python - pyqt4 : AttributeError: 'QPlainTextEdit' object has no attribute 'text'

Question

我知道我也有类似的问题，但是我尝试了这些解决方案，但它们不起作用。

我有文本字段:

self.tMail = QtGui.QPlainTextEdit(self.centralwidget)
self.tMail.setGeometry(QtCore.QRect(50, 270, 451, 75))
self.tMail.setAccessibleName(_fromUtf8(""))
self.tMail.setInputMethodHints(QtCore.Qt.ImhNone)
self.tMail.setPlainText(_fromUtf8(""))
self.tMail.setOverwriteMode(False)
self.tMail.setObjectName(_fromUtf8("tMail"))

我想通过以下方式将它们添加到变量字符串中:

def handleButton(self):
    timeString = self.tCzas.text()
    mailString = self.tMail.text()
    IDString = self.tID.text()
    teamString = self.tTeam.text()
    print(timeString)
    print(mailString)
    print(IDString)
    print(teamString)`

我也试过了:
mailString = self.tMail.plainText()
我总是得到一个错误:AttributeError: 'QPlainTextEdit' object has no attribute '...'
为什么？

QPlainTextEdit没有text()函数。尝试使用toPlainText()函数:

def handleButton(self):
    timeString = self.tCzas.toPlainText()
    mailString = self.tMail.toPlainText()
    IDString = self.tID.toPlainText()
    teamString = self.tTeam.toPlainText()
    print(timeString)
    print(mailString)
    print(IDString)
    print(teamString)
