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'.
looking-at call doesn't clobber its value when we want to use it to back up
before the error we discard.
Make sure compilation-error-list is at least two elts long before checking
its first two elts for being in the same file.
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.
