wxPython，使用SplitterWindow

我想把TreeCtrl放在SplitterWindow的两侧。当然，TreeCtrl应该随着窗口的大小而扩展

splitter  = wx.SplitterWindow(self, style = wx.SP_BORDER)

leftPanel = wx.Panel(splitter)
rightPanel  = wx.Panel(splitter)

leftSizer = wx.BoxSizer(wx.VERTICAL)
rightSizer  = wx.BoxSizer(wx.VERTICAL)

localTree = wx.TreeCtrl(leftPanel)
flickrTree  = wx.TreeCtrl(rightPanel)

leftSizer.Add(localTree, flag = wx.EXPAND | wx.ALIGN_CENTER)
rightSizer.Add(flickrTree, flag = wx.EXPAND)

splitter.SplitVertically(leftPanel, rightPanel)
leftPanel.SetSizer(leftSizer)
leftPanel.SetAutoLayout(1)
leftSizer.Fit(leftPanel)

我试过上面的代码，但TreeCtrl的高度并没有像我预期的那样扩展

有什么问题吗？

以下内容对我很有用：

splitter = wx.SplitterWindow(self, style = wx.SP_BORDER)
leftPanel = wx.Panel(splitter)
rightPanel = wx.Panel(splitter)

localTree = wx.TreeCtrl(leftPanel)
leftSizer = wx.BoxSizer(wx.VERTICAL)
leftSizer.Add(localTree, 1, wx.EXPAND | wx.ALL)
leftPanel.SetSizer(leftSizer)

flickrTree  = wx.TreeCtrl(rightPanel)
rightSizer = wx.BoxSizer(wx.VERTICAL)
rightSizer.Add(flickrTree, 1, wx.EXPAND | wx.ALL)
rightPanel.SetSizer(rightSizer)

splitter.SplitVertically(leftPanel, rightPanel)

关键是在将TreeCtrl添加到BoxSizer时设置比例值，即：

添加（localTree，1，wx.EXPAND | wx.ALIGN_CENTER）

而不是：

leftSizer.Add（localTree，flag=wx.EXPAND | wx.ALIGN_CENTER）

否则，它默认为零
