如何在wxPython的框架中使字段之间的选项卡工作

Question

我是wxPython的新手，我使用下面的教程创建了几个TextCtrl字段和东西。进口http://sebsauvage.net/python/gui/

一切都工作，除了我不能使用Tab按钮切换字段，这是非常烦人的。我如何修改该教程中的示例(添加了更多的TextCtrl)，以便我可以使用选项卡在字段之间切换?

如果你不想看教程，它基本上是一个框架，使用GridBagSizer在它上面放了一堆TextCtrl。

在网上搜索时，我发现的是"创建一个面板"，但我试过了，因为我是wxPython的新手，它不起作用，我找不到一个关于如何做到这一点的完整教程(如果可能的话，我想坚持只有一个框架…)

谢谢!

Answer 1

您需要添加一个wx。面板到框架，然后将面板对象作为所有其他小部件的父对象。的天气。面板增加了选项卡功能，使框架在所有平台上看起来都是正确的(大多数是正确的颜色)。如果你没有面板，那么选项卡将不起作用。

看看这个线程Robin Dunn, wxPython的创建者，说了同样的话:https://groups.google.com/forum/?fromgroups=#!主题/wxpython-users gF8r_HwnOEU

这是我之前做的一些东西，它不是很好但我可以假设你可以根据需要添加

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

    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, title=title, size=(1000,900))

        self.buttons = []
        filemenu = wx.Menu()
        helpmenu = wx.Menu()
        menuOpen = filemenu.Append(wx.ID_OPEN, "&Open", "Open a file to edit")
        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")
