MFC 系统托盘

显示托盘

BOOL CMFCTrayDlg::OnInitDialog()
{
//...

    //设置托盘图标    
    //NOTIFYICONDATA m_NofityIcon;//.h设置为成员变量
    m_NofityIcon.cbSize = sizeof(NOTIFYICONDATA);
    m_NofityIcon.hWnd = this->m_hWnd;//图标对应的窗口
    m_NofityIcon.uFlags = NIF_MESSAGE | NIF_ICON | NIF_TIP;//图标属性
    m_NofityIcon.uCallbackMessage = WM_NOTIFY_ICON;//对应的自定义消息
    memmove(m_NofityIcon.szTip, "托盘Tip", strlen("托盘Tip")+1);//帮助信息
    m_NofityIcon.uID = IDR_MAINFRAME;//图标资源ID
    m_NofityIcon.hIcon = m_hIcon;
    ::Shell_NotifyIcon(NIM_ADD, &m_NofityIcon);//添加图标到系统状态区域

    return TRUE;  // 除非将焦点设置到控件，否则返回 TRUE
}
  

 

销毁托盘

void CMFCTrayDlg::CloseTray()
{
    ::Shell_NotifyIcon(NIM_DELETE, &m_NofityIcon);    
}

 

自定义消息

#define WM_NOTIFY_ICON WM_USER+100
LRESULT OnTrayNotification(WPARAM wParam, LPARAM lParam);

BEGIN_MESSAGE_MAP(CMFCTrayDlg, CDialog)
//...
    //}}AFX_MSG_MAP
//...
    ON_MESSAGE(WM_NOTIFY_ICON, OnTrayNotification)
END_MESSAGE_MAP()



LRESULT CMFCTrayDlg::OnTrayNotification( WPARAM wParam, LPARAM lParam )
{
    switch (lParam)
    {
    case WM_LBUTTONUP:
        {
            AfxGetApp()->m_pMainWnd->ShowWindow(SW_SHOWNORMAL);
            SetForegroundWindow();
        }
        break;
    case WM_RBUTTONUP:
        {
            //弹出菜单
            CPoint pos;
            if (GetCursorPos(&pos))
            {
                CMenu menu;
                //加载菜单资源
                menu.LoadMenu(IDR_MENU1);
                //目标子菜单是菜单资源第0列
                menu.GetSubMenu(0)->TrackPopupMenu(TPM_RIGHTBUTTON, pos.x, pos.y, this);
            }
        }
        break;
    }
    return 1;
}

 

响应弹出菜单消息

    afx_msg void OnTrayRecovery();
    afx_msg void OnTrayQuit();

BEGIN_MESSAGE_MAP(CMFCTrayDlg, CDialog)
//...
    ON_COMMAND(ID_TRAYRECOVERY, OnTrayRecovery)
    ON_COMMAND(ID_TRAYQUIT, OnTrayQuit)
    //}}AFX_MSG_MAP
//...
END_MESSAGE_MAP()


void CMFCTrayDlg::OnTrayRecovery()
{
    ShowWindow(SW_SHOWNORMAL);
    SetForegroundWindow();
}

void CMFCTrayDlg::OnTrayQuit()
{
    CloseTray();//关闭托盘
    CMFCTrayDlg::OnCancel();//退出程序
}

 

最小化时隐藏程序窗口

void CMFCTrayDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
    if (SC_MINIMIZE == nID)
    {
        ShowWindow(FALSE);
    }
    else
    {
        CDialog::OnSysCommand(nID, lParam);
    }
}

 

当然需要添加菜单资源
