From 930b2c4a7f222e15e6493d5bbb8fd90e681d2626 Mon Sep 17 00:00:00 2001 From: Roberto E. Vargas Caballero Date: Mon, 3 Sep 2012 21:52:34 +0200 Subject: [PATCH] Force redisplay of all lines in DECSCNM When it is called DECSCNM all lines become dirty, because it is necessary redraw all lines for getting the new colors. It is easy see the problem running 'echo ^[[?5h'. In order to get a correct flash when running tput flash is necessary wait after DECSCNM, until the changes are displayed, because in other case the switch between reverse on/reverse off will be too much fast and nothing will happen. --- st.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) --- st.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/st.c b/st.c index fde0493..193db5e 100644 --- a/st.c +++ b/st.c @@ -54,6 +54,7 @@ #define SELECT_TIMEOUT (20*1000) /* 20 ms */ #define DRAW_TIMEOUT (20*1000) /* 20 ms */ +#define REDRAW_TIMEOUT (80*1000) /* 80 ms */ #define SERRNO strerror(errno) #define MIN(a, b) ((a) < (b) ?
