QT/WebKit::How to use qvfb?

qvfb是Qt Virtual FrameBuffer的缩写，是QT在X11下的一个framebuffer仿真器，qte的应用程序就可以显示在qvfb上，qvfb提供了键盘和鼠标支持，这样开发人员就不需要将qte应用程序移到目标板上去运行和调试，大大地提升了工作效率。

Build QT tool qvfb
    cd ~/Workshop
    tar xvf qt-everywhere-opensource-src-4.7.1.tar.gz
    mv qt-everywhere-opensource-src-4.7.1 qt-x11
    ./configure -debug -qvfb -confirm-license -nomake docs -developer-build -opensource -prefix /usr/local/Trolltech/Qt-X11
    make
    cd tools/qvfb
    make
    cd ../../
    sudo make install

Build QTE for qvfb
    cd ~/Workshop
    tar xvf qt-everywhere-opensource-src-4.7.1.tar.gz
    mv qt-everywhere-opensource-src-4.7.1 qt-embedded
    ./configure -debug -qvfb -qt-gfx-qvfb -qt-kbd-qvfb -qt-mouse-qvfb -embedded -confirm-license -nomake docs -developer-build -opensource -prefix /usr/local/Trolltech/Qt-embedded
    make
    sudo make install

Have a test
    用QT自带的例子测试：
    cd ~/Workshop/qt-x11/bin
    ./qvfb &
    cd ~/Workshop/qt-embedded/demos/gradients
    ./gradients -qws -qvfb
   
   
    自己写个简单例子测试：
    /*test.cpp*/
    #include
    #include
    #include

    int main(int argc, char * argv[])
    {
        QApplication app(argc,argv);
        QWidget* pWidget  = new QWidget;
        QLabel label(pWidget);
        label.setText(QObject::tr("One World,One Dream!"));
        pWidget->show();
        return app.exec();
    }
   
    /usr/local/Trolltech/bin/qmake -project
    /usr/local/Trolltech/bin/qmake
    make
    ./test -qws -qvfb
