get QGraphicsView's border like frame pointer?

[satan_ljc]

i use QGraphicsScene and QGraphicsView to scale the child widget. now i want to move the child widget like the border frame, not just in the QGraphicsView.please help me how to do this?

my code is:



QASelectFrame::QASelectFrame(QWidget *parent) : QFrame(parent), ui(new Ui::QASelectFrame)
{
ui->setupUi(this);

m_scene = new QGraphicsScene;
m_scene->addWidget(this);
m_view = new QGraphicsView(m_scene);
//m_view->setFrameShape(QFrame::NoFrame);
m_view->setStyleSheet("border: 0px");

m_view->setWindowFlags(Qt::Window | Qt::FramelessWindowHint);
m_view->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOf f);
m_view->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff) ;
m_view->setContentsMargins(QMargins());

// title area
setTitleText(tr("Selector"));
}
