[kde] Eclipse IDE in KDE looks ugly

view story

http://ubuntuforums.org – Installed Ubuntu 12.10 and KDE as my primary desktop manager. My system is very stable and I have no issues so far. Just a minor UI glitch. My Eclipse IDE (also Chrome) looks ugly and dont behave to have KDE application L&F. Google search says, "GTK-Qt Theme Engine is a plugin for GTK that allows GTK applications to use Qt widget styles" Not sure how to install this. Really appreciate your help on this. (Hardware)
