I finally found a way to change the kde4 proxy automatically based on class of ip address i get on available network interface.
I already found a script from google to do that for gnome.
And now found a KDE3 script which had to be modified to do a KDE4 DBUS message to make applications reread the settings.
The info was especially hard to find on the net. Reproducing both scripts below.
Put below in /etc/NetworkManager/dispatcher.d/02proxy
Make sure you make appropriate changes to USERNAME and YOURPROXY etc. (Click read more to find the scripts)
#!/bin/bash
# The script for automatically setting the proxy server depending on location.
# Put it under /etc/NetworkManager/dispatcher.d/ and modify for your needs.

function gconf() {
sudo -E -u $USER gconftool-2 "$@"
}
INTERFACE=$1
COMMAND=$2
# init DBUS connection string in order to reach gconfd
XENV=`xargs -n 1 -0 echo </proc/$(pidof gnome-session)/environ`
eval export `echo "$XENV" | fgrep DBUS_SESSION_BUS_ADDRESS=`
if [ $COMMAND = 'up' ]; then
if nm-tool | fgrep $WORK_IP; then
echo work found
gconf --type string --set /system/proxy/mode "manual"
gconf --type bool --set /system/http_proxy/use_http_proxy "true"
gconf --type string --set /system/http_proxy/host "<YOURPROXY>"
gconf --type int --set /system/http_proxy/port "8080"
gconf --type bool --set /system/http_proxy/use_same_proxy "true"
su $USER -c "/home/bain/scripts/kproxyswitch.sh on"
else
gconf --type string --set /system/proxy/mode "none"
gconf --type bool --set /system/http_proxy/use_http_proxy "false"
gconf --type string --set /system/http_proxy/host ""
gconf --type bool --set /system/http_proxy/use_authentication "false"
su $USER -c "/home/bain/scripts/kproxyswitch.sh off"

fi
Put this somewhere on the system and make sure the script above uses the same path
