AttributeError: ‘MouseEvent‘ object has no attribute ‘GetPositionTuple‘问题解决

最近在学wxpython的绘画程序，遇到以下问题：

AttributeError: 'MouseEvent' object has no attribute 'GetPositionTuple'

网上搜了一下答案：

wxpython 4 不支持wx.MouseEvent.GetPositionTuple()
所以在获取鼠标位置时，如果要变成元组，就需要写成：
tuple(wx.MouseEvent.GetPosition())

所以绘画程序的第一个代码，需要改成一下：


self.pos = event.GetPositionTuple()
改成：
self.pos = tuple(event.GetPosition())newPos = event.GetPositionTuple()
改成：
newPos = tuple(event.GetPosition())

效果：
