From 613e8c91f082ca3cb64aa10063d3254100deac84 Mon Sep 17 00:00:00 2001 From: Robin Haberkorn Date: Tue, 9 Dec 2014 02:46:34 +0100 Subject: Curses: support cycling through long lists of possible auto-completions and optimized screen refreshing/redrawing * pressing e.g. TAB when the popup is showing a list of auto-completions will show the next page, eventually beginning at the first one again. * do not redraw curses windows in the UI methods directly. this resulted in flickering during command-line editing macros and ordinary macro calls because the physical screen was updated immediately. Instead, window refreshing and updated is done centrally in event_loop_iter() only after a key has been processed. Also we use wnoutrefresh() and doupdate() to send as little to the terminal (emulator) as possible. --- src/interface-curses.h | 19 +++++++++++++++---- 1 file changed, 15 insertions(+), 4 deletions(-) (limited to 'src/interface-curses.h') diff --git a/src/interface-curses.h b/src/interface-curses.h index 35f7edb..70e5300 100644 --- a/src/interface-curses.h +++ b/src/interface-curses.h @@ -80,11 +80,16 @@ typedef class InterfaceCurses : public Interface { struct Popup { WINDOW *window; - GSList *list; - gint longest; - gint length; + GSList *list; /**! list of popup entries */ + gint longest; /**! size of longest entry */ + gint length; /**! total number of popup entries */ - Popup() : window(NULL), list(NULL), longest(0), length(0) {} + GSList *cur_list; /**! next entry to display */ + gint cur_entry; /**! next entry to display (position) */ + + Popup() : window(NULL), list(NULL), + longest(3), length(0), + cur_list(NULL), cur_entry(0) {} ~Popup(); } popup; @@ -122,6 +127,12 @@ public: const gchar *name, bool highlight = false); /* implementation of Interface::popup_show() */ void popup_show_impl(void); + /* implementation of Interface::popup_is_shown() */ + inline bool + popup_is_shown_impl(void) + { + return popup.window != NULL; + } /* implementation of Interface::popup_clear() */ void popup_clear_impl(void); -- cgit v1.2.3
