[Qt-interest] How can I hide qpe's top-bar and bottom-bar?

[Kermit Mei]

Dear all,

    I launch my programs with qpe, but qpe always shows two bars at the
top and bottom, just like GNOME's desktop-bars. 
    I hope that my program can show full screen, how can I implement it?
Can QWidget::showFullScreen() do it? I have many different UI process to
run, it's a tedious work for me to add showFullScreen() to every
process. Is there any better way to set qpe itself to do it?


Thanks
