From 851f665725581d02d48ffbca50240cda44d698d4 Mon Sep 17 00:00:00 2001 From: Sedat Dilek Date: Sat, 15 Jun 2013 11:07:35 +0200 Subject: kconfig/lxdialog: Add definitions for mininimum (re)size values Commit c8dc68ad0fbd ("kconfig/lxdialog: support resize") added support for resizing, but forgot to collect all hardcoded values at one single place. Also add a definition for the check for a minimum screen/window size of 80x19. [ ChangeLog v3: * Rename MENU_{HEIGTH,WIDTH}_MIN -> MENUBOX_{HEIGTH,WIDTH}_MIN ChangeLog v2: * Rename WIN_{HEIGTH,WIDTH}_MIN -> WINDOW_{HEIGTH,WIDTH}_MIN * Mention the check for a minimum screen/window size in the changelog * Add a comment above the block of new definitions ] Signed-off-by: Sedat Dilek Acked-by: Wang YanQing Tested-by: "Yann E.

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().
