2、endif / QT_NO_QWS_KBD_MY二、在qt-4.7.0-arm/src/gui/embedded下新建qkbdmy_qws.cpp#include qkbdmy_qws.h#ifndef QT_NO_QWS_KBD_MY#include #include #include #include #include #include #include #include #include class QWSMyKbPrivate : public QObject Q_OBJECTpublic: QWSMyKbPrivate(QWSMyKeyboardHandler *handler, c
3、onst QString &device); QWSMyKbPrivate(); bool isOpen() return buttonFD 0; private Q_SLOTS: void readKeyboardData();private: QWSMyKeyboardHandler *m_handler; QString terminalName; int buttonFD; int kbdIdx; int kbdBufferLen; unsigned char *kbdBuffer; QSocketNotifier *notifier;QWSMyKeyboardHandler:QWSM
4、yKeyboardHandler(const QString &device) : QWSKeyboardHandler(device) d = new QWSMyKbPrivate(this, device);QWSMyKeyboardHandler:QWSMyKeyboardHandler() delete d;QWSMyKbPrivate:QWSMyKbPrivate(QWSMyKeyboardHandler *h, const QString &device) : m_handler(h) terminalName = device.isEmpty()?/dev/mykeyboard:
5、device.toLatin1(); buttonFD = -1; notifier = 0; if (buttonFD = QT_OPEN(terminalName.toLatin1().constData(), O_RDONLY | O_NDELAY) = 0 ) notifier = new QSocketNotifier( buttonFD, QSocketNotifier:Read, this ); connect( notifier, SIGNAL(activated(int),this,SLOT(readKeyboardData() ); kbdBufferLen = 80; k
6、bdBuffer = new unsigned char kbdBufferLen; kbdIdx = 0;QWSMyKbPrivate: QWSMyKbPrivate() if ( buttonFD 0 ) :close( buttonFD ); buttonFD = -1; delete notifier; notifier = 0; delete kbdBuffer;void QWSMyKbPrivate:readKeyboardData() int n = 0; int idx = 0; n = read(buttonFD, kbdBuffer+kbdIdx, 4); unsigned
7、 char *next = kbdBuffer + idx; int *code = (int *)next; int keycode = Qt:Key_unknown; switch ( (*code) & 0xff ) case 1: keycode = Qt:Key_Left; break; case 2: keycode = Qt:Key_Right; break; case 3: keycode = Qt:Key_Up; break; case 4: keycode = Qt:Key_Down; break; case 15: keycode = Qt:Key_cent; break
8、; default: qDebug(Unrecognised key code %d, *code ); m_handler-processKeyEvent( 0, keycode, 0, TRUE, FALSE );#include qkbdmy_qws.moc#endif / QT_NO_QWS_KBD_MY三、打开qt-4.7.0-arm/src/gui/embedded下的qkbddriverfactory_qws.cpp添加代码如下#include qapplication.h/added by Tang-#include qkbdmy_qws.h/-#include qkbdtty
9、_qws.h QString driver = key.toLower();/added by Tang-#ifndef QT_NO_QWS_KBD_MY if (driver = QLatin1String(my) | driver.isEmpty() return new QWSMyKeyboardHandler(device);#endif/-#if defined(Q_OS_QNX) & !defined(QT_NO_QWS_KBD_QNX) if (driver = QLatin1String(qnx) | driver.isEmpty() return new QWSQnxKeyboardHandler(device);#endif QStringList list;/added by Tang-#ifndef QT_NO_QWS_KBD_MY list QLatin1String(MY);#endif/-#if defined(Q_OS_QNX) & !defined(QT_NO_QWS_KBD_QNX) list QLatin1String(QNX);#endif四、打开qt-4.7.0-arm/src/gui/embedded下的embedde
