are not 5 elements long.
(EVENT_HEAD): Work correctly on all sorts of events, not just
events with parameters.
(EVENT_WINDOW, EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON,
EVENT_WINDOW_POSN, EVENT_TIMESTAMP): These aren't useful
anymore; this information may appear twice in an event. These
are replaced by the POSN_ accessors, which are meant to be
composed with the EVENT_START and EVENT_END accessors.
(EVENT_START, EVENT_END): Two new accessors, to get at the
starting and ending position of an event.
(POSN_WINDOW, POSN_BUFFER_POSN, PONS_SCROLLBAR_BUTTON,
POSN_WINDOW_POSN, POSN_TIMESTAMP): New macros, to futher
diasassemble the values returned by EVENT_START and EVENT_END.
* keyboard.h (Qevent_unmodified): Extern declaration replaced by...
(Qevent_symbol_elements): This.
(EVENT_HEAD_UNMODIFIED): Use the Qevent_symbol_elements
property, rather than the Qevent_unmodified property.
testing for EVENT_HAS_PARAMETERS; EVENT_HEAD works properly on
all sorts of events now.
(read_key_sequence): Use the new accessors to decide in which window
an event occurred.
* keyboard.c (Qevent_unmodified): Replaced by...
(Qevent_symbol_elements): New property.
(syms_of_keyboard): initialize and staticpro the latter, not the
former.
* keyboard.c (readable_events): This doesn't need to scan and
discard mouse release events anymore; it just uses
EVENT_QUEUES_EMPTY.
(kbd_buffer_get_event): No need to skip past mouse release events.
* keyboard.c (button_down_location): New variable, which
stores the location at which each button was pressed, so we
can build a complete drag event when the button is released.
(make_lispy_event): When a button is pressed, record its
location in button_down_location, and turn it into a `down'
event. When a button is released, compare its release
location with its press location, and decide whether to call
it a `click' or `drag' event.
Change mouse movement events to be arranged like click events.
(format_modifiers): Note that the click modifier has no
written representation.
(modifier_names, modifer_symbols): New variables, used to
create the Qevent_symbol_elements property.
(modify_event_symbol): Change the format of the modified
symbol cache; there are too many modifier bits now to use a
vector indexed by a modifier mask. Use an assoc-list instead.
Document the format of the cache.
Put the Qevent_symbol_elements property on each new symbol,
instead of a Qevent_unmodified property.
(symbols_of_keyboard): Put Qevent_symbol_elements properties on
the symbols specified in head_table, not Qevent_unmodifed properties.
Initialize and staticpro modifier_symbols, and staticpro the
window elements of button_down_location.
(init_intervals, make_interval,
mark_interval, mark_interval_tree): New functions conditionally
defined.
(make_uninit_string): Call INITIALIZE_INTERVAL.
(INIT_INTERVALS, UNMARK_BALANCE_INTERVALS, MARK_INTERVAL_TREE):
New macros, conditionally defined.
(mark_object): Call MARK_INTERVAL_TREE in case Lisp_String.
(gc_sweep): If text properties are in use, place all unmarked
intervals on the free list. Call UNMARK_BALANCE_INTERVALS on
`buffer->intervals' when unmarking `buffer'.
(compact_strings): Include INTERVAL_PTR_SIZE in calculation for
target of bcopy when relocating strings.
(init_alloc_once): Call INIT_INTERVALS.
(make_pure_string): Include INTERVAL_PTR_SIZE in calculation of
`size'.
and TEMP_SET_PT are function calls.
Similarly for BUF_SET_PT and BUF_TEMP_SET_PT.
Added DECLARE_INTERVALS to buffer structure to conditionally
compile an interval tree into it..
just because we restored its configuration.
* window.c (Fset_window_configuration): Don't forget to set the
frame's selected window when we can't call Fselect_window.
modifier bits denote meta keys.
(x_find_modifier_meanings): New function, to set x_meta_mod_mask.
(x_convert_modifiers): Use that.
(x_term_init): Call x_find_modifier_meanings.
* xterm.c (XTread_socket): Pass PropertyNotify events from the
root window to x_invalidate_cut_buffer_cache.
(x_term_init): Call x_watch_cut_buffer_cache here.
interface to the cut buffer now.
(NUM_CUT_BUFFERS, cut_buffer_atom, cut_buffer_value,
cut_buffer_cached, cut_buffer_just_set): New variables.
(Fx_own_selection, Fx_selection_value): Dike out the code to
handle CUT_BUFFER0 requests.
(Fx_get_cut_buffer, Fx_set_cut_buffer, x_watch_cut_buffer_cache,
x_invalidate_cut_buffer_cache): New functions.
(syms_of_xselect): Don't bother to initialize Qcut_buffer0.
Initialize and staticpro cut_buffer_value, and defsubr
Sx_get_cut_buffer and Sx_set_cut_buffer.
* xterm.c (XTread_socket): Pass PropertyNotify events from the
root window to x_invalidate_cut_buffer_cache.
(x_term_init): Call x_watch_cut_buffer_cache here.
pain in the neck to staticpro, into a vector, which is easier.
(read_char, Frecent_keys): Access recent_keys as a lisp vector,
not a C array.
(init_keyboard): Set recent_keys to be a vector, and staticpro
it.
buried only if the BUFFER argument was nil. Instead, undisplay the
buffer whenever it's displayed in the selected window, no matter
how it was specified by BUFFER. This is how it behaves in 18.58,
and I can't find any ChangeLog entry in 18.58 or 19.0 saying why
they differ. Fix the doc string accordingly.
handle memory exhaustion, it's better to return an error code to
them than to call abort.
(obtain): If we cannot allocate more memory, don't call
abort. Instead, return non-zero iff the allocation is successful.
(get_more_space): If obtain fails, return zero.
(get_bloc): Return zero if we can't allocate the new bloc.
(r_alloc_sbrk): Return zero if we can't allocate more memory.
(r_alloc): If we can't allocate more memory, set *PTR to zero and
return zero.
(r_re_alloc): If we can't allocate more memory, leave *PTR
unchanged, and return zero.
* ralloc.c (warnfunction): Renamed to warn_function; users changed.
macro, set Vlast_event_frame to Qmacro, instead of leaving it set
to the frame of the previous real event.
(read_key_sequence): If Vlast_event_frame isn't a frame, don't
bother switching buffers.
(syms_of_keyboard): Doc fix for Vlast_event_frame.
(Vlast_event_frame): Doc fix.
* keyboard.c (format_modifiers, reorder_modifiers): Handle the new
modifier bits.
down_modifier, drag_modifier): New modifiers, to support the new
input system. Re-arranged modifiers so that their bits are in
canonical order; this makes reorder_modifiers slightly simpler.
its `height' field; we may need to know the window's old buffer
once we have restored it from a window configuration.
Fset_window_configuration): When we restore a window, if its
`height' field is a buffer, restore its `buffer' field from that.
This allows us to leave the window's buffer unchanged if the
buffer recorded in the configuration is dead.
* window.c (delete_all_subwindows): Removed unused variable named
"count".
Qt.
* keymap.c (Fwhere_is_internal): Don't forget to advance map to
the next element when we find something that is neither a vector
nor a cons. Don't forget to QUIT in the appropriate places,
either.
