在wxPython中，如何使字段之间的制表符起作用

Question

我对wxPython非常陌生，我使用下面的教程创建了几个textcrl字段和其他东西。 http://sebsauvage.net/python/gui/#import

除了我不能用Tab键在字段之间切换之外，一切都正常，这很烦人。如何修改教程中的示例（添加了更多textcrl），以便可以使用tab在字段之间切换？在

如果你不想看这个教程，它的基本框架是一个用GridBagSizer放在上面的文本控制框。在

当我在网上搜索时，我只找到了“创建一个面板”，但是我试过了，因为我对wxPython很陌生，所以没有找到一个关于如何做到这一点的完整教程（如果可能的话，我只想用一个框架…）

谢谢！在

这是我以前做的一些东西，它不是很好，但我可以假设你可以添加到你想要的

import os
import wx

你需要添加一个wx.面板然后将panel对象作为所有其他小部件的父对象。这个wx.面板添加了标签功能，使框架在所有平台上看起来都是正确的（主要是正确的颜色）。如果你没有面板，那么标签就不起作用了。在

看看这个帖子，wxPython的创建者robindunn说了同样的话：https://groups.google.com/forum/?fromgroups=#!topic/wxpython-users/gF8r_HwnOEU
