用python加wxpython写的查看Jboss日志的小程序
在查看Jboss日志时，文件大了的话不好操作，所以自己用Python写了一个查看Jboss日志的工具，对工作还是有点帮助的
# -*- encoding:GBK -*-"""author:xieguozhongemail:superxgz@gmail.com修订历史：V0.3 2009-04-301 修改为实时跟踪日志2 将原来的按钮修正为"启动,暂停,复制,清除"V0.2 2009-03-131 增加了初始化文件时就定位到日志结尾,无须再点"Clear"按钮2 增加了复制按钮3 增加了最小化按钮4 增加了日志显示框的横拉条,并使显示框为只读5 增加了JBOSS路径的保存功能,可以删除和增加V0.1 不记得了"""import wximport osimport timeimport threadingfrom wx.lib.wordwrap import wordwrapimport wx.lib.buttons as buttonsimport wx.richtext as
