Dynamic size spec for widgets

This patch allows pixel sizes to be specified dynamically for widgets. A side effect is that tabs can be specified with the full gutter width, hence fixing tab color problems. andy 2000-02-23 Andy Piper <andy(a)xemacs.org&gt; * glyphs.c (subwindow_instantiate): allow for dynamic size specs. * glyphs-widget.c (check_valid_int_or_function): new function. (image_instantiator_combo_box): use it. (image_instantiator_scrollbar): ditto. (image_instantiator_layout): ditto. * gutter-items.el (add-tab-to-gutter): specify dimensions dynamically. * glyphs.c: add dynamic width and height elements. (image_instance_equal): ditto. * glyphs-widget.c (widget_query_geometry): calculate width and height dynamically if required. (initialize_widget_image_instance): initialize dynamic dimensions. (widget_instantiate): pick-up dynamic dimensions. * glyphs.h (struct Lisp_Image_Instance): add width and height for dynamic determination. Add appropriate macros. * gutter.h (WINDOW_GUTTER_BORDER_WIDTH): make non-integer dimensions safe. (WINDOW_GUTTER_SIZE): ditto. (WINDOW_GUTTER_SIZE_INTERNAL): ditto. * redisplay-msw.c (get_frame_compdc): gcc can't cope with this inline. (get_frame_dc): ditto. 2000-02-22 Andy Piper <andy(a)xemacs.org&gt; * redisplay.h (GLOBAL_RESET_CHANGED_FLAGS): don't reset faces here. -------------------------------------------------------------- Dr Andy Piper Senior Consultant Architect, BEA Systems Ltd
