Thank you, Mr King.

But I don't think this question is about how to program, but how to
configure qpe environment. 

To remove title Bar and context Bar, it just need to modify the file
qtopia.conf in /opt/Qtopia/etc/themes.

Now, I miss a new problem, that is qpe's desktop widget which returned
by QApplication::desktop() is always return qpe's default desktop
widget, not the real current widget which shown on screen. I think it
must be something wrong I configure the qpe env. But I can't find that.
The documents about qpe env is too less. My version is
Qtopia-phone-4.2.1.

I hope more help about it.

Thanks again!
