如何点亮小部件的整个行？

Question

我有一个按钮列表，每个按钮对应于包含标签和lineEdit的网格布局中的一行。当我按下这些按钮之一时，我希望相应的行亮起。如何实现行的“点亮”？

类似这样的东西：

以下代码显示了我正在谈论的布局。

import sys
from PySide import QtGui
from PySide import QtCore
from PySide.QtGui import *
from PySide.QtCore import *

class MainWindow(QDialog):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.createLayout()
        self.setLayout(self.mainLayout)
        self.show()

    def createLayout(self):
        self.mainLayout = QVBoxLayout()
        self.button1 = QPushButton("Button1")
        self.button2 = QPushButton("Button2")
        self.button3 = QPushButton("Button3")

        #self.button1.clicked.connect(self.onButton1Press)
        #self.button2.clicked.connect(self.onButton2Press)
        #self.button3.clicked.connect(self.onButton3Press)

        self.HLay = QHBoxLayout()
        self.HLay.addWidget(self.button1)   
        self.HLay.addWidget(self.button2)   
        self.HLay.addWidget(self.button3)

        self.mainLayout.addLayout(self.HLay)    

        self.gridLay = QGridLayout()

        label1 = QLabel("Label1")
        line1 = QLineEdit()
        self.gridLay.addWidget(label1,0,0)
        self.gridLay.addWidget(line1,0,1)

        label2 = QLabel("Label2")
        line2 = QLineEdit()
        self.gridLay.addWidget(label2,1,0)
        self.gridLay.addWidget(line2,1,1)

        label3 = QLabel("Label3")
        line3 = QLineEdit()
        self.gridLay.addWidget(label3,2,0)
        self.gridLay.addWidget(line3,2,1)

        self.mainLayout.addLayout(self.gridLay)

    #def onButton1Press(self):
        #Highlight row in self.gridLay that contains label1 and line1

    #def onButton2Press(self):
        #Highlight row in self.gridLay that contains label2 and line2

    #def onButton3Press(self):
        #Highlight row in self.gridLay that contains label3 and line3



if __name__ == '__main__':
    app = QApplication(sys.argv)
    mainWin = MainWindow()
    ret = app.exec_()
    sys.exit( ret )

查看从QGraphicsEffect派生的类。可以使用QWidget :: setGraphicsEffect方法将图形效果应用于窗口小部件，您可以根据需要编写自己的效果。
