[Qt-interest] How can I translate a widget in different process?

[Kermit Mei]

Dear all,
    I have many processes run on qpe, Now I need to translate process
A's widget to process B, so that in B can paint A's widget.
    I want to use QApplication::desktop() to do that. But
QApplication::desktop() always return the same QPE backgroud.

    How can I implement it?

Thanks
