xlike cleanup, documentation -------------------- ChangeLog entries follow: -------------------- man/ChangeLog addition: 2010-02-03 Ben Wing <ben@xemacs.org> * internals/internals.texi (Top): * internals/internals.texi (Evaluation; Stack Frames; Bindings): * internals/internals.texi (Ben's README): * internals/internals.texi (Consoles; Devices; Frames; Windows): * internals/internals.texi (Window Hierarchy): * internals/internals.texi (The Window Object): * internals/internals.texi (Modules for the Basic Displayable Lisp Objects): * internals/internals.texi (Window-System Support): * internals/internals.texi (Creating a Window-System Type): * internals/internals.texi (Discussion -- Garbage Collection): Update the part at the top about how to maintain the file with more tips. Add a chapter on "window-system support" describing in a general way how the support for different window systems/device types works, including the separation between device-independent and device-dependent parts, device methods, the specific device types and the "xlike" pseudo-type. src/ChangeLog addition: 2010-02-03 Ben Wing <ben@xemacs.org> * Makefile.in.in: * Makefile.in.in (x_objs): * Makefile.in.in (gtk_gui_objs): * console-xlike-inc.h: * depend: * device-x.c: * emacs.c: * gccache-gtk.h: * gccache-gtk.h (gc_cache_lookup): * gccache-x.c: * gccache-x.c (GCCACHE_HASH): * gccache-x.h: * toolbar-gtk.c: * toolbar-gtk.c (gtk_initialize_frame_toolbars): * toolbar-x.c: * toolbar-x.c (x_initialize_frame_toolbars): * toolbar-xlike.c: * toolbar-xlike.c (xlike_draw_blank_toolbar_button): * toolbar-xlike.c (xlike_output_toolbar_button): * toolbar-xlike.c (xlike_get_button_size): * toolbar-xlike.c (XLIKE_OUTPUT_BUTTONS_LOOP): * toolbar-xlike.c (xlike_output_toolbar): * toolbar-xlike.c (xlike_clear_toolbar): * toolbar-xlike.c (xlike_output_frame_toolbars): * toolbar-xlike.c (xlike_clear_frame_toolbars): * toolbar-xlike.c (xlike_redraw_exposed_toolbar): * toolbar-xlike.c (xlike_redraw_exposed_toolbars): * toolbar-xlike.c (xlike_redraw_frame_toolbars): * toolbar-xlike.h: * toolbar-xlike.h (xlike_clear_frame_toolbars): Rename some files to make them consistent with general naming rules: xgccache.c -> gccache-x.c xgccache.h -> gccache-x.h toolbar-common.c -> toolbar-xlike.c toolbar-common.h -> toolbar-xlike.h Fix include-file references. Also change the names of functions in now-named toolbar-xlike.c to be xlike_foo() instead of common_foo(). Add a longish comment in console-xlike-inc.h describing the "xlike" system, how it works and what the various files are used for.
