从pyqt4python中的另一个radiobutton禁用和启用radiobutton

Question

我有3个radiobutton组，形式为Yes或No。如果第一个radiobutton为“No”，我想禁用最后2个radiobutton组，并在第一个radiobutton为“Yes”时启用它们。我可以在默认情况下启用或禁用，但是在第一组中切换是/否不会改变第二组和第三组的结果。在

以下是我的代码摘要：

self.yes_radioButtonGroup1 = QtGui.QRadioButton(self.centralwidget)      
self.yes_radioButtonGroup1.setObjectName(_fromUtf8("yes_radioButtonGroup1"))
self.no_radioButtonGroup1 = QtGui.QRadioButton(self.centralwidget)
self.no_radioButtonGroup1.setObjectName(_fromUtf8("no_radioButtonGroup1"))
self.radioButtonGroup1= QtGui.QButtonGroup(MainWindow)   
self.radioButtonGroup1.setObjectName(_fromUtf8("radioButtonGroup1"))
self.radioButtonGroup1.addButton(self.yes_radioButtonGroup1)
self.radioButtonGroup1.addButton(self.no_radioButtonGroup1)

self.yes_radioButtonGroup2 = QtGui.QRadioButton(self.centralwidget)      
self.yes_radioButtonGroup2.setObjectName(_fromUtf8("yes_radioButtonGroup2"))
self.no_radioButtonGroup2 = QtGui.QRadioButton(self.centralwidget)
self.no_radioButtonGroup2.setObjectName(_fromUtf8("no_radioButtonGroup2"))
self.radioButtonGroup2= QtGui.QButtonGroup(MainWindow)   
self.radioButtonGroup2.setObjectName(_fromUtf8("radioButtonGroup2"))
self.radioButtonGroup2.addButton(self.yes_radioButtonGroup1)
self.radioButtonGroup2.addButton(self.no_radioButtonGroup1)

self.yes_radioButtonGroup3 = QtGui.QRadioButton(self.centralwidget)      
self.yes_radioButtonGroup3.setObjectName(_fromUtf8("yes_radioButtonGroup3"))
self.no_radioButtonGroup3 = QtGui.QRadioButton(self.centralwidget)
self.no_radioButtonGroup3.setObjectName(_fromUtf8("no_radioButtonGroup3"))
self.radioButtonGroup3= QtGui.QButtonGroup(MainWindow)   
self.radioButtonGroup3.setObjectName(_fromUtf8("radioButtonGroup3"))
self.radioButtonGroup3.addButton(self.yes_radioButtonGroup3)
self.radioButtonGroup3.addButton(self.no_radioButtonGroup3)


if self.yes_radioButtonGroup1.isChecked() == True:
        self.yes_radioButtonGroup2.setEnabled(True)
        self.no_radioButtonGroup2.setEnabled(True)
        self.yes_radioButtonGroup3.setEnabled(True)
        self.no_radioButtonGroup3.setEnabled(True)

elif self.no_radioButtonGroup1.isChecked() == True:
        self.yes_radioButtonGroup2.setEnabled(False)
        self.no_radioButtonGroup2.setEnabled(False)
        self.yes_radioButtonGroup3.setEnabled(False)
        self.no_radioButtonGroup3.setEnabled(False)

我想知道当第一个radiobutton的值发生变化时，是否有人知道如何动态地启用或禁用最后两个radiobutton组？在

由于按钮是独占的，足以监视其中一个按钮，因此适当的信号是toggled()，它在按钮是否被选中时发送信息。在

    self.yes_radioButtonGroup1 = QtGui.QRadioButton(self.centralwidget)      
    self.yes_radioButtonGroup1.setObjectName(_fromUtf8("yes_radioButtonGroup1"))
    self.no_radioButtonGroup1 = QtGui.QRadioButton(self.centralwidget)
    self.no_radioButtonGroup1.setObjectName(_fromUtf8("no_radioButtonGroup1"))
    self.radioButtonGroup1= QtGui.QButtonGroup(MainWindow)   
    self.radioButtonGroup1.setObjectName(_fromUtf8("radioButtonGroup1"))
    self.radioButtonGroup1.addButton(self.yes_radioButtonGroup1)
    self.radioButtonGroup1.addButton(self.no_radioButtonGroup1)

    self.yes_radioButtonGroup2 = QtGui.QRadioButton(self.centralwidget)      
    self.yes_radioButtonGroup2.setObjectName(_fromUtf8("yes_radioButtonGroup2"))
    self.no_radioButtonGroup2 = QtGui.QRadioButton(self.centralwidget)
    self.no_radioButtonGroup2.setObjectName(_fromUtf8("no_radioButtonGroup2"))
    self.radioButtonGroup2= QtGui.QButtonGroup(MainWindow)   
    self.radioButtonGroup2.setObjectName(_fromUtf8("radioButtonGroup2"))
    self.radioButtonGroup2.addButton(self.yes_radioButtonGroup1)
    self.radioButtonGroup2.addButton(self.no_radioButtonGroup1)

    self.yes_radioButtonGroup3 = QtGui.QRadioButton(self.centralwidget)      
    self.yes_radioButtonGroup3.setObjectName(_fromUtf8("yes_radioButtonGroup3"))
    self.no_radioButtonGroup3 = QtGui.QRadioButton(self.centralwidget)
    self.no_radioButtonGroup3.setObjectName(_fromUtf8("no_radioButtonGroup3"))
    self.radioButtonGroup3= QtGui.QButtonGroup(MainWindow)   
    self.radioButtonGroup3.setObjectName(_fromUtf8("radioButtonGroup3"))
    self.radioButtonGroup3.addButton(self.yes_radioButtonGroup3)
    self.radioButtonGroup3.addButton(self.no_radioButtonGroup3)

    self.yes_radioButtonGroup1.toggled(self.on_yes_checked)
    # set initial state
    self.on_yes_checked(self.yes_radioButtonGroup1.isChecked())

def on_yes_checked(self, checked):
    self.yes_radioButtonGroup2.setEnabled(checked)
    self.no_radioButtonGroup2.setEnabled(checked)
    self.yes_radioButtonGroup3.setEnabled(checked)
    self.no_radioButtonGroup3.setEnabled(checked)
