所以我有 2 个 QCheckBoxes 列表，它们驱动彼此的状态变化。每个列表驻留在一个选项卡中，该选项卡属于一组选项卡，属于一个主选项卡。当我生成复选框时，我一次生成一个选项卡，每个选项卡都有一个唯一的名称。我想知道我是否可以选中列表 1 中的特定复选框并在列表 2 中更改特定复选框的状态？

前任。结构

mainTab1 > tab 1 > list 1 checkBox 1-9
         > tab 2 > list 1 checkBox 1-4
         > tab 3 > list 1 checkBox 1-6

mainTab2 > tab 1 > list 2 checkBox 1-3
         > tab 2 > list 2 checkBox 1-11
         > tab 3 > list 2 checkBox 1-8

使用这种结构，如果我检查 mainTab1>tab2>list1checkBox3，我希望 mainTab2>tab1>list2checkBox1 检查该更改，我应该如何连接我的信号？

这是实际生成选项卡和复选框的代码

    global clusterNames
    global parseByPass
    totalPasses = parseByPass.keys()
    totalPasses.sort()
    cNames = reversed(clusterNames)
    assetCBList, assetNameList, assetPassList, assetROList = [],[],[],[]
    passCBList, passNameList, passPassList, passROList = [],[],[],[]

同步两个复选框非常简单。您将stateChanged信号从一个连接到另一个setCheckState方法，反之亦然：

 checkbox1.stateChanged.connect(checkbox2.setCheckState)
 checkbox2.stateChanged.connect(checkbox1.setCheckState)

现在您需要做的就是将您的复选框组织在一个合适的容器中，然后根据您的需要连接信号。由于您有唯一objectName的 s，a dictwith objectNamefor key 和相应的QCheckBox实例作为 value 似乎足够好。然后，您可以获得同步对列表。循环它们并连接信号。

如果我正确理解您的代码，它应该是这样的（剪掉不相关的位以强调逻辑）：

# some code snipped here
# ...
self.checkBoxes = {}
# this is just an example
# your real syncPairs should include real names and full list of pairs of course
self.syncPairs = [('list2checkBox1', 'list1checkBox3')] 

for index, item in enumerate(cNames):
    # more code snipped here

    self.allCB = QtGui.QCheckBox()   # I'm not sure about 'self.' part
                                        # You are discarding the old one in the next iteration
                                        # So this will just store the last one in the iteration
                                        # Besides we are going to keep references to all in `self.checkBoxes`
    self.allCB.setObjectName("%sAllCB" % item)

    # here add it to the dict
    self.checkBoxes["%sAllCB" % item] = self.allCB

    # code snipped here

    # btw, you should add these ones to the layout _here_, not in the inner loop. So:
    self.tabLayout.addWidget(self.allCB,0,0)
    self.tabLayout.addWidget(self.allNameLabel,0,1)
    self.tabLayout.addWidget(self.allPassLabel,0,2)
    self.tabLayout.addWidget(self.allRenderOpt,0,3)

    #Create modullar widgets based on parsed info
    for index, stat in enumerate(QParsed[item][1]):
        # code snipped here

        #Add modularly generated widgets with parsed info
        self.assetCB = QtGui.QCheckBox()      # Again, same issue with 'self.'
        self.assetCB.setObjectName(assetCB)

        # add it to the dict
        self.checkBoxes[assetCB] = self.assetCB

        # rest of the code snipped

# after the setup done, we can connect the signals that will keep sync status:
for cb1, cb2 in self.syncPairs:
     self.checkBoxes[cb1].stateChanged.connect(self.checkBoxes[cb2].setCheckState)
     self.checkBoxes[cb2].stateChanged.connect(self.checkBoxes[cb1].setCheckState)

两个同步复选框的简单演示：

import sys
from PyQt4 import QtGui

class Dialog(QtGui.QDialog):
    def __init__(self, parent=None):
        super(Dialog, self).__init__(parent)

        layout = QtGui.QVBoxLayout()
        self.setLayout(layout)

        self.cb1 = QtGui.QCheckBox('checkbox 1')
        self.cb2 = QtGui.QCheckBox('checkbox 2')

        #self.cb1.stateChanged.connect(self.cb2.setCheckState)
        #self.cb2.stateChanged.connect(self.cb1.setCheckState)

        # alternatively
        self.cb1.toggled.connect(self.cb2.setChecked)
        self.cb2.toggled.connect(self.cb1.setChecked)

        layout.addWidget(self.cb1)
        layout.addWidget(self.cb2)

        self.setWindowTitle('Synced checkboxes')


if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)

    main = Dialog()
    main.show()

    sys.exit(app.exec_())
