annotate lwlib/lwlib-Xlw.c @ 5914:bd4d2c8ef9cc
Use the existing C-level line number cache within #'line-number.
src/ChangeLog addition:
2015-05-15 Aidan Kehoe <kehoea@parhasard.net>
* buffer.c:
* buffer.c (Fline_number): New C implementation, using the line
number cache of line-number.c, with a new optional BUFFER
argument.
* buffer.c (syms_of_buffer):
Make it available to Lisp.
* line-number.c (buffer_line_number):
New argument, RESPECT-NARROWING, describing whether to count from
the beginning of the visible region or from the beginning of the
buffer.
* line-number.h:
* line-number.h (buffer_line_number): Update its declaration.
* redisplay.c (window_line_number): Call it with the new argument.
lisp/ChangeLog addition:
2015-05-15 Aidan Kehoe <kehoea@parhasard.net>
* simple.el:
* simple.el (line-number): Moved to buffer.c; we have an existing
line number cache in C, it's a shame not to have it available.

| 328 While lwlib is a hairy crock, whoever wrote that seems to misunderstand | |
| 329 Falk's tab control widget. The tab control widget has *two* kinds of | |
| 330 children: *widgets*, which all occupy a *single* pane below the row of | |
| 331 tabs---this is where the labels created in build_tabs_in_widget go, and | |
| 332 *gadgets*, the tabs themselves, which do *not* draw themselves, but | |
| 333 rather are drawn by the control. In fact, in XEmacs the true widget | |
| 334 children are *never* visible! So this case is not a problem in the | |
| 335 design of lwlib, but rather of Falk's widget. -- sjt */ | |
