function GetSysTrayIconRect(Text: string): TRect;
{
  返回系统托盘中指定文字的图标的矩形区域。
  例如返回音量控制图标的矩形区域:
  GetSysTrayIconRect('音量');
}

begin
  result := GetToolBarButtonRect(GetSysTrayWnd, Text);
end;

function GetSysTrayWnd: HWND;
{
  返回系统托盘的句柄,适合于WinXP以上版本
}

begin

  result := FindWindowEx(result, 0, 'TrayNotifyWnd', nil);
  result := FindWindowEx(result, 0, 'SysPager', nil);
  result := FindWindowEx(result, 0, 'ToolbarWindow32', nil);
end;

function GetToolBarButtonRect(hWnd: HWND; Title: string): TRect;
{
  返回指定工具栏对应的按钮指定文本的矩形区域
  hWnd:工具栏句柄,Title:需要返回矩形区域的按钮文字
  返回值:指定按钮的边界矩形,屏幕坐标
}
