带wx问题的热心Mayavi嵌入

Question

一开始我的运行系统：

我使用存储库中的windows8pro和Mayavi 4.3以及python2.7.4中的wxpython2.9.4.0，但EPD包中的Mayavi 4.2.1也有同样的问题。。。在

当我试图将mayavi嵌入笔记本面板时，UI出现了一些问题。即使在mayavi的演示文件中，我也得到了mayavi生成的外部帧的相同奇怪行为。在

因此，使用“设置”按钮a，将打开“设置”窗口。同时，场景会对我使用设置更改的参数做出反应。但单击“确定”或“香奈儿”后，窗口不会关闭。python会返回几个错误消息。当我使用管道时mlab.show_管道（）命令。在

此行为也可以在sample from the enthought web page上找到。在

在这里，您可以看到我在第三个示例的设置框中单击“确定”后出现的错误消息：

提前谢谢

Answer 1

至少可以通过与此PR相关联的更改来解决此特殊异常：https://github.com/enthought/traitsui/pull/108。我还不知道Mayavi和栈的其他部分，但这种改变至少会让traitsui与wxpython2.9一起工作。在

Answer 2

Mayvi与wx 2.9不兼容。在

请使用enpkg恢复为随EPD提供的wx 2.8。在
