- /////////////////////////////////////////////////////////////////////////////
- // TrayIcon.cpp : implementation file
- //
- // This is a conglomeration of ideas from the MSJ "Webster" application,
- // sniffing round the online docs, and from other implementations such
- // as PJ Naughter's "CTrayIconifyIcon" (http://indigo.ie/~pjn/ntray.html)
- // especially the "CTrayIcon::OnTrayNotification" member function.
- //
- // This class is a light wrapper around the windows system tray stuff. It
- // adds an icon to the system tray with the specified ToolTip text and
- // callback notification value, which is sent back to the Parent window.
- //
- // The tray icon can be instantiated using either the constructor or by
- // declaring the object and creating (and displaying) it later on in the
- // program. eg.
- //
- // CTrayIcon m_TrayIcon; // Member variable of some class
- //
- // ...
- // // in some member function maybe...
- // m_TrayIcon.Create(pParentWnd, WM_MY_NOTIFY, "Click here",
- // hIcon, nTrayIconID);
- //
- // Clobbered together by Chris Maunder.
- //
