yipeiwu_com6年前Python基础

本文实例讲述了wxPython中listbox用法。分享给大家供大家参考。具体如下:

# load a listbox with names, select a name and display in title
# experiments with wxPython by vegaseat 20mar2005
# Python v2.4 and wxPython v2.5
# If you have not already done so, install Python 2.4 first.
# I used python-2.4.1c2.msi (this is the self-extracting
# MS-Installer file) from http://www.python.org
# Then install wxPython2.5-win32-unicode-2.5.4.1-py24.exe
# from: http://prdownloads.sourceforge.net/wxpython/
# (if you don't get into unicode, download the ansi version)
# note: python-2.4.1c2.msi should soon be python-2.4.1.msi
import wx

  return Frame1(parent)
# assign ID numbers
[wxID_FRAME1, wxID_FRAME1BUTTON1, wxID_FRAME1BUTTON2, wxID_FRAME1LISTBOX1, 
] = [wx.NewId() for _init_ctrls in range(4)]

    # BOA generated methods

       id=wxID_FRAME1BUTTON2)
  def __init__(self, parent):
    self._init_ctrls(parent)
  def OnButton1Button(self, event):
    '''
    click button to load the listbox with names
    '''
    self.listBox1.Append("Andreas")
    self.listBox1.Append("Erich")
    self.listBox1.Append("Udo")
    self.listBox1.Append("Jens")
    self.listBox1.Append("Bjorn")

    self.listBox1.Append("Ulla")
    self.listBox1.Append("Volger")
    self.listBox1.Append("Helmut")

    '''
    click list item and display the selected string in frame's title
    '''
    selName = self.listBox1.GetStringSelection()
    self.SetTitle(selName)
  def OnButton2Button(self, event):
    '''
    click button to clear the listbox items
    '''
    self.listBox1.Clear()
#--------------- end of class Frame1 --------------------
# program entry point ...
if __name__ == '__main__':
  app = wx.PySimpleApp()
  wx.InitAllImageHandlers()
  frame = create(None)
  frame.Show()
  app.MainLoop()
