Duilib 实现窗口点击关闭确认退出提示

此功能是记住用户的操作，在用户点击关闭时是真退出程序还是最小化到托盘，我们常见的PC客户端都有此功能，例如:IMO客户端、网易云音乐

我自己的项目中也要实现此功能，在此总结一下，最终效果:

1.最小化托盘原理: 首先要将窗口隐藏，然后在右下角绘制托盘图标

2.恢复的原理：将窗口显示

在点击关闭按钮响应函数里面处理:

 1 bool OnExitConfirm()
 2 {
 3     bool bResult = false;
 4     //从配置文件中读取用户设置
 5     TCHAR cofigValue[MAX_PATH];
 6     CString tszModule = CommonUtils::GetModuleDirectory();
 7     tszModule+="\config.ini";
 8     ::GetPrivateProfileString(L"Setting",L"ExitDirect",L"Error",cofigValue,MAX_PATH,tszModule);
 9 
10     if (_tcsicmp(cofigValue,_T("Error")) == 0)//配置文件里面没有
11     {
12         CCloseHintDialog closeHintBox;

恢复界面函数

 1 LRESULT CMainFrameWnd::OnTrayNotify(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
 2 {

10             {
11                 ::ShowWindow(this->GetHWND(),SW_SHOW);//显示窗口
