You can either upgrade to a newer Ubuntu release (the last one contains Qt 4.7.0), find a backport repository with Qt 4.7 compiled for your release or download the source tarball and build Qt yourself, it's very simple.

the method you suggest needs to install qt from scratch but i want just up gradation
any shorter way?
means a system that modifies and adds the functionalities in the already installed version QT 4.5 according to the latest version QT 4.7.1
It doesn't work that way. You really have to upgrade to version 4.7 (that is replace 4.5 with 4.7 in your system) and not download a bunch of files and think your 4.5 will suddenly have the capabilities of 4.7.
thanks for clarifying my concepts
