system tray 源码MFC and SDK

///////////////////////////////////////////////////////////////////////////// // SystemTray.cpp : implementation file // // MFC VERSION // // 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 "CTrayNotifyIcon" (http://indigo.ie/~pjn/ntray.html) // especially the "CSystemTray::OnTrayNotification" member function. // Joerg Koenig suggested the icon animation stuff // // 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. // // CSystemTray m_SystemTray; // Member variable of some class // // ... // // in some member function maybe... // m_SystemTray.Create(pParentWnd, WM_MY_NOTIFY, "Click here", // hIcon, nSystemTrayID); // // Written by Chris Maunder (cmaunder@mail.com) // Copyright (c) 1998-2003. // // Updated: 25 Jul 1998 - Added icon animation, and derived class // from CWnd in order to handle messages. (CJM) // (icon animation suggested by Joerg Koenig. // Added API to set default menu item. Code provided // by Enrico Lelina. // // Updated: 6 June 1999 - SetIcon can now load non-standard sized icons (Chip Calvert) // Added "bHidden" parameter when creating icon // (Thanks to Michael Gombar for these suggestions) // Restricted tooltip text to 64 characters. // // Updated: 9 Nov 1999 - Now works in WindowsCE. // Fix for use in NT services (Thomas Mooney, TeleProc, Inc) // Added W2K stuff by Michael Dunn // // Updated: 1 Jan 2000 - Added tray minimisation stuff. // // Updated: 21 Sep 2000 - Added GetDoWndAnimation - animation only occurs if the system // settings allow it (Matthew Ellis). Updated the GetTrayWndRect // function to include more fallback logic (Matthew Ellis) // NOTE: Signature of GetTrayWndRect has changed! // // Updated: 4 Aug 2003 - Fixed bug that was stopping icon from being recreated when // Explorer crashed // Fixed resource leak in SetIcon // Animate() now checks for empty icon list - Anton Treskunov // Added the virutal CustomizeMenu() method - Anton Treskunov // // // This code may be used in compiled form in any way you desire.
