python之PyQt4 图像作为背景

我正在使用设计师的下面代码，我试图让 Qwidget 有一个图像作为背景，然后让列表小部件和文本编辑小部件透明。

我遇到的主要问题是，当我使用“表单”的样式表将图像作为背景时，它也会作为列表小部件和文本编辑小部件的背景。我如何让那些保留自己的样式表。

from PyQt4 import QtCore, QtGui 
 
try: 
    _fromUtf8 = QtCore.QString.fromUtf8 
except AttributeError: 
    def _fromUtf8(s): 
        return s 
 
try: 
    _encoding = QtGui.QApplication.UnicodeUTF8 
    def _translate(context, text, disambig): 
        return QtGui.QApplication.translate(context, text, disambig, _encoding) 
except AttributeError: 
    def _translate(context, text, disambig): 
        return QtGui.QApplication.translate(context, text, disambig) 
 
class Ui_Form(object): 
    def setupUi(self, Form): 
        Form.setObjectName(_fromUtf8("Form")) 
        Form.setEnabled(True) 
        Form.resize(854, 667) 
        Form.setAutoFillBackground(False) 
        Form.setStyleSheet("background-image: url(test.jpg);") 
        self.textEdit = QtGui.QTextEdit(Form) 
        self.textEdit.setGeometry(QtCore.QRect(20, 400, 821, 251)) 
        self.textEdit.setStyleSheet(_fromUtf8("background-color: rgba(255, 255, 255, 102);")) 
        self.textEdit.setObjectName(_fromUtf8("textEdit")) 
        self.listWidget = QtGui.QListWidget(Form) 
        self.listWidget.setGeometry(QtCore.QRect(360, 10, 471, 371)) 
        self.listWidget.setAutoFillBackground(True) 
        self.listWidget.setStyleSheet(_fromUtf8("background-color: rgba(255, 255, 255, 102);")) 
        self.listWidget.setObjectName(_fromUtf8("listWidget")) 
        item = QtGui.QListWidgetItem() 
        item.setCheckState(QtCore.Qt.Checked) 
        self.listWidget.addItem(item) 
        item = QtGui.QListWidgetItem() 
        item.setCheckState(QtCore.Qt.Checked) 
        self.listWidget.addItem(item) 
 
        self.retranslateUi(Form) 
        QtCore.QMetaObject.connectSlotsByName(Form) 
 
    def retranslateUi(self, Form): 
        Form.setWindowTitle(_translate("Form", "Form", None)) 
        __sortingEnabled = self.listWidget.isSortingEnabled() 
        self.listWidget.setSortingEnabled(False) 
        item = self.listWidget.item(0) 
        item.setText(_translate("Form", "blah blh sdfsaasdfdsfasf", None)) 
        item = self.listWidget.item(1) 
        item.setText(_translate("Form", "test", None)) 
        self.listWidget.setSortingEnabled(__sortingEnabled) 
 
if __name__ == "__main__": 
    import sys 
    app = QtGui.QApplication(sys.argv) 
    Form = QtGui.QWidget() 
    ui = Ui_Form() 
    ui.setupUi(Form) 
    Form.show() 
    sys.exit(app.exec_()) 

谢谢

请您参考如下方法:

这对我有用:

    self.text_field = QtGui.QPlainTextEdit(self) 
    self.text_field.setMinimumSize (480,150) 
    self.text_field.setStyleSheet("background-image: url(FILENAME); background-attachment: fixed")
