QComboBox自绘 [复制链接]

在Qt4中怎么样才能去掉QComboBox右边的下拉按钮（QStyle::SC_ComboBoxArrow）？？？

    QString l_sStyleSheet = "QComboBox::drop-down {\
                            border-image: url(res/ST_icon_pull-down_r.png) 5;\
                            border-width: 5;\
                            }\
                            QComboBox{\
                            border-image: url(res/ST_icon_pull-down_base.png) 5;\
                            border-width: 5;\
                            }\
                            ";


    QComboBox* temp = new QComboBox(this);
    temp->setStyleSheet(l_sStyleSheet);
    temp->addItem("test1");
    temp->addItem("test2");
    temp->addItem("test3");
    temp->setGeometry(0, 0, 480, 100);

    QStyle* tempStyle = temp->style();

我弄了半天才弄好的。换张图片通过stylesheet放上去就好。
