托盘功能实现三步曲

1. 隐藏窗体

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)

{

         if( !CFrameWnd::PreCreateWindow(cs) )

                  return FALSE;

         cs.style = WS_POPUP;//使主窗口不可见

         cs.dwExStyle = WS_EX_TOOLWINDOW;//不显示任务按钮

         cs.lpszClass = AfxRegisterWndClass(0);

         return TRUE;

}

2. 增加托盘

CMainFrame类中增加变量

         NOTIFYICONDATA m_tnid; 

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)函数返回前增加如下代码

m_tnid.cbSize = sizeof(NOTIFYICONDATA);  

         m_tnid.hWnd = this->m_hWnd;  

         m_tnid.uFlags = NIF_MESSAGE | NIF_ICON | NIF_TIP;  

         m_tnid.uCallbackMessage = MYWM_NOTIFYICON;     

         CString szToolTip = _T("故¨º障?辅¡§助¨²");

         _tcscpy(m_tnid.szTip, szToolTip);  

         m_tnid.uID = IDR_MAINFRAME;  

         HICON hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);  

         m_tnid.hIcon = hIcon;  

         ::Shell_NotifyIcon(NIM_ADD, &m_tnid);  

         if(hIcon)

         {

                  ::DestroyIcon(hIcon);

         }

3. 消息处理

LRESULT CMainFrame::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)     

{

         switch(message)

         {

         case MYWM_NOTIFYICON:

                  if(lParam == WM_LBUTTONDBLCLK)  

                  {  

                          AfxGetApp()->m_pMainWnd->ShowWindow(SW_SHOW);  

                  } 

                  else if(lParam == WM_RBUTTONDOWN)

                  {     

                          CMenu menu;

                          menu.LoadMenu(IDR_MAINFRAME);     

                          CMenu* pMenu=menu.GetSubMenu(0);  

                          CPoint pos;  

                          GetCursorPos(&pos);  

                           pMenu->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON,pos.x,pos.y,AfxGetMainWnd());  

                  }

                  break;  

         case WM_SYSCOMMAND:

                  switch(wParam)

                  { 

                  case SC_MINIMIZE:                           

                          ShowWindow(SW_HIDE);  

                          break; 

                  case SC_CLOSE : 

                          ::Shell_NotifyIcon(NIM_DELETE, &m_tnid);  

                          break; 

                  }  

                  break;  

         }

         return CFrameWnd::WindowProc(message, wParam, lParam); 

}
