AttributeError:'QTextEdit'对象没有属性'text'

有时我需要用递增的数字复制代码的多个副本。 在我正在编写的表单中，我需要创建多达12个复选框，每个复选框都需要以下代码：

    self.checkBox1 = QtGui.QCheckBox()
    self.checkBox1.setGeometry(QtCore.QRect(20, 20, 70, 17))
    self.checkBox1.setObjectName(_fromUtf8("checkBox1"))

下面的脚本使我能够避免手动更改每个复选框的数字的枯燥任务。 我只是将上面的3行复制到windows剪贴板中，然后。。。 我在表单的第一个字段中插入复选框，在第二个字段中插入1，在第三个字段中插入12。 当我点击ok按钮时，3行的12个按顺序编号的副本出现在表单的第4个字段中。 我希望这能给其他人提供一些帮助。 马克

这是我的密码：

为QTextEdit调用该属性

与具有文本属性的单行QLineEdit相反，该属性被称为QTextEdit
