开始做植化了，要用，鑫哥的那个是 for win 的,以前写了个 ruby-gtk 的不知道扔哪里去了，于是重新写了个 pyqt 的。

ps： 图形界面的程序真是浪费表情阿，真正干活的就两三行，一旦要图形界面了就几百行，这个看来是死要面子（图形界面）活受罪的真实写照阿，呵呵。

    这写得也太累了，全人工布局，要个几百行还真正常，虽然是pyqt，但好歹布局管理器也有吧，还字体属性等，定义一个模板出来，然后赋值不就好了。。那么多code，看得我心惊肉跳

    呵呵，看起来是吓人哈，其实那个是用qt-designer自动生成的，就是用鼠标拖放控件，画好了以后转换成python代码，手工写的也就十几行吧。
