系统托盘气泡提示和右键菜单的实现_Java教程

WTL嵌入类的架构可以使整个程序很清楚，系统托盘气泡提示、上下文菜单处理可以分别独立出来，以下是实现代码，很清楚就不注释了。基本上这两个类很少需要修改，因此我把它们放到了系统包含文件搜索路径中。

//ContextMenu.h

public:

GetCursorPos(&pos);
SubMenu.TrackPopupMenu(TPM_LEFTALIGN  TPM_RIGHTBUTTON, pos.x, pos.y, pT->m_hWnd);
return TRUE;
}
};

//去掉下面的注释可以使鼠标悬停在图标上时出现气泡提示，个人不太喜欢

//处理EXPlorer外壳崩溃后任务栏重建，你会发现很多程序都没处理，结果就是Explorer一崩溃
//图标就找不到了，假如最小化到任务栏更惨，还得用任务治理器关闭，这个函数我没机会测试，希望有作用
