wXPython：無法獲取小部件以放大/擴大尺寸

Question

我無法獲取listctrl小部件以進行展開。

例如圖片：http://img109.imageshack.us/img109/3171/22488459.jpg

此代碼簡單地創建一個對話框，並創建一個CheckListCtrlMixin這與複選框一個的ListCtrl。

import wx 
import re, os, sys 
from wx.lib.mixins.listctrl import CheckListCtrlMixin, ListCtrlAutoWidthMixin 

class CheckListCtrl(wx.ListCtrl, CheckListCtrlMixin, ListCtrlAutoWidthMixin): 
    def __init__(self, parent): 
     wx.ListCtrl.__init__(self, parent, -1, style=wx.LC_REPORT | wx.SUNKEN_BORDER) 
     CheckListCtrlMixin.__init__(self) 
     ListCtrlAutoWidthMixin.__init__(self) 

class QueueDialog(wx.Dialog): 

    def __init__(self, parent, title): 
     super(QueueDialog, self).__init__(parent=parent, 
      title=title, size=(400, 500)) 


     panel = wx.Panel(self) 
     vbox = wx.BoxSizer(wx.VERTICAL) 


     sb = wx.StaticBox(panel, label='Queue') 
     sbs = wx.StaticBoxSizer(sb, orient=wx.VERTICAL) 
     panel2 = wx.Panel(panel) 
     hbox3 = wx.BoxSizer(wx.VERTICAL) 
     hbox3.Add(panel2, proportion=1, flag=wx.EXPAND|wx.ALL) 

     listB = CheckListCtrl(panel2) 
     listB.InsertColumn(0, "Test", width=100) 
     listB.InsertColumn(1, "Status", wx.LIST_FORMAT_RIGHT) 

     dalist = ["heh", "ha", "hello"] 
     for name in dalist[0:3]: 
      index = listB.InsertStringItem(sys.maxint, name[0:-1]) 


     sbs.Add(hbox3, proportion=1,flag=wx.EXPAND|wx.ALL) 

     panel.SetSizer(sbs) 


     hbox2 = wx.BoxSizer(wx.HORIZONTAL) 

     okButton = wx.Button(self, label='OK') 
     closeButton = wx.Button(self, label='Cancel') 
     hbox2.Add(okButton) 
     hbox2.Add(closeButton, flag=wx.LEFT, border=5) 
     vbox = wx.BoxSizer(wx.VERTICAL) 
     vbox.Add(panel, proportion=1, flag=wx.EXPAND|wx.ALL, border=10) 
     vbox.Add(hbox2, flag= wx.ALIGN_CENTER|wx.BOTTOM, border=10) 

     self.SetSizer(vbox) 

    def OnClose(self, e): 
     self.Destroy() 


class window(wx.Frame): 
    def __init__(self, parent, id, title): 
     wx.Frame.__init__(self, parent, id, title, size=(600, 400)) 

     e = QueueDialog(None, title='Queue') 
     e.ShowModal() 
     e.Destroy() 

     self.Centre() 
     self.Show(True) 

app = wx.App(0) 
window(None, -1, 'e') 
app.MainLoop()

我不知道你爲什麼有第二個面板，但它確實不需要，使事情變得更加複雜。這裏有一個版本適用於我的機器：

import wx 
import re, os, sys 
from wx.lib.mixins.listctrl import CheckListCtrlMixin, ListCtrlAutoWidthMixin 

class CheckListCtrl(wx.ListCtrl, CheckListCtrlMixin, ListCtrlAutoWidthMixin): 
    def __init__(self, parent): 
     wx.ListCtrl.__init__(self, parent, -1, style=wx.LC_REPORT | wx.SUNKEN_BORDER) 
     CheckListCtrlMixin.__init__(self) 
     ListCtrlAutoWidthMixin.__init__(self) 

class QueueDialog(wx.Dialog): 

    def __init__(self, parent, title): 
     super(QueueDialog, self).__init__(parent=parent, 
      title=title, size=(400, 500)) 


     panel = wx.Panel(self) 
     vbox = wx.BoxSizer(wx.VERTICAL) 

     sb = wx.StaticBox(panel, label='Queue') 
     sbs = wx.StaticBoxSizer(sb, orient=wx.VERTICAL) 

     hbox3 = wx.BoxSizer(wx.VERTICAL) 
     listB = CheckListCtrl(panel) 
     listB.InsertColumn(0, "Test", width=100) 
     listB.InsertColumn(1, "Status", wx.LIST_FORMAT_RIGHT) 
     hbox3.Add(listB, 1, wx.EXPAND) 

     dalist = ["heh", "ha", "hello"] 
     for name in dalist[0:3]: 
      index = listB.InsertStringItem(sys.maxint, name[0:-1]) 

     sbs.Add(hbox3, proportion=1,flag=wx.EXPAND|wx.ALL) 
     panel.SetSizer(sbs) 

     hbox2 = wx.BoxSizer(wx.HORIZONTAL) 

     okButton = wx.Button(self, label='OK') 
     closeButton = wx.Button(self, label='Cancel') 
     hbox2.Add(okButton) 
     hbox2.Add(closeButton, flag=wx.LEFT, border=5) 
     vbox = wx.BoxSizer(wx.VERTICAL) 
     vbox.Add(panel, proportion=1, flag=wx.EXPAND|wx.ALL, border=10) 
     vbox.Add(hbox2, flag= wx.ALIGN_CENTER|wx.BOTTOM, border=10) 

     self.SetSizer(vbox) 

    def OnClose(self, e): 
     self.Destroy() 


class window(wx.Frame): 
    def __init__(self, parent, id, title): 
     wx.Frame.__init__(self, parent, id, title, size=(600, 400)) 

     e = QueueDialog(None, title='Queue') 
     e.ShowModal() 
     e.Destroy() 

     self.Centre() 
     self.Show(True) 

app = wx.App(0) 
window(None, -1, 'e') 
app.MainLoop()
