wx上的wx.使用wx时TextCtr未调整大小.TE_MULTILINE

Question

使用下面的代码，我有两个面板，它们通过菜单进行切换。我有两个问题：

1. 行self.txtfilein1 = wx.TextCtrl(self, -1, pos=(35, 112), size=(300, 165), style = wx.TE_MULTILINE)似乎没有注意到size=(300, 165)，在使用wx.TE_MULTILINE时，它只是填充了面板。如果我取出wx.TE_MULTILINE，那么它的大小正确，问题是我需要wx.TE_MULTILINE。我上传了一张我在这里看到的照片：http://i44.tinypic.com/2wceia1.png

2. 我使用self.CreateStatusBar()在面板底部的staus栏中传递信息，例如使用self.SetStatusText("Your selected directory is: %s" % pathoutdir)，但我得到了错误AttributeError: 'PanelOne' object has no attribute 'SetStatusText'。

这是我的代码：

在wxPython 2.9的Windows 7上，我没有看到文本控件的大小问题。你使用的是什么操作系统？至于你的另一个问题，wx的反应是正确的。面板没有这种方法。您需要保存对状态栏的引用，然后以这种方式更新它。这里有一个稍微修改过的代码版本，显示了一种方法：
