drawStaticText給出了錯誤

Question

我試圖畫靜態文本，但得到錯誤，你能解釋我做錯了什麼，爲什麼NoneType？

這裏是代碼：

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

和錯誤：

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' 

謝謝。

Answer 1

我認爲你有兩個步驟

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

因爲sT.setText(text)回報None，不QStaticText對象做。
