想用wxpython实现绘图功能，但是提示获取不到鼠标的位置数组，但是GetPosition仍然是可以调用的，这种情况该怎么解决呢？

[陈年椰子]

wx.GetMousePosition() 这个吗？

引用 1 楼 陈年椰子 的回复:

是想要获得鼠标移动过程中经过的点坐标的数组，用的getPositionTuple()，但是报错提示MouseEvent没有这个属性

[qq_21456601]

1. 两个位置event.GetPositionTuple()更改event.GetPosition()
2. 删掉下面两条
coords = self.pos + newPos
self.curLine.append(coords)
3.dc.DrawLine(*coords) 更换dc.DrawLine(self.pos,newPos)

[心滩]

改成：wx.GetPosition()即可

[心滩]

改成：wx.GetPosition()即可
67行：coords = self.pos + newPos 改成：coords = (self.pos, newPos)即可

[sunpanqing]

改成：event.GetPosition()即可
67行：coords = self.pos + newPos 改成：coords = (self.pos, newPos)即可
