标题:【提问】键盘问题刚刚解决，又有新的问题

内容:
在qt的source文件中，修改qt/src/kernel/qkeyboard_qws.cpp 这个文件，加上自己的键盘驱动程序，就可以完成键盘的超作。
新的问题是：在X86上，通过虚拟framebuffer，在对话框中创建一个列表框，键盘的动作在对话框和列表框中都有响应。但是，当移到target板上后，只有对话框中的keyReleaseEvent有响应，而列表框中的keyReleaseEvent没有收到任何事件，实在是不知道key event事件是怎么传递的？

请问是怎样与键盘驱动联系起来的,能否把代码贴出来看看啊

在上诉文件中在中个函数中加上你的键盘处理handle
QWSKeyboardHandler *QWSServer::newKeyboardHandler( const QString &spec )
{
QWSKeyboardHandler *handler = 0;
QString device;
QString type;
int colon=spec.find(':');
if ( colon>=0 ) {
type = spec.left(colon);
device = spec.mid(colon+1);
} else {
type = spec;
}
if ( type == "Buttons" ) {
#if defined(QT_QWS_YOPY)
qWarning( "Keyboard type %s:%s supported", spec.latin1(), device.latin1() );
handler = new QWSyopyButtonsHandler();
#elif defined(QT_QWS_CASSIOPEIA)
qWarning( "Keyboard type %s:%s supported", spec.latin1(), device.latin1() );
handler = new QWSVr41xxButtonsHandler();
#endif
} else if ( type == "QVFbKeyboard" ) {
qWarning( "Keyboard type %s:%s supported", spec.latin1(), device.latin1() );
handler = new QWSVFbKeyboardHandler();
} else if ( type == "USB" ) {
qWarning( "Keyboard type %s:%s supported", spec.latin1(), device.latin1() );
handler = new QWSUsbKeyboardHandler(device);
} else if ( type == "TTY" ) {
qWarning( "Keyboard type %s:%s supported", spec.latin1(), device.latin1() );
handler = new QWSTtyKeyboardHandler(device);
}
else if( type == "Samsung" ){
qWarning( "Keyboard type %s:%s supported", spec.latin1(), device.latin1() );   ..
