Question

我这里有一个非常不稳定的问题。运行时，菜单栏随机出现。我已经多次尝试在整个程序中重复使用self.SetMenuBar（self.menuBarr），但它似乎不会影响成功率。有没有人知道任何类型的触发器的位置，它指示菜单栏是否已经显示，以便我可以在需要时自动重新加载它？

或者，我已经看过一些类似（但不同）的帖子here和here，所以如果它与所提到的错误相关，那么有人知道我如何调整黑客（在第一个链接）为一个简单的菜单栏工作？

在初始wx.Frame构造函数中，对menu（）方法的调用已从创建序列的开头移动到结尾也可能是有用的信息，但它也没有影响到的可靠性。菜单栏项目。没有例外。

提前感谢您提供的任何帮助！

更新现在这开始变得非常奇怪。我通过使用管理员权限执行程序解决了这个问题。我的任何脚本都不会删除shell命令，所以我完全不知道为什么会这样。

菜单是否出现在任务栏区域，就像Mac一样？我认为在较新的Ubuntu版本中有一些禁用菜单的设置。我不记得它现在叫什么，但我认为你必须安装一个插件，否则它会被禁用，具体取决于主题。另请参阅http://wxpython-users.1045709.n5.nabble.com/help-no-show-menubar-in-ubuntu-td3292261.html

你没有提到你正在使用哪种wxPython。如果它不是2.8.12，请尝试升级到它并查看它是否已修复：https://groups.google.com/forum/?fromgroups#!topic/wxpython-users/7tx9i1TpfZc

菜单栏出现50％的时间，wxPython，Ubuntu 11.10，Python 2.7，wxPython 2.8 GTK2
