wxpython - Wx.choice 在 ubuntu 中不工作

Question

我只会说西类牙语，我会尽量用我糟糕的英语写，抱歉。

我正在学习 wx.Python，我在 Windows XP 中编写了一个小示例并运行完美，但相同的代码在 ubuntu Jaunty 中运行不佳。

wx.Choice的字体看起来很模糊，选项几乎看不到，当你选择一个时，Label总是空的。

print self.choice1.Label 在 ubuntu 中总是打印 EMPTY，在 Windows 中打印 suma、resta 或 mul，wx.choice 的选项之一，如何预期。

使用self.choice1.Label是错误的；在整个代码中用 self.choice1.StringSelection 替换它，您的代码就可以工作了!
