redeem_scrollbar_hook, judge_scrollbars_hook): Removed dumbo
"externs" from these. They're supposed to be real definitions.
* termhooks.h (mouse_position_hook): Doc fix.
(set_vertical_scrollbar_hook): This doesn't return anything any
more, and doesn't take a struct scrollbar * argument any more.
(condemn_scrollbars_hook, redeem_scrollbar_hook,
judge_scrollbars_hook): Doc fixes.
* term.c (mouse_position_hook): Doc fix.
(set_vertical_scrollbar_hook): This doesn't return
anything any more. Doc fixes.
* keyboard.c (kbd_buffer_get_event): Receive the scrollbar's
window from *mouse_position_hook and pass it to
make_lispy_movement, instead of working with a pointer to a struct
scrollbar.
(make_lispy_event): We don't need a window_from_scrollbar function
anymore; we are given the window directly in *EVENT.
Unify the code which generates
text-area mouse clicks and scrollbar clicks; use the same code to
distinguish clicks from drags on the scrollbar as in the text area.
Distinguish clicks from drags by storing a copy of the lispy
position list returned as part of the event.
(button_down_location): Make this a lisp vector, rather than an
array of random structures.
(struct mouse_position): Remove this; it's been replaced by a lisp
list.
(make_lispy_movement): Accept the scrollbar's window as a
parameter, rather than the scrollbar itself.
If FRAME is zero, assume that the other arguments are garbage.
(syms_of_keyboard): No need to staticpro each window of
button_down_location now; just initialize and staticpro it.
* window.c (window_from_scrollbar): Function deleted; no longer
needed.
* xdisp.c (redisplay_window): Just pass the window to
set_vertical_scrollbar hook; don't pass the scrollbar object too.
* xterm.c (XTmouse_position): Don't return a pointer to the
scrollbar for scrollbar motion; instead, return the scrollbar's
window.
`has_vertical_scrollbars'.
(FRAME_CAN_HAVE_SCROLLBARS, FRAME_HAS_VERTICAL_SCROLLBARS): New
accessors, for both the MULTI_FRAME and non-MULTI_FRAME.
(VERTICAL_SCROLLBAR_WIDTH, WINDOW_VERTICAL_SCROLLBAR,
WINDOW_VERTICAL_SCROLLBAR_COLUMN,
WINDOW_VERTICAL_SCROLLBAR_HEIGHT): New macros.
* window.h (struct window): New field `vertical_scrollbar'.
* xterm.h (struct x_display): vertical_scrollbars,
judge_timestamp, vertical_scrollbar_extra: New fields.
(struct scrollbar): New struct.
(VERTICAL_SCROLLBAR_PIXEL_WIDTH, VERTICAL_SCROLLBAR_PIXEL_HEIGHT,
VERTICAL_SCROLLBAR_LEFT_BORDER, VERTICAL_SCROLLBAR_RIGHT_BORDER,
VERTICAL_SCROLLBAR_TOP_BORDER, VERTICAL_SCROLLBAR_BOTTOM_BORDER,
CHAR_TO_PIXEL_WIDTH, CHAR_TO_PIXEL_HEIGHT, PIXEL_TO_CHAR_WIDTH,
PIXEL_TO_CHAR_HEIGHT): New accessors and macros.
* frame.c (make_frame): Initialize the `can_have_scrollbars' and
`has_vertical_scrollbars' fields of the frame.
* term.c (term_init): Note that TERMCAP terminals don't support
scrollbars.
(mouse_position_hook): Document new args.
(set_vertical_scrollbar_hook, condemn_scrollbars_hook,
redeem_scrollbar_hook, judge_scrollbars_hook): New hooks.
* termhooks.h: Declare and document them.
(enum scrollbar_part): New type.
(struct input_event): Describe the new form of the scrollbar_click
event type. Change `part' from a Lisp_Object to an enum
scrollbar_part. Add a new field `scrollbar'.
* keyboard.c (kbd_buffer_get_event): Pass appropriate new
parameters to *mouse_position_hook, and make_lispy_movement.
* xfns.c (x_set_vertical_scrollbar): New function.
(x_figure_window_size): Use new macros to calculate frame size.
(Fx_create_frame): Note that X Windows frames do support scroll
bars. Default to "yes".
* xterm.c: #include <X11/cursorfont.h> and "window.h".
(x_vertical_scrollbar_cursor): New variable.
(x_term_init): Initialize it.
(last_mouse_bar, last_mouse_bar_frame, last_mouse_part,
last_mouse_scroll_range_start, last_mouse_scroll_range_end): New
variables.
(XTmouse_position): Use them to return scrollbar movement events.
Take new arguments, for that purpose.
(x_window_to_scrollbar, x_scrollbar_create,
x_scrollbar_set_handle, x_scrollbar_remove, x_scrollbar_move,
XTset_scrollbar, XTcondemn_scrollbars, XTredeem_scrollbar,
XTjudge_scrollbars, x_scrollbar_expose,
x_scrollbar_background_expose, x_scrollbar_handle_click,
x_scrollbar_handle_motion): New functions to implement scrollbars.
(x_term_init): Set the termhooks.h hooks to point to them.
(x_set_window_size): Use new macros to calculate frame size. Set
vertical_scrollbar_extra field.
(x_make_frame_visible): Use the frame accessor
FRAME_HAS_VERTICAL_SCROLLBARS to decide if we need to map the
frame's subwindows as well.
(XTread_socket): Use new size-calculation macros from xterm.h when
processing ConfigureNotify events.
(x_wm_set_size_hint): Use PIXEL_TO_CHAR_WIDTH and
PIXEL_TO_CHAR_HEIGHT macros.
* ymakefile (xdisp.o): This now depends on termhooks.h.
(xterm.o): This now depends on window.h.
empty string, which means that you can't have constant
initialized arrays inside a function. So move the `keys' array
outside of the function.
* term.c (keys): Include definitions for "K2" (the center key on
an IBM keypad), "F1" (F11), and "F2" (F12). Handle "k0" and "k;"
specially; see the code for details.
* term.c (clear_end_of_line): Remember that on some systems,
"static" gets defined to be the null string, so we can't declare
an array to be static and then initialize it. Since the array in
question (buf) is only one element long, just make it a scalar
rather than an array; it can then be initialized, even if it's
not static.
