From c8dc68ad0fbd934e78e913b8a8d7b45945db4930 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sat, 29 Jul 2006 22:48:57 +0200 Subject: kconfig/lxdialog: support resize In all dialogs now properly catch KEY_RESIZE and take proper action. In mconf try to behave sensibly when a dialog routine returns -ERRDISPLAYTOOSMALL. The original check for a screnn size of 80x19 is kept for now. It may make sense to remove it later, but thats anyway what much text is adjusted for.
