wxPython中listbox用法实例详解
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
