一直在学习系统托盘的实现，于是自己写了一个简单的系统托盘实例，右键包括演示、最大化、最小化、退出和关于。在python2.6下测试通过。
注意，本节分享的python实例代码，这里是托盘上的图标弹出菜单是覆盖了CreatePopupMenu。
也可以绑定2个方法，一个wx.EVT_TASKBAR_RIGHT_DOWN，方法里面生成menu，然后再来一个wx.EVT_MENU，定义要处理的事件函数。
还有一个就是Wx窗体上的最小化按钮，触发的事件是 wx.EVT_ICONIZE,而根本就没有定义什么wx.EVT_MINIMIZE,但是最大化，有个wx.EVT_MAXIMIZE。
复制代码 代码如下:
