Dynamic layouts part #1

This patch changes geometry calculation of widgets to be dynamic, this has a number of desirable side-effects including making widget updates more asynchronous. part #2 will be actually fixing the layout widget to lay out its children dynamically and intelligently. I will apply this tomorrow. andy 2000-01-08 Andy Piper <andy(a)xemacs.org&gt; * event-msw.c (mswindows_wnd_proc): don't need to check for widget face anymore. * frame.c (change_frame_size_1): use new glyph_* signatures.

(add_margin_runes): ditto. (create_left_glyph_block): ditto. (create_right_glyph_block): ditto. (redisplay_window): ditto. * redisplay-output.c (redisplay_output_layout): Use modified glyph_* signatures. * glyphs.h: (struct image_instantiator_methods): change signature of query_geometry and layout. (struct Lisp_Image_Instance): Clean up fields for dynamic geometry calculations. (struct expose_ignore): change field types. (struct subwindow_cachel): ditto. declare new functions and accessor macros. * glyphs.c: (instantiate_image_instantiator): assign glyph when creating the image instance. (image_instance_hash): fixup for new and deleted fields. (image_instance_equal): ditto. (mark_image_instance): ditto. (print_image_instance): ditto. (allocate_image_instance): zero width and height. assign attached glyph. mark as dirty for future layout. (make_image_instance_1): pass Qnil as the glyph its attached to. (Fimage_instance_height): simply return the height. (Fimage_instance_width): simply return the width. (image_instance_query_geometry): new function. query the image instance's geometry by wiring through to format and device specific methods. fallback on the existing geometry. (image_instance_layout): new function. layout the image instance by querying its geometry and then wiring through to format and device specific methods. (query_string_geometry): new function to decide the bounding box of a string. text glyph geometry calculations moved here. (query_string_font): new function. find out the font for a given string in a given face. (text_query_geometry): return geometry based on quert_string_geometry. (formatted_string_instantiate): call string_instantiate. (image_instantiate): put strings in the per-window cache. Feed the glyph to the instantiated image instance. (glyph_height_internal): deleted. (glyph_width): simply return the required dimension. re-layout if the instance is dirty. Remove references to face_index and frame_face which were only used for strings. (glyph_ascent): ditto. (glyph_descent): ditto. (glyph_height): ditto. (Fglyph_width): use new glyph_width function. (Fglyph_ascent): use new glyph_ascent function. (Fglyph_descent): use new glyph_descent function. (Fglyph_height): use new glyph_height function. (glyph_property_was_changed): (glyph_image_instance_maybe): new function to possible create an image instance from a glyph if we don't have one already. (glyph_dirty_p): use it. (glyph_layout): new function for laying out a glyph. (glyph_query_geometry): new function for finding out the desired geometry of a glyph. (update_glyph_cachel_data): use new glyph_* signatures. (update_subwindow): call resize_subwindow. (map_subwindow): call update_subwindow if the image is dirty. (subwindow_instantiate): add comment. (Fresize_subwindow): don't actually resize the window, just record the values and let update_subwindow handle it. (Fglyph_animated_timeout_handler): use MARK_IMAGE_INSTANCE_CHANGED. (image_instantiator_format_create): declare things with query_geometry and layout functions. * glyphs-x.c: (x_update_subwindow): remove widget sizing. (update_widget_face): use query_string_font. (x_widget_set_property): don't return Qt when setting is succesful. (x_combo_box_instantiate): call widget_instantiate rather than widget_instantiate_1. * glyphs-widget.c: (widget_face_font_info): deleted. (widget_text_to_pixel_conversion): deleted. (widget_set_property): make sure the new text gets propagated to the image instance. (widget_layout): new function. wire through to device and format specific methods. (widget_query_geometry): new function. wire through to device and format specific methods. fallback on geometry of widget text. (initialize_widget_image_instance): fixup new fields. (widget_instantiate_1): deleted. (tree_view_instantiate): deleted. (tree_view_query_geometry): new function. returns desired sizing of tree view. (tab_control_instantiate): deleted. (tab_control_query_geometry): new function. returns desired sizing of tab. (widget_instantiate): subsume widget_instantiate_1. Fixup geometry things in the light of dynamic layout. (static_instantiate): deleted. (layout_instantiate): use new glyph_* signatures. (image_instantiator_format_create_glyphs_widget): fixup query_geometry and layout declarations for various widgets. * glyphs-msw.c: (mswindows_widget_instantiate): add comment. (mswindows_button_instantiate): use query_string_font for geometry calculations. (mswindows_update_subwindow): ditto. (mswindows_combo_box_instantiate): fixup for new geometry management. (mswindows_widget_set_property): Don't return Qt so that other methods can be called. * gutter-items.el (update-tab-in-gutter): remove resize-subwindow calls. (remove-buffer-from-gutter-tab): ditto. -------------------------------------------------------------- Dr Andy Piper Senior Consultant Architect, BEA Systems Ltd
