如何获取PyQt中QGroupbox中存在的Qcheckbox的状态

在这里,用户可以根据需要选择复选框,然后按下确定按钮.按下确定按钮后,我应该能够获得用户选中的复选框列表.

我在循环中创建复选框,这是代码：

def createGroupBox(self,livename,shotlist):        

    groupBox = QtGui.QGroupBox("Live-"+livename)        
    grpLayout = QtGui.QVBoxLayout()
    i=0
    while  i != (len(shotlist)-2):
        qChkBx_shot = QtGui.QCheckBox("Shot-"+shotlist[i],self)
        qChkBx_shot.stateChanged.connect(lambda: self.groupcheckBoxToggled(livename,qChkBx_shot.text()))
        grpLayout.addWidget(qChkBx_shot,QtCore.Qt.AlignCenter)
        i +=1

    groupBox.setLayout(grpLayout)
    return groupBox

使用以下代码的GroupBox：

def InitUi(self,livelist,shotlist):
    scrolllayout = QtGui.QGridLayout()

    scrollwidget = QtGui.QWidget()
    scrollwidget.setLayout(scrolllayout)

    scroll = QtGui.QScrollArea()
    scroll.setWidgetResizable(True)  # Set to make the inner widget resize with scroll area
    scroll.setWidget(scrollwidget)

    i=0
    length = len(livelist)-2
    x,y=0,0 

    while x <=  math.ceil(length/4):
        for y in range(0,4):
            if (i < (length)):
                groupbox=self.createGroupBox(livelist[i],shotlist)
                self.groupboxes.append(groupbox)
                scrolllayout.addWidget(groupbox,x,y)
            y +=1
            i +=1
        x+=1

    self.Okbutton = QtGui.QPushButton('OK',self)
    self.Okbutton.clicked.connect(lambda: self.buttonPressed())
    self.Okbutton.setMaximumWidth(100)
    layout = QtGui.QVBoxLayout()
    layout.addWidget(scroll)

    layout.addWidget(self.Okbutton,QtCore.Qt.AlignRight)
    self.setLayout(layout)        
    self.setWindowTitle("Customized LiveShotLiveSwitching")
    self.resize(1200,500) 
    self.show()

在这里,我的查询是,我能够检索哪个组框被激活的值,我无法获得在该组框下检查的复选框列表.

任何人都可以帮我解决这个问题……
