VC小技巧（2）－－－－－托盘区图标操作

经常能够看到软件运行后在托盘产生图标 ，其实也就是对结构 NOTIFYICONDATA 的设置

再调用Shell_NotifyIcon就能完成

NOTIFYICONDATA notifycd;

notifycd.cbSize=sizeof(NOTIFYICONDATA);

notifycd.hIcon=AfxGetApp()->LoadIcon(IDR_MAINFRAME);//图标资源

notifycd.hWnd=m_hWnd;

notifycd.uID=IDR_MAINFRAME;

notifycd.uFlags=NIF_MESSAGE|NIF_ICON|NIF_TIP;

lstrcpy( notifycd.szTip, _T( "" ) ); //默认的tooltip上的文字

notifycd.uCallbackMessage = WM_SHELLNOTIFY; //一旦在任务栏上产生图标，就回触发一定的消息

Shell_NotifyIcon(NIM_ADD,&notifycd);

任务栏图标上的消息处理映射

ON_MESSAGE( WM_SHELLNOTIFY, OnShellNotify)

显示，删除，修改函数详细操作

//在托盘区显示图标

BOOL AddNotifyIcon(UINT Icon,LPCTSTR sztip, UINT ID)

{

HICON hIcon;

hIcon=AfxGetApp()->LoadIcon(Icon);

NOTIFYICONDATA idata;

idata.cbSize=sizeof(NOTIFYICONDATA);

idata.hIcon=hIcon;

CWnd *pWnd=AfxGetMainWnd();

idata.hWnd=GetSafeHwnd();

strcpy(idata.szTip,sztip);

idata.uCallbackMessage=WM_SHELLNOTIFY;

idata.uFlags=NIF_MESSAGE|NIF_ICON|NIF_TIP;

idata.uID=ID;

return Shell_NotifyIcon(NIM_ADD,&idata);

}

//在托盘区删除图标

BOOL DeleteNotifyIcon(UINT Icon,LPCTSTR sztip, UINT ID)

{

HICON hIcon;

hIcon=AfxGetApp()->LoadIcon(Icon);

NOTIFYICONDATA idata;

idata.cbSize=sizeof(NOTIFYICONDATA);

idata.hIcon=hIcon;

CWnd *pWnd=AfxGetMainWnd();

idata.hWnd=GetSafeHwnd();

strcpy(idata.szTip,sztip);

idata.uCallbackMessage=WM_SHELLNOTIFY;

idata.uFlags=NIF_MESSAGE|NIF_ICON|NIF_TIP;

idata.uID=ID;

return Shell_NotifyIcon(NIM_DELETE,&idata);

}

//在托盘区修改图标

BOOL ModifyNotifyIcon(UINT Icon,LPCTSTR sztip, UINT ID)

{

HICON hIcon;

hIcon=AfxGetApp()->LoadIcon(Icon);

NOTIFYICONDATA idata;

idata.cbSize=sizeof(NOTIFYICONDATA);

idata.hIcon=hIcon;

CWnd *pWnd=AfxGetMainWnd();

idata.hWnd=GetSafeHwnd();

strcpy(idata.szTip,sztip);

idata.uCallbackMessage=WM_SHELLNOTIFY;

idata.uFlags=NIF_MESSAGE|NIF_ICON|NIF_TIP;

idata.uID=ID;

return Shell_NotifyIcon(NIM_MODIFY,&idata);

}
