widget patches & friends.

This clears the backlog in my local environment: - FIxes tab font change problems under X - Fixes widget copying problems - Syncs with the latest Tabs version - Starts on layouts. andy 1999-12-21 Andy Piper <andy(a)xemacs.org&gt; * redisplay.c (redisplay_frame): check for faces changed when reseting subwindow caches. * glyphs.h (struct ii_keyword_entry): add copy_p. (struct image_instantiator_methods): add query_geometry_method and layout_children_method. (IIFORMAT_VALID_GENERIC_KEYWORD): new macro to take into account copying characteristics of keywords. (IIFORMAT_VALID_NONCOPY_KEYWORD): new macro for defining keywords whose arguments should not be copied by the specifier code. (image_instance_geometry): new enum for layouts. (struct Lisp_Image_Instance): re-jig for layouts and update macros. * glyphs.c (string_instantiate): rename variables. (image_instantiate): add strings to those widgets that are instantiated per-window. (image_copy_vector_instantiator): new function for copying glyph specifier instantiators. (image_copy_instantiator): ditto. * glyphs-x.c (x_update_subwindow): use new face update functions. (update_widget_face): update to use new lwlib arg functions. (update_tab_widget_face): new function for updating tab control label faces. (x_widget_instantiate): use new face update functions and new lwlib arg functions. (x_tab_control_instantiate): ditto. (x_tab_control_set_property): ditto. * glyphs-widget.c (VALID_GUI_KEYWORDS): use NONCOPY keyword for callbacks and other things that could recurse. (VALID_GUI_KEYWORDS): * event-msw.c: fix cpp stuff for cygwin < b20. * config.h.in: move uid_t and friends to before the s&m files so that they can be used there. * Makefile.in.in (debug-temacs): new target that adds emacs environment before invoking gdb. * lwlib.h (_widget_args): new structure for holding widget args. It is reference counted so that we don't have to copy Xt args. (_widget_value): remove widget args. Add reference to widget_args. * lwlib.c (free_widget_value_contents): free widget args using free_widget_value_args. * lwlib-Xaw.c (xaw_update_one_widget): use new arg packet. (xaw_update_one_widget): use XtIsSubclass for determining labels. * lwlib.c (lw_add_value_args_to_args): modify to use our reference counted arg packet. (lw_add_widget_value_arg): new function. Add an arg to the arg packet. (free_widget_value_args): new function. Remove a reference counted arg packet. (lw_copy_widget_value_args): new function. Copy reference counted arg packet. (merge_widget_value_args): new function. Do a merge of widget args. (merge_widget_value): use it. (copy_widget_value_tree): copy widget args using reference counting, since we can't easily copy the args we have been given. * specifier.h (struct specifier_methods): add copy_instantiator_method. * specifier.c (build_up_processed_list): use copy_instantiator_method if defined. 1999-12-08 Andy Piper <andy(a)xemacs.org&gt; * xlwtabs.c: sync with Tabs 2.1. * xlwtabP.h: ditto. 1999-11-25 Andy Piper <andy(a)xemacs.org&gt; * cus-edit.el (custom-buffer-create-buttons): Use native widgets for buttons. -------------------------------------------------------------- Dr Andy Piper Senior Consultant Architect, BEA Systems Ltd
