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")) == 0)//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",1);
                    ::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",0);
                    ::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("1")) == 0)
        {
            Close(IDCLOSE);

            bResult = true;

            return bResult;
        }
        else if (_tcsicmp(cofigValue,_T("0")) == 0)
        {
            ::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 == 1000)
    {
        switch(lParam)
        {
               ...

        case WM_LBUTTONDBLCLK:
            {
                ::ShowWindow(this->GetHWND(),SW_SHOW);//显示窗口
            }
            break;
        }
    }
    return 0;
}
