Question

我是wxPython的新手，我使用以下教程创建了几个TextCtrl字段和内容。 http://sebsauvage.net/python/gui/#import

一切正常，除了我不能使用Tab按钮在字段之间切换，这非常烦人。我如何修改该教程中的示例（添加了一些TextCtrl），以便我可以使用tab在字段之间切换？

如果你不想看这个教程，它的基础是使用GridBagSizer将一堆TextCtrl放在它上面。

在网上搜索我发现的所有内容都是“创建一个面板”，但是我试过了，因为我对wxPython很新，所以它没有用，我找不到关于如何做到这一点的全面教程（如果可能的话）我想只坚持一个框架...）

谢谢！

Answer 1

您需要向框架添加wx.Panel，然后将面板对象作为所有其他窗口小部件的父对象。 wx.Panel添加了Tab键功能，使框架在所有平台上都看起来正确（大多数是正确的颜色）。如果您没有面板，则标签不起作用。

请参阅此主题，其中wxPython的创建者Robin Dunn说同样的话：https://groups.google.com/forum/?fromgroups=#!topic/wxpython-users/gF8r_HwnOEU

这是我之前制作的东西，它不是很好，但我可以假设你可以随意添加

import os
import wx

class tab(wx.Panel):
    def __init__(self, parent, newid=0, name="New Tab", file=None, aNewTab=False):
        wx.Panel.__init__(self, parent)
        self.control = wx.TextCtrl(self, style=wx.TE_MULTILINE)
        sizer = wx.BoxSizer()
        sizer.Add(self.control, -1, wx.EXPAND, newid)
        self.SetSizer(sizer)
        if file != None:
            self.control.write(file)
        else:
            pass

        self.buttons = []

        filemenu = wx.Menu()
        helpmenu = wx.Menu()

        menuSave = filemenu.Append(wx.ID_SAVE, "&Save", "Save the current file")
        menuSaveAs = filemenu.Append(wx.ID_SAVEAS, "&Save As", "Save the current file as")
        menuExit = filemenu.Append(wx.ID_EXIT, "E&xit", "Terminate the program")
