MFC下托盘图标的实现和托盘菜单

转载自：http://blog.csdn.net/longsir2008/article/details/6304130

对话框头文件XXXDlg.h:

1.添加成员变量NOTIFYICONDATA m_nid;

2.添加tray消息响应函数的声明

afx_msg LRESULT OnTrayNotify(WPARAM wParam, LPARAM lParam);

对话框实现文件XXXDlg.cpp:

1.定义tray消息 #define UM_TRAYNOTIFY WM_USER + 11

2.CXXXDlg的构造函数添加

memset(&m_nid, 0, sizeof(m_nid)); // Initialize NOTIFYICONDATA struct

m_nid.cbSize = sizeof(m_nid);

m_nid.uFlags = NIF_ICON | NIF_TIP | NIF_MESSAGE;

3.CXXXDlg的析构函数添加

m_nid.hIcon = NULL;

Shell_NotifyIcon(NIM_DELETE, &m_nid);

4.添加消息映射：

BEGIN_MESSAGE_MAP(CMFC2Dlg, CDialog)

//...

ON_MESSAGE(UM_TRAYNOTIFY, &CMFC2Dlg::OnTrayNotify)

//...

END_MESSAGE_MAP()

5.OnInitDialog函数添加：

m_nid.hWnd = GetSafeHwnd();

m_nid.uCallbackMessage = UM_TRAYNOTIFY;

// Set tray icon and tooltip

m_nid.hIcon = m_hIcon;

// Set tray notification tip information

CString strToolTip = _T("托盘程序");

_tcsncpy_s(m_nid.szTip, strToolTip, strToolTip.GetLength());

Shell_NotifyIcon(NIM_ADD, &m_nid);

6.OnTrayNotify函数的实现：

LRESULT CXXXDlg::OnTrayNotify(WPARAM wParam, LPARAM lParam)

{

UINT uMsg = (UINT)lParam;

switch(uMsg)

{

case WM_RBUTTONUP:

{

//右键处理

CMenu menuTray;

CPoint point;

int id;

GetCursorPos(&point);

menuTray.LoadMenu(IDR_MENU_TRAY);

id = menuTray.GetSubMenu(0)->TrackPopupMenu(TPM_RETURNCMD | TPM_LEFTALIGN|TPM_RIGHTBUTTON, point.x, point.y, this);

#if 0

CString strInfo;

strInfo.Format(L"menuid %d", id);

LPCTSTR strtmp;

strtmp = strInfo.GetBuffer(0);

MessageBox(strtmp, L"test");

#endif

switch(id){

case IDR_TRAY_EXIT:

OnOK();

break;

case IDR_TRAY_RESTORE:

//窗口前端显示

SetForegroundWindow();

ShowWindow(SW_SHOWNORMAL);

break;

default:

break;

}

break;

}

case WM_LBUTTONDBLCLK:

SetForegroundWindow();

ShowWindow(SW_SHOWNORMAL);

break;

default:

break;

}

return 0;

}

7.添加WM_SIZE消息处理：

void CMFC2Dlg::OnSize(UINT nType, int cx, int cy)

{

CDialog::OnSize(nType, cx, cy);

if(nType == SIZE_MINIMIZED){

ShowWindow(SW_HIDE);

}

}

8.菜单。

添加菜单资源 , 比如IDR_MENU_TRAY.

定义一个子菜单Tray，有若干个菜单项，比如“恢复窗口”, ID是IDR_TRAY_RESTORE，“退出”, ID是IDR_TRAY_EXIT。

在OnTrayNotify函数中捕获右击消息，弹出菜单，参考第6步。

至此，添加托盘的功能基本完成。
