VC Tray Icon的使用

为CMainFrame增加如下的成员变量：

NOTIFYICONDATA m_trayIcon;

CMenu m_menuTray;

在CMainFrame的OnCreate函数末尾增加：

m_trayIcon.cbSize = sizeof(NOTIFYICONDATA);

m_trayIcon.hIcon = (HICON)LoadImage(AfxGetApp()->m_hInstance,

MAKEINTRESOURCE(IDI_TRAYICON), IMAGE_ICON, 16, 16, 0);

m_trayIcon.hWnd = m_hWnd;

m_trayIcon.uID = MAINTRAYICON;

m_trayIcon.uFlags = NIF_MESSAGE | NIF_ICON | NIF_TIP;

m_trayIcon.uCallbackMessage = WM_TRAYICON;

strcpy(m_trayIcon.szTip, LoadResString(IDS_TOOLTIP));

Shell_NotifyIcon(NIM_ADD, &m_trayIcon);

增加消息WM_TRAYICON响应函数：

ON_MESSAGE(WM_TRAYICON,OnTrayNotify)

int CMainFrame::OnTrayNotify(WPARAM wParam, LPARAM lParam)

{

if(wParam != MAINTRAYICON)

return 0L;

if(m_menuTray.m_hMenu == NULL && !m_menuTray.LoadMenu(IDR_MAINFRAME))

return 0;

CMenu* pSubMenu = m_menuTray.GetSubMenu(0);

if (!pSubMenu)

return 0;

if (lParam == WM_RBUTTONUP)

{

::SetMenuDefaultItem(pSubMenu->m_hMenu, 0, TRUE);

CPoint pos;

GetCursorPos(&pos);

SetForegroundWindow();

pSubMenu->TrackPopupMenu(TPM_RIGHTALIGN|TPM_LEFTBUTTON

|TPM_RIGHTBUTTON, pos.x, pos.y, this, NULL);

}

else if(lParam == WM_LBUTTONDOWN)

{

ShowWindow(SW_SHOW);

SetForegroundWindow();

}

else if(lParam == WM_LBUTTONDBLCLK)

{

SendMessage(WM_COMMAND, pSubMenu->GetMenuItemID(0), 0);

}

return 1L;

}

如果同时还需要屏蔽窗口关闭按钮的话需要增加消息处理函数：

ON_WM_SYSCOMMAND()

void CMainFrame::OnSysCommand(UINT nID, LPARAM lParam)

{

if(nID == SC_CLOSE)

{

ShowWindow(SW_HIDE);

return;

}

CFrameWnd::OnSysCommand(nID, lParam);

}

在窗口的Destroy函数调用：

Shell_NotifyIcon(NIM_DELETE, &m_trayIcon);
