2.VC设置对话框程序最小化托盘效果

1.头文件添加如下内容:

BOOL m_bTray; //托盘标记;初始元为FALSE
BOOL SetTray(BOOL bTray); //设置托盘效果
afx_msg LRESULT OnTrayCallBackMsg(WPARAM wp, LPARAM lp); //托盘处理函数

//额外还要自定义一个消息
#define WM_TRAY_MSG WM_USER+1000

2.cpp文件添加:

//消息绑定
ON_MESSAGE(WM_TRAY_MSG, &xxxDlg::OnTrayCallBackMsg)

//可在构造函数或OnInitDialog中初始化
m_bTray = FALSE;

BOOL xxxDlg::SetTray(BOOL bTray)
{
  BOOL bRet = FALSE;
  
  NOTIFYICONDATA tnd;
  tnd.cbSize = sizeof(NOTIFYICONDATA)；
  tnd.hWnd = m_hWnd;
  tnd.uID = IDR_MAINFRAME;

  if (bTray)
  {
    tnd.uFlags = NIF_MESSAGE | NIF_ICON | NIF_TIP;
    tnd.uCallbackMessage = WM_TRAY_MSG;
    tnd.hIcon = LoadIcon(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDR_MAINFRAME));
    _tcscpy_s(tnd.szTip, sizeof(tnd.szTip), _T("Tray Test.")); //最小化托盘时鼠标移到图标时的提示语
      
    bRet = Shell_NotifyIcon(NIM_ADD, &tnd);
  }
  else
  {
    bRet = Shell_NotifyIcon(NIM_DELETE, &tnd);
  }
  return bRet;
}

//响应函数处理
LRESULT xxxDlg::OnTrayCallBackMsg(WPARAM wparam, LPARAM lparam)
{
  switch(lparam)
  {
  case WM_LBUTTONDOWN:
  case WM_LBUTTONDBLCLK:
      ShowWindow(SW_RESTORE);
      break;
  case WM_RBUTTONDOWN: //右键弹出菜单
      {
        CMenu *pMenu = NULL;
        CPoint pt;
        pMenu = m_trayPopupMenu.GetSubMenu(0);
        GetCursorPos(&pt);
        pMenu->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, pt.x, pt.y, this);
        break;
      }
  default:
        break;
  }

  return 0;
}

3.上面涉及到弹出菜单， m_trayPopupMenu未定义，添加如下定义及内容:

//资源文件添加Menu,如 IDR_MENU1

显示主程序 --> ID_SHOW_MENU

退出  --> ID_EXIT_MENU

 

//.h添加

CMenu m_trayPopupMenu;

afx_msg void OnShowMenu();

afx_msg void OnExitMenu();

 

//.cpp

ON_COMMAND(ID_SHOW_MENU, &xxxDlg::OnShowMenu)

ON_COMMAND(ID_EXIT_MENU, &xxxDlg::OnExitMenu)

void xxxDlg::OnShowMenu()

{

  ShowWindow(SW_RESTORE);

}

 

void xxxDlg::OnExitMenu()

{

  SendMessage(WM_CLOSE, 0, 0);

}

 

//OnInitDialog中加载菜单栏

m_trayPopupMenu.LoadMenu(IDR_MENU1);

 

//修改 ON_WM_SYSCOMMAND() 对应的 OnSysCommand 函数，对 最小化时启动托盘 的支持

if (nID == SC_MINIMIZE)

{

  ShowWindow(SW_HIDE);

  if (!m_bTray)

  {

    SetTray(TRUE);

    m_hTray = FALSE:

  }

}
