平面菜单中是否有与键"2"(键码= 50)关联的快捷方式？

Question

我正在尝试开发显示FlatMenu、工具栏和以下面板的应用程序。在工具栏上我放了一个文本控件。当我试图输入键"2"时，它没有被键入。我试着调试代码，它在日志中打印密钥代码，但在textctrl中它没有被键入。除了‘2’，我可以输入所有其他键。

您发布的代码在我的系统上根本无法正常工作，这是因为您试图在没有任何子级的面板上使用sizer。我对代码进行了一些修改，使其看起来更好（Windows 7，wxPython 2.9.4），然后将问题追溯到如何设置FlatMenu。你知道有一个FlatMenu.py演示吗？

https://github.com/crankycoder/wxPython-2.9.2.4/blob/master/wxPython/demo/agw/FlatMenu.py

从中得到一些想法，我只在FlatMenu中添加了几个条目，它适用于数字2，所以我假设你使用了一个特殊的ID（通常建议使用wx.ID_ANY，而不是硬编码的ID，因为有些ID有特殊效果）。请检查注释掉的代码，看看你将如何继续修改它以使其工作。

另一个可能最终导致问题的大问题是，你过度使用了"file"one_answers"type"等保留字。
