From 4f2de3e19983dafca264b672152b36e4962ca1c3 Mon Sep 17 00:00:00 2001 From: Dirk Gouders Date: Sun, 12 May 2013 12:30:49 +0200 Subject: mconf: use function calls instead of ncurses' variables LINES and COLS According to the documentation [1], LINES and COLS are initialized by initscr(); it does not say anything about the behavior when windows are resized. Do not rely on the current implementation of ncurses that updates these variables on resize, but use the propper function calls to get window dimensions. init_dialog() could make use of the variables, but for the sake of consistency we do not change it's current use of the macro getmaxyx().
