wxpython wx.TextCtr使用wx.TE_MULTILINE時不會調整大小

Question

使用下面的代碼我有兩個面板，它們通過菜單進行切換。 我有兩個問題：

1. 線self.txtfilein1 = wx.TextCtrl(self, -1, pos=(35, 112), size=(300, 165), style = wx.TE_MULTILINE)似乎並不注意size=(300, 165)，它比填充面板，同時採用wx.TE_MULTILINE。如果我拿出wx.TE_MULTILINE那麼它的大小正確，麻煩是我需要wx.TE_MULTILINE。我已經上傳awhat的形象，我在這裏看到：http://i44.tinypic.com/2wceia1.png

2. 我使用self.CreateStatusBar()通過在我的面板底部的居留制條信息，例如通過使用self.SetStatusText("Your selected directory is: %s" % pathoutdir)，但我得到的錯誤AttributeError: 'PanelOne' object has no attribute 'SetStatusText' 。

繼承人我的代碼：

我沒有看到在Windows 7中的文本控件的wxPython 2.9上漿問題。你在什麼操作系統上？至於你的其他問題，wx正確響應。該面板沒有這種方法。您需要保存對狀態欄的引用，然後以此方式進行更新。這裏有一個稍微修改版本的代碼，顯示了一種方法：
