Question

我有旧的wxPython 2.0代码：

region = wx.RegionFromPoints([(0, 0), (w, 0), (w, h), (0, h)])
box = wx.RegionFromPoints([(100, 100), (500, 100), (500, 500), (100, 500)])
region.SubtractRegion(box)

现在在wxPython 3.0中它看起来像这样：

region = wx.Region([(0, 0), (w, 0), (w, h), (0, h)])
box = wx.Region([(100, 100), (500, 100), (500, 500), (100, 500)])
region.SubtractRegion(box)

Traceback看起来像这样：

Traceback (most recent call last):
  File "transparent.py", line 22, in OnPaint
    region.SubtractRegion(box)
AttributeError: 'Region' object has no attribute 'SubtractRegion'

检查Phoenix文档，它没有提及新wxPython 3.0中的“SubtractRegion”

有解决方法吗？

Answer 1

现在只有Subtract，因为不再需要重命名为SubtractRegion来支持重载。请参阅Subtract方法可用的重载文档：https://docs.wxpython.org/wx.Region.html#wx.Region.Subtract

另外https://docs.wxpython.org/MigrationGuide.html#overloaded-functions

如何在wxPython Phoenix中减去区域？
