When examining Vselection_converter_out_alist, Fsafe_length() is no longer available. Use Flist_length instead. * emacs.c (main_1): Remove complex_vars_of_event_gtk(), there's no need for it. * event-gtk.c: * event-gtk.c (handle_map_event): Check for possible resizing on the map event too. * event-gtk.c (gtk_keysym_to_emacs_keysym): Use unicode_to_ichar(), rather than Funicode_to_char() with the wrong number of arguments. * event-gtk.c (gtk_event_to_emacs_event): * event-gtk.c (register_event_name): Don't strdup into the heap. Assert that every character in NAME is ASCII, use build_ascstring() with the result of the transformation, using Qutf_8 is an issue very early in the build. * event-gtk.c (register_event_names): Return Vgdk_event_names from this function, so the return value can be used in vars_of_event_gtk(). * event-gtk.c (vars_of_event_gtk): Use register_event_names() here. * event-gtk.c (complex_vars_of_event_gtk): Removed, no need for this, the relevant vars aren't actually complex. * faces.c (complex_vars_of_faces): Make some comments here a little more complete. * frame-gtk.c: * frame-gtk.c (gtk_recompute_cell_sizes): Make this take WIDTH_INCR and HEIGHT_INCR pointer output arguments, so callers can find out the effective character dimensions. * frame-gtk.c (gtk_set_initial_frame_size): Use this. * frame-gtk.c (gtk_set_frame_size): Use this. * frame-gtk.c (gtk_update_frame_external_traits): Use this. * frame.c: * frame.c (change_frame_size_1): Correct some comments here. * redisplay-gtk.c (XLIKE_output_eol_cursor): Some GTK version compatibility changes here. * redisplay-xlike-inc.c (XLIKE_text_width): Remove this completely, with Pango GTK and X11 have diverged sufficiently this doesn't help any more. * symsinit.h: Remove complex_vars_of_event_gtk() from this. diff -r f26c76a815e2 -r 9bdc40b8fb78 src/ChangeLog --- a/src/ChangeLog Sun Dec 17 11:05:35 2017 +0000 +++ b/src/ChangeLog Sun Dec 17 12:20:06 2017 +0000 ＠＠ -1,3 +1,55 ＠＠ +2017-12-17 Aidan Kehoe <kehoea(a)parhasard.net&gt; + + * console-gtk.c (gtk_perhaps_init_unseen_key_defaults): + Remove a buffer dependence here, use the default unicode + precedence list when converting a keysym's Unicode code point to + an XEmacs character. + * device-gtk.c (gtk_init_device): + On versions of GTK > 2.8.0, if gdk_screen_get_rgba_visual() + failed, try with gdk_visual_get_best(). + When examining Vselection_converter_out_alist, Fsafe_length() is + no longer available.
