newbie [Q] colors of dials and knobs

Forgive me if I am writing to the wrong list.
I am learning Qt/C++ and enjoying it a great deal.
I compiled the QWT demo's under WindowsXP and Ubuntu
and they look beautiful.

I have especially enjoyed the "radio" demo and I
wondered if it is possible to change the color of
the knobs and background from grey to something
else? where does one go to find the modules in
QWT or Qt where the colors are set?

thank you for your patience,
