这个错误表示你传递给函数的参数是float类型,而函数期望的参数类型是QLineF、QLine、int、QPoint或QPointF类型之一。你需要将参数转换为正确的类型,否则会出现类型错误。
例如,如果你想要使用drawLine函数绘制两个点之间的线段,你可以将参数转换为QPointF类型:
```python
from PyQt5.QtCore import QPointF, Qt
# 创建两个点
p1 = QPointF(0.0, 0.0)
p2 = QPointF(100.0, 100.0)
# 绘制线段
painter.drawLine(p1, p2)
```
或者你也可以使用QLineF类型的参数,例如:
```python
from PyQt5.QtCore import QLineF, Qt
# 创建两个点
p1 = QPointF(0.0, 0.0)
p2 = QPointF(100.0, 100.0)
# 创建线段
line = QLineF(p1, p2)
# 绘制线段
painter.drawLine(line)
```
请根据你的实际需求将参数转换为正确的类型,并确保传递给函数的参数类型与函数期望的参数类型相匹配。
