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:

 bool OnExitConfirm()
 {
     bool bResult = false;
     //从配置文件中读取用户设置
     TCHAR cofigValue[MAX_PATH];
     CString tszModule = CommonUtils::GetModuleDirectory();
     tszModule+="\\config.ini";
     ::GetPrivateProfileString(L"Setting",L"ExitDirect",L"Error",cofigValue,MAX_PATH,tszModule);

     if (_tcsicmp(cofigValue,_T("Error")) == )//配置文件里面没有
     {
         CCloseHintDialog closeHintBox;
         closeHintBox.Create(this->GetHWND(), _T("CloseHintDialog"), UI_WNDSTYLE_EX_FRAME, WS_EX_WINDOWEDGE);
         closeHintBox.CenterWindow();

         if(closeHintBox.ShowModal()== IDOK)
         {
             if (closeHintBox.m_pchkOption->GetCheck())//勾选
             {
                 if(closeHintBox.m_pExitbtn->IsSelected())
                 {
                     CString strExit;
                     strExit.Format(L"%d",);
                     ::WritePrivateProfileString(L"Setting",L"ExitDirect",strExit,tszModule);

                     Close(IDCLOSE);

                     bResult = true;

                     return bResult;

                 }
                 else if (closeHintBox.m_pMoveToTraybtn->IsSelected())
                 {
                     CString strExit;
                     strExit.Format(L"%d",);
                     ::WritePrivateProfileString(L"Setting",L"ExitDirect",strExit,tszModule);

                     ::ShowWindow(this->GetHWND(),SW_HIDE);

                     return bResult;
                 }
             }
             else//不勾选
             {
                 if(closeHintBox.m_pExitbtn->IsSelected())
                 {
                     Close(IDCLOSE);

                     bResult = true;

                     return bResult;
                 }
                 else if (closeHintBox.m_pMoveToTraybtn->IsSelected())
                 {
                     ::ShowWindow(this->GetHWND(),SW_HIDE);
                     return bResult;
                 }
             }
         }
         else
         {
             return bResult;
         }
     }
     else
     {
         if (_tcsicmp(cofigValue,_T("")) == )
         {
             Close(IDCLOSE);

             bResult = true;

             return bResult;
         }
         else if (_tcsicmp(cofigValue,_T("")) == )
         {
             ::ShowWindow(this->GetHWND(),SW_HIDE);
             return bResult;
         }
     }

     return bResult;
 }

恢复界面函数

 LRESULT CMainFrameWnd::OnTrayNotify(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
 {
     if(wParam == )
     {
         switch(lParam)
         {
                ...

         case WM_LBUTTONDBLCLK:
             {
                 ::ShowWindow(this->GetHWND(),SW_SHOW);//显示窗口
             }
             break;
         }
     }
     return ;
 }
