How can I get those Embedded Widgets in Qt Creator

Hi,
I would like to design a user interface using embedded widgets. What do I have to do to get those widgets from that nice demo (http://qt.nokia.com/developer/embedded-widget-demos, source code available) into my Widget Selection Window in Qt Creator?

Do I have to recompile my creator with the qt embedded library?

Thank you for your help, I really could not find a documentation about how to comfortably design ui with non standard widgets.:confused:

Spikey

Bump. I would also like to know.

any hints guys??
Thanks

The exact same way you would use for any other widgets - implement a Designer plugin for them.
