Ubuntu + qt, how to update?

Question

Installed qt from ubuntu software center then can't find examples with qml, checked version, it shows that Using Qt version 4.6.2 in /usr/lib.

My question, how to update qt creator and qt? Is there any button on qt creator or function in make or qmake to update from 4.6.x to 4.7.xxx?

If I will download new version from official site I will duplicate all that things as qt creator, linguist, assinstent and designer, and fear to be confused which version I using in development.

For everyone asked this question: the situation has been changed. Currently there is the repository with the latest packages for Qt.

To add it, run: sudo add-apt-repository ppa:forumnokia/fn-ppa
