wxpython：防止特定字段的水平增长

Question

我有一个gui有3个基本区域。一个列表控件，它跨越窗口的整个宽度，位于根据按钮功能分组的两个按钮区域上方。

当调整窗口大小时，所有3个区域的大小将与窗口的增长成比例。我想要发生的是两个按钮区域不能做任何高度增长，但会允许宽度增长。

这可能吗？

以下是我用作示例。我使用wxGlade生成了这个

喜欢这个？

import wx 


class Frame(wx.Frame): 
    def __init__(self): 
     wx.Frame.__init__ (self, None) 
     self.SetBackgroundColour(wx.GREEN) 

     bSizer1 = wx.BoxSizer(wx.VERTICAL) 

     panel1 = wx.Panel(self) 
     bSizer1.Add(panel1, 1, wx.EXPAND | wx.ALL, 5) 

     bSizer2 = wx.BoxSizer(wx.HORIZONTAL) 

     panel2 = wx.Panel(self, size=(-1, 50)) 
     bSizer2.Add(panel2, 1, wx.EXPAND | wx.ALL, 5) 

     panel3 = wx.Panel(self, size=(-1, 50)) 
     bSizer2.Add(panel3, 1, wx.EXPAND | wx.ALL, 5) 

     bSizer1.Add(bSizer2, 0, wx.EXPAND, 5) 

     self.SetSizer(bSizer1) 


app = wx.PySimpleApp() 
app.TopWindow = f = Frame() 
f.Show() 
app.MainLoop()
