[xemacs-hg @ 2002-12-08 10:24:33 by michaels] 2002-12-02 Mike Sperber <mike@xemacs.org> * The Great Window Configuration rewrite: Re-implement window configuration functionality in Emacs Lisp. * window.h (Fcurrent_window_configuration): Don't export anymore. (Qcurrent_window_configuration): Declare. (Qset_window_configuration): Declare. * event-stream.c (execute_help_form): * bytecode.c (execute_rare_opcode): Call out to Lisp to save window excursion. * window.c (Qcurrent_window_configuration): Declare. (Qwindow_configurationp): (Vwindow_configuration_free_list): (Qset_window_configuration): (Qtemp_buffer_show_hook): (struct saved_window): (struct window_config): (SAVED_WINDOW_N): (XWINDOW_CONFIGURATION): (wrap_window_configuration): (WINDOW_CONFIGURATIONP): (CHECK_WINDOW_CONFIGURATION): (mark_window_config): (sizeof_window_config_for_n_windows): (sizeof_window_config): (print_window_config): (saved_window_equal): (window_config_equal): (Fwindow_configuration_p): (mark_windows_in_use_closure): (mark_windows_in_use): (free_window_configuration): (Fset_window_configuration): (count_windows): (saved_window_index): (save_window_save): (Fcurrent_window_configuration): (Fsave_window_excursion): Remove. (mark_window_as_deleted): Rectify comment about `set-window-configuration'. (Fset_window_buffer): Reinstate code not activated because of old implementation of window configurations. (temp_output_buffer_show): Don't run `temp-buffer-show-hook' anymore---this wasn't supposed to happen anyway according to the documentation of `temp-buffer-show-function'. (reinit_vars_of_window): Don't do the window configuration stuff no more (vars_of_window): Don't set up `temp-buffer-show-hook' any more. 2002-12-02 Mike Sperber <mike@xemacs.org> * The Great Window Configuration rewrite: Re-implement window configuration functionality in Emacs Lisp. * window-xemacs.el (current-window-configuration): (set-window-configuration): (plus many functions they depend on) Re-implement window configurations in Emacs Lisp.
