Initialize margin area images to nil.
(breakpoint-bitmap): New defvar for breakpoint fringe bitmaps.
(breakpoint-enabled-bitmap-face)
(breakpoint-disabled-bitmap-face): New faces for bpt in fringe.
(gdb-info-breakpoints-custom): Use gdb-remove-breakpoint-icons.
(gdb-info-breakpoints-custom): Use gdb-put-breakpoint-icon.
(gdb-mouse-toggle-breakpoint): Handle bpt in fringe.
(gdb-reset): Use gdb-remove-breakpoint-icons.
(gdb-put-string): Add dprop arg to specify alternative display
property (for setting fringe bitmap).
(gdb-remove-strings): Doc fix.
(gdb-put-breakpoint-icon): New defun which displays a breakpoint
icon in fringe (if available), or else as icon or text in display
margin. Creates necessary icons in breakpoint-bitmap,
breakpoint-enabled-icon, and/or breakpoint-disabled-icon. Also
make left window margin if required.
(gdb-remove-breakpoint-icons): New defun to remove breakpoint
icons inserted by gdb-put-breakpoint-icon. Remove left margin if
no longer needed.
(gdb-assembler-custom): Use gdb-remove-breakpoint-icons and
gdb-put-breakpoint-icon.
(gdb-assembler-mode): Don't set left-margin-width here.
numchars arg. Always store event into bufp arg. Return nothing.
Callers changed accordingly.
(glyph_rect): Simplify.
(STORE_KEYSYM_FOR_DEBUG): New macro.
(SET_SAVED_MENU_EVENT): Use inev instead of bufp, etc.
(current_bufp, current_numcharsp) [USE_GTK]: Remove.
(current_hold_quit) [USE_GTK]: Add.
(event_handler_gdk): Adapt to new handle_one_xevent.
(handle_one_xevent): Remove bufp_r and numcharsp args.
Add hold_quit arg. Rework to use just one, local, inev
input_event. Store inev directly in fifo using
kbd_buffer_store_event_hold. Update count in one place.
Postpone call to gen_help_event until inev is stored; use new
local do_help for this.
Simplify handling of keysyms (consolidate common code). Fix bug
where count was updated with nchars instead of nbytes.
Remove local emacs_event in handing of ButtonPress event; just use
inev instead (so no reason to copy it later).
Remove `out' label. Rename label `ret' to `done'; add various
`goto done' to clarify code flow in deeply nested blocks.
(x_dispatch_event): Simplify as handle_one_xevent now calls
kbd_buffer_store_event itself.
(XTread_socket): Remove bufp_r and numcharsp args. Add hold_quit
arg. Call handle_one_xevent with new arglist. Store event from
x_session_check_input in fifo.
[USE_GTK]: Setup current_hold_quit.
Decrement handling_signal before unblocking input.
(x_initialize) [USE_GTK]: Initialize current_count.
Add hold_quit arg. Rework to use just one, local, inev
input_event. Store inev directly in fifo using
kbd_buffer_store_event_hold. Update count in one place.
Postpone call to gen_help_event until inev is stored; use new
local do_help for this.
Remove local emacs_event in handing of ButtonPress event; just use
inev instead (so no reason to copy it later).
(read_input_waiting): Adapt to new read_socket_hook interface.
Remove allocation and initialization of local input_event buffer,
as read_socket_hook stores events directly in fifo. Allocate and
initialize local hold_quit event to handle postponed quit event
(and store it if set by kbd_buffer_store_event_hold).
an event into kbd fifo, but with special handling of quit event;
a quit event is saved for later, and further events are discarded
until the saved quit event has been processed.
(kbd_buffer_store_event): Use kbd_buffer_store_event_hold.
(gen_help_event): Store help event in kbd fifo.
(NREAD_INPUT_EVENTS): Remove.
(read_avail_input): Adapt to new read_socket_hook interface.
Remove allocation and initialization of local input_event buffer,
as read_socket_hook stores events directly in fifo. Allocate and
initialize local hold_quit event to handle postponed quit event
(and store it if set by kbd_buffer_store_event_hold).
right-fringe similar to a display margin image. Specifically,
the characters having the fringe prop are no longer shown, and
we use IT_IMAGE/next_element_from_image with image_id = -1 to
do this. Set fringe bitmap face_id in it->face_id.
(produce_image_glyph): Handle image_id < 0 as "no image" case, but
still realize it->face (i.e. the fringe bitmap face).
(gdb-var-create-handler): Force speedbar-update-flag to be non-nil.
(gdb-var-delete): Make interactive (really).
(gdb-edit-value): Make non-interactive.
