Question

meetis是我的src，

class CodeEditor(QPlainTextEdit, QLineEdit):
def __init__(self, parent=None):
    QPlainTextEdit.__init__(self, parent)
    QLineEdit.__init__(self, parent)
    self.lineNumberArea = LineNumberArea(self)
    self.blockCountChanged.connect(self.updateLineNumberAreaWidth)
    self.updateRequest.connect(self.updateLineNumberArea)
    self.cursorPositionChanged.connect(self.highlightCurrentLine)
    self.returnPressed.connect(self.IndentCall)
    self.updateLineNumberAreaWidth(0)


@pyqtSlot(str, QPlainTextEdit)
def IndentCall(self):
    if self.ui.textEdit.toPlainText().endswith(':\n'):
        self.ui.textEdit.insertPlainText('    ')

我得到的错误是，

File "D:\Python-Projects\CodeEditor\codeeditor.py", line 26, in __init__
self.returnPressed.connect(self.IndentCall)
TypeError: decorated slot has no signature compatible with returnPressed()

我不想创建一个事件处理程序，我想要的只是简单地将一个函数继承到另一个Widget中。如果可能的话，同事程序员请帮我解决这个错误。

!!在此先感谢!!
