_window_height): Changed accordingly.
test TERMIOS before TERMIO; when two options might both be
defined, test the most recent first, so that the most recent
functions get used.
* sysdep.c [HAVE_TERMIO] (init_baud_rate): Don't use tcgetattr
unless HAVE_TCATTR is defined. Only very rarely do termio systems
have the tc{get,set}attr macros.
* sysdep.c: #include "systty.h", not "systerm.h".
* dispnew.c (update_frame): Change the way we handle
cursor_in_echo_area. Firstly, ignore this if the frame we're
updating doesn't have a minibuffer. Secondly, don't handle the
selected frame specially. Thirdly, don't assume that the
minibuffer is only one line high. If cursor_in_echo_area < 0, put
the cursor in the upper-left corner; if cursor_in_echo_area > 0,
put it on the lowest non-empty line in the minibuffer window, or
on the top line.
* dispnew.c (direct_output_for_insert): Fail if
cursor_in_echo_area is set; we don't want to do the typing there.
(direct_output_for_insert): Same.
