From 3b354c557c7a6fcac099b3a20b308853fe596183 Mon Sep 17 00:00:00 2001 From: Karsten Wiese Date: Wed, 13 Dec 2006 00:34:08 -0800 Subject: [PATCH] [PATCH] kconfig: add "void conf_set_changed_callback(void (*fn)(void))", use it in qconf.cc Added function sets "void (*conf_changed_callback)(void)". Call it, if .config's changed state changes. Use above in qconf.cc to set gui's save-widget's sensitvity.
