如何使字段在wxPython中的框架中工作

Question

我對wxPython非常新，我已經使用以下教程來創建幾個TextCtrl字段和東西。 http://sebsauvage.net/python/gui/#import

一切工作除了我不能切換字段之間使用Tab鍵非常討厭。我如何修改該教程中的示例（添加了更多的TextCtrl），以便我可以使用Tab在字段之間切換？

如果你不想看看教程，它的basicalyl框架與一堆TextCtrl放在它使用GridBagSizer。

在網上搜索時，我發現所有的東西都是「創建面板」，但我嘗試過，因爲我對wxPython非常陌生，它沒有工作，我無法找到一個徹底的教程如何做到這一點（如果可能的Id喜歡堅持只有一個框架...）

謝謝！

這裏的東西，我之前提出的，它是不是很好，但我可以假設你可以添加到它，只要你想

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 

class MainWindow(wx.Frame): 

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

     self.buttons = [] 

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

     menuOpen = filemenu.Append(wx.ID_OPEN, "&Open", "Open a file to edit")

你需要一個wx.Panel添加到幀然後將該面板對象作爲父項添加到所有其他小部件。 wx.Panel添加了Tab鍵功能，並使框架在所有平臺上正確（主要是正確的顏色）。如果你沒有面板，那麼Tab鍵將不起作用。
