选中复选框后调用功能

我希望更改行编辑后会调用另一个函数,并且该函数中有一个Qt.Checked的if-else。当我编辑行编辑,然后选中复选框时,行编辑中的文本将写入变量。但是,当我再次更改行编辑时,即使选中了该复选框,它也仅在更改功能中运行else。我不明白为什么。

复选框:

self.filenamecheck.stateChanged.connect(self.changeFileName)

LineEdit:

self.nameLine.textEdited.connect(self.onChangeNameLine)

功能:

def onChangeNameLine(self,state):
    self.changeFileName(self)
    print("Filename changed")

def changeFileName(self, state):
    name = self.nameLine.text()
    print("Called change function")
    if state == Qt.Checked:
        self.filenameLine.setText(name)
        print("called change if")
    else:
        self.filenameLine.setText('')
        print("called change else")

谢谢您的帮助!

def onChangeNameLine(self):
    self.changeFileName()
    print("Filename changed")

def changeFileName(self):
    name = self.nameLine.text()
    print("Called change function")
    if self.filenamecheck.isChecked():
        self.filenameLine.setText(name)
        print("called change if")
    else:
        self.filenameLine.setText('')
        print("called change else")
