Example #1

File: main.cpp Project: zccrs/qt-mobility

int main(int argc, char **argv)
{
    QCoreApplication app(argc, argv);
    QStringList args = app.arguments();
    int rate_place = args.indexOf("-r");
    int rate_val = 0;
    if (rate_place != -1)
        rate_val = args.at(rate_place + 1).toInt();

    sensor.setProperty("bufferSize",bufferSize);

    sensor.setProperty("bufferInOneShot",args.indexOf("-bb")>-1);
