所以我有2个QCheckBoxes列表来驱动彼此的状态变化。每个列表都位于一个选项卡中，该选项卡属于一组选项卡，属于主选项卡。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查看列表1中的特定复选框，并在列表2中有一个特定复选框的状态更改？
实施例。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＆gt; tab2＆gt; list1checkBox3，我希望mainTab2＆gt; tab1＆gt; list2checkBox1检查该更改，我应该如何连接我的信号？
这是实际生成标签和复选框的代码

答案 0 :(得分：0)
同步两个复选框非常简单。您将stateChanged信号从一个信号连接到另一个信号的setCheckState信号，反之亦然：
checkbox1.stateChanged.connect(checkbox2.setCheckState)
checkbox2.stateChanged.connect(checkbox1.setCheckState)
现在您只需要在合适的容器中整理复选框，然后根据需要连接信号。由于您拥有唯一的objectName，因此对于密钥和相应的dict实例，objectName QCheckBox的值似乎已经足够了。然后你可以有一个同步对列表。环绕它们并连接信号。
如果我正确理解你的代码，这应该是它的样子（用不相关的位剪断以强调逻辑）：
# 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)
修改
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_())
