wxpython：防止特定字段的水平增长

如何解决wxpython：防止特定字段的水平增长

| 我有3个基本方面的GUI。一个列表控件，该控件跨越按钮的两个区域上方的窗口的整个宽度，该区域根据按钮的功能进行分组。 调整窗口大小时，所有3个区域的大小都会与窗口的增长成比例地调整。我想发生的是两个按钮区域不进行任何高度增长，但允许宽度增长。 这可能吗？ 这是我使用的示例。我使用wxGlade生成了

解决方法

import wx

class MainWindow(wx.Frame):
    def __init__(self,*args,**kwargs):
        wx.Frame.__init__(self,**kwargs)
        self.panel1 = wx.Panel(self)
        self.panel1.SetBackgroundColour(wx.GREEN)
        self.panel2 = wx.Panel(self)
        self.panel2.SetBackgroundColour(wx.RED)
        self.panel3 = wx.Panel(self)
        self.panel3.SetBackgroundColour(wx.WHITE)

        self.sizer1 = wx.BoxSizer()
        self.sizer2 = wx.BoxSizer(wx.VERTICAL)
        self.sizer1.Add(self.panel1,proportion=1,flag=wx.EXPAND)
        self.sizer1.Add(self.panel2,flag=wx.EXPAND)
        self.sizer2.Add(self.panel3,flag=wx.EXPAND)
        self.sizer2.Add(self.sizer1,proportion=0,flag=wx.EXPAND)

        self.SetSizerAndFit(self.sizer2)       
        self.Show()

app = wx.App(False)
win = MainWindow(None)
app.MainLoop()

    ,像这样？

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(panel2,5)

        panel3 = wx.Panel(self,50))
        bSizer2.Add(panel3,5)

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

        self.SetSizer(bSizer1)


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