Question

我正在使用pyqt和python进行一个项目，我对这两个项目都很陌生。我在Qt设计器中进行了窗口设计，现在我正在实现代码。

如何制作循环以检查我拥有的多个复选框中的哪一个？

class MainUi(QtGui.QMainWindow):


def __init__(self):             
    super(MainUi, self).__init__()
    self.ui = Ui.Ui_MainWindow()
    self.ui.setupUi(self)
    self.xmon = xmon2.MainUi()
    self.xmon.show()
    self.timer = XTimer(1)


    #Selection of generation to run
    self.connect(self.ui.checkBoxGen2, QtCore.SIGNAL("clicked()"), self.gen2Selected)
    self.connect(self.timer, QtCore.SIGNAL("tick"), self.onEventTick)
    self.connect(self.ui.checkBoxGen3, QtCore.SIGNAL("clicked()"), self.gen3Selected)

    #Select RS232 or CAN
    self.connect(self.ui.checkBoxCAN, QtCore.SIGNAL("clicked()"), self.canSelected)
    self.connect(self.ui.checkBoxRS232, QtCore.SIGNAL("clicked()"), self.rs232Selected)

    #Select single test or continuous test
    self.connect(self.ui.checkBoxConTest, QtCore.SIGNAL("clicked()"), self.conTestSelected)
    self.connect(self.ui.checkBoxSingTest, QtCore.SIGNAL("clicked()"), self.singTestSelected)

    #The RUN button is pressed
    self.connect(self.ui.pushButtonRun, QtCore.SIGNAL("clicked()"), self.runButtonPushed)

    self.connect(self.ui.pushButtonRunGen3, QtCore.SIGNAL("clicked()"), self.runButtonGen3Pressed)

    self.timer.start()

    if self.ui.checkBoxUnit1Gen2.ischecked():
        Unit1 = create_unit(self, 1 , self.ui.lineEditComUnit1Gen2.text()  

    if self.ui.checkBoxUnit2Gen2.ischecked():
        Unit2 = create_unit(self, 2 , self.ui.lineEditComUnit2Gen2.text()  

    if self.ui.checkBoxUnit3Gen2.ischecked():
        Unit3 = create_unit(self, 3 , self.ui.lineEditComUnit3Gen2.text()  

    if self.ui.checkBoxUnit4Gen2.ischecked():
        Unit4 = create_unit(self, 4 , self.ui.lineEditComUnit4Gen2.text()

所以上面是我想要改变的代码的一部分。所以我想删除if语句并用循环替换它们。对于每个选中的复选框，应使用复选框的编号创建新单元。现在它只有四个盒子，但会有更多。

#PyQt, check multiple check boxes
#Please follow any one of the below line. I hope you can achieve your result. 

#1. Find the all QCheckBox in UI.
#OR
#2. Put all QCheckBox to one QGroupBox(QCheckBox become child of this QGroupBox), then find the QCheckBox Childern of QGroupBox. 
#OR
#3. Put all QCheckBox to any layouts like QHBoxLayout, QVBoxLayout, QGridLayout (QCheckBox become child of particular Layout), then find the QCheckBox Childern of particular Layout.

#If your are not expecting this answer, sorry.
#Thanks, Subin

PyQt，勾选多个复选框
