使用wx.TE_MULTILINE时，wxpython wx.TextCtr没有调整大小

Question

使用下面的代码我有两个面板，通过菜单切换。 我有两个问题：

1. self.txtfilein1 = wx.TextCtrl(self, -1, pos=(35, 112), size=(300, 165), style = wx.TE_MULTILINE)行似乎没有注意size=(300, 165)，而是在使用wx.TE_MULTILINE时填充小组。如果我取出wx.TE_MULTILINE然后它的大小正确，麻烦就是我需要wx.TE_MULTILINE。我上传了一张我在这里看到的图片：http://i44.tinypic.com/2wceia1.png

2. 我正在使用self.CreateStatusBar()在我面板底部的状态栏中传递信息，例如使用self.SetStatusText("Your selected directory is: %s" % pathoutdir)，但我收到错误AttributeError: 'PanelOne' object has no attribute 'SetStatusText'

继承我的代码：

我没有看到使用wxPython 2.9的Windows 7上的文本控件的大小调整问题。你在用什么操作系统？至于你的其他问题，wx正确回应。该小组没有这种方法。您需要保存对状态栏的引用，然后以这种方式更新它。以下是代码的略微修改版本，其中显示了一种方法：
