(1) Run `window-configuration-change-hook' if and only if at least one window was deleted or created or shows another buffer since last redisplay. (2) Run `window-size-change-functions' if and only if at least one window changed its size since last redisplay (in a few cases `window-size-change-functions' will also run when no window changed its size). (3) Provide two functions `window-pixel-height-before-size-change' and `window-pixel-width-before-size-change' that allow to easily detect which window changed size. * src/frame.h (struct frame): New boolean member window_configuration_changed. (FRAME_WINDOW_SIZES_CHANGED): Remove macro. (FRAME_WINDOW_CONFIGURATION_CHANGED): New macro. * src/frame.c (adjust_frame_size): Don't run `window-configuration-change-hook'. * src/window.h (struct window): New fields pixel_width_before_size_change and pixel_height_before_size_change. (WINDOW_INTERNAL_P): New macro. * src/window.c (Fwindow_pixel_width_before_size_change) (Fwindow_pixel_height_before_size_change): New functions. (Fdelete_other_windows_internal, Fwindow_resize_apply) (resize_frame_windows, Fsplit_window_internal) (Fdelete_window_internal, grow_mini_window) (shrink_mini_window, Fresize_mini_window_internal): Don't call FRAME_WINDOW_SIZES_CHANGED. (window_size_changed, window_set_before_size_change_sizes) (run_window_size_change_functions): New functions. (make_window): Initialize pixel_width_before_size_change and pixel_height_before_size_change. (Fdelete_window_internal): Don't call run_window_configuration_change_hook. (struct saved_window): Add pixel_height_before_size_change and pixel_width_before_size_change. (Fset_window_configuration): Try to identify window configuration changes correctly so run_window_configuration_change_hook and run_window_size_change_functions run only if configuration and size really changed. (save_window_save): Set the pixel_height_before_size_change and pixel_width_before_size_change fields. (Vwindow_size_change_functions): Move here definiton from xdisp.c. * src/xdisp.c (prepare_menu_bars, redisplay_internal): Call run_window_size_change_functions. (Vwindow_size_change_functions): Move definition to window.c. * src/xfns.c (x_set_menu_bar_lines): Don't call run_window_configuration_change_hook. * doc/lispref/windows.texi (Window Sizes): Document new functions `window-pixel-height-before-size-change' and `window-pixel-width-before-size-change'. (Window Configurations): Mention that this may trigger execution of `window-size-change-functions' although no window changed size. (Window Hooks): Update descriptions of `window-size-change-functions' and `window-configuration-change-hook'. |

README for the Emacs Lisp Reference Manual.
* This directory contains the texinfo source files for the Emacs Lisp
Reference Manual.
* Report bugs in the Lisp Manual (or in Emacs) using M-x report-emacs-bug.
To ask questions, use the help-gnu-emacs mailing list.
* The Emacs Lisp Reference Manual is quite large. It totals around
1100 pages in smallbook format; the info files total around 3.0 megabytes.
* You can format this manual for Info, for printing hardcopy using TeX,
or for HTML.
* You can buy nicely printed copies from the Free Software Foundation.
Buying a manual from the Free Software Foundation helps support our GNU
development work. See <http://shop.fsf.org/>.
(At time of writing, this manual is out of print.)
* The master file for formatting this manual for Tex is called 'elisp.texi'.
It contains @include commands to include all the chapters that make up
the manual.
* This distribution contains a Makefile that you can use with GNU Make.
** To make an Info file, you need to install Texinfo, then run 'make info'.
** Use 'make elisp.pdf' or 'make elisp.html' to create PDF or HTML versions.
