X-Git-Tag: tce~961 X-Git-Url: https://plomlompom.com/repos/%22https:/validator.w3.org/%7B%7Bdb.prefix%7D%7D/todos?a=commitdiff_plain;h=adce487b47febb1d63e6ab6f50388e332c42ea91;p=plomrogue Re-modelled draw_kb_view() on draw_titled_keybinding_list() model, lots of re-factorisation among those two; also added "(none)" display for empty keybinding lists in keybinding configuration windows. --- diff --git a/src/draw_wins.c b/src/draw_wins.c index 5b6de1b..89a3c63 100644 --- a/src/draw_wins.c +++ b/src/draw_wins.c @@ -6,7 +6,7 @@ #include /* for strlen() */ #include /* for mvwaddch() */ #include "windows.h" /* for structs Win, Frame, for draw_scroll_hint() */ -#include "misc.h" /* for center_offset() */ +#include "misc.h" /* for center_offset(), try_malloc() */ #include "keybindings.h" /* for struct KeyBinding, for get_name_to_keycode() */ #include "map_objects.h" /* for structs MapObj, Player */ #include "map.h" /* for Map struct */ @@ -23,8 +23,12 @@ static void draw_with_linebreaks(struct Win * win, char * text, uint16_t start_y);
