drawStaticText给出错误

Question

我试图绘制静态文本但得到错误，你能解释我做错了什么，为什么是NoneType？

这是代码：

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

我认为你必须分两步完成

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

因为sT.setText(text)返回None，而不是QStaticText对象。
