windows service后台服务怎样用qt实现

1. bool QApplication::winEventFilter ( MSG * ) 消息磨橡程序每接受消息调用函数首游帆想处理Qt处理窗口消息msg请者雹重新实现函数 1. bool MainWindow::winEvent(MSG* pMsg) 2. { 3. if ( pMsg->message == WM_COPYDATA ) 4. { 5. COPYDATASTRUCT* pCopyDataStruct6. POSTERS_REC_STRUCT* pRec7. unsigned char* odapMsgPtr[MAX_POSTERS_SIZE]8.

Some Code on the web gives another example 30. #ifdef HAVE_WIN32_API 31. virtual bool winEventFilter(MSG * msg) { 32. SPW_InputEvent sbEvent33. if (SPW_TranslateEventWin32(msg, &sbEvent)) { 34.

Modern operating systems usually provide a special area on the desktop, called the system tray or notification area, where long-running applications can display icons and short messages. 1. /* translates a Win32 event to a SPW_InputEvent. */ 2. int SPW_TranslateEventWin32(MSG * msg, SPW_InputEvent * sbEvent) 3. { 4.

1、可采用Linux下的socket编程技术，跟QT或ARM的关联性不大。

2、ARM开猜缓发板上运行多线坦昌程的服务器端程序，主线程Listen，子线程采集AD转换器的值。

3、LinuxPC上运行tcp的让兆扒客户端程序，connect到ARM开发板上的服务器进行数据获取和展现。
