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
