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 ;
}
