drawStaticText给出了错误

Question

我试图画静态文本，但得到错误，你能解释我做错了什么，为什么NoneType？

这里是代码：

sT = QtGui.QStaticText() 
text = 'text' 
painter.drawStaticText(QtCore.QPoint(40, 50), sT.setText(text)) 

和错误：

painter.drawStaticText(QtCore.QPoint(40, 50), staticT.setText(text)) 
TypeError: arguments did not match any overloaded call: 
QPainter.drawStaticText(QPointF, QStaticText): argument 2 has unexpected type 'NoneType' 
QPainter.drawStaticText(QPoint, QStaticText): argument 2 has unexpected type 'NoneType' 
QPainter.drawStaticText(int, int, QStaticText): argument 1 has unexpected type 'QPoint' 

谢谢。

Answer 1

我认为你有两个步骤

sT.setText(text) 
painter.drawStaticText(QtCore.QPoint(40, 50), sT) 

因为sT.setText(text)回报None，不QStaticText对象做。
