more subwindow/widget fiddling

This patch allows for the normal use of gui_item keywords in widget definitions i.e. [button :descriptor "ok" :active t] rather than [button :descriptor ["ok" :active t]]. It also provides support for glyphs in buttons (support for others would be possible but I don't know how much meaning it has). see glyph-tests.el for details. The patch also nukes all remaining warnings from the cygwin build. I ought to try porting some of the wid-edit.el stuff to native widgets but the size of the task defeats me at the moment. andy 1998-12-28 Andy Piper <andy(a)xemacs.org&gt; * glyphs-msw.c (mswindows_button_instantiate): cope with buttons that have an image provided. * glyphs.h: add Q_image decl. * glyphs-widget.c new functionality allowing images in widgets. (check_valid_glyph_or_image): new function to validate glyphs passed in through :image. (widget_normalize): new function. convert :image parameters into real glyphs if not already so. (widget_instantiate_1): mess with size parameters to be similar to :image if provided. (syms_of_glyphs_widget): new keyword :image. (image_instantiator_format_create_glyphs_widget): normalize buttons and allow :image. 1998-12-27 Andy Piper <andy(a)xemacs.org&gt; * frame-msw.c (mswindows_init_frame_1): warning elimination. * glyphs-widget.c (check_valid_anything): no-op function. (check_valid_callback): check callbacks in gui_items. (check_valid_symbol): as it sounds. (check_valid_string_or_vector): ditto. (widget_validate): modified for descriptors that are vectors or sequences of keyword/val pairs. (widget_instantiate_1): ditto. (image_instantiator_format_create_glyphs_widget): allow gui_item keywords in the instantiator. * gui.c (gui_parse_item_keywords_internal): renamed from gui_parse_item_keywords but taking error behaviour. (gui_parse_item_keywords): use it. (gui_parse_item_keywords_no_errors): ditto. (gui_item_add_keyval_pair): add Error_behavior flag and only signal invalid keywords if required. * gui.h: new gui signatures. * menubar.c (menu_parse_submenu_keywords): use new gui_item_add_keyval_pair signature. * s/cygwin32.h: modify PTY_ITERATION to eliminate warnings. --------------------------------------------------------------------------- " .sigs are like your face - rarely seen by you and uglier than you think" Dr Andy Piper, Technical Architect, Parallax Solutions Ltd mail: andyp(a)parallax.co.uk web: www.parallax.co.uk/~andyp
