Remove Title and Context bar when running Qtopia application

[dkt8154]

Dear guys,
I'm focus on making an qtopia application like todo list.
And I need it runs with full screen, that is, remove titile bar and context bar.
Could someone tell me how to do this ?
My Qtopia version is 4.2.1

you can control the widget decorations by specifying the window flags. (http://doc.trolltech.com/4.4/qt.html#WindowType-enum)
