属性错误：'QTextEdit'对象没有'text'属性。

Question

有时我需要复制带有递增数字的代码。 在我编写的表单中，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"))

以下脚本使我能够避免手动更改每个复选框的数字的繁琐任务。 我只需将上面的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"checkBox"，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，12个顺序编号的3行副本出现在表单的第4个字段中。 我希望这对其他人有所帮助。 Marc

以下是我的代码:

QTextEdit控件的属性称为plainText。

（与只有文本属性的单行QLineEdit控件相反）
