void CentralWidget::setDrivePlateAddrAndElectronStorageCabinetCount(int drivePlateAddr, int electronStorageCabinetCount)
{
    int prevCount = info->getElectronStorageCabinetCount();

    for(int i = 0; i < prevCount; ++i)
    {
        delete labels[i];
        labels[i] = NULL;
    }

    labels.clear();

    for(int i = 0; i < electronStorageCabinetCount; ++i)
        labels.append(new Label(this));

    for(int i = 0; i < electronStorageCabinetCount; ++i)
    {
        int row = i / LINE_COUNT;
        int column = i % LINE_COUNT;
        gridLayout->addWidget(labels[i], row, column);
    }

    for(int i = 0; i < labels.count(); ++i)
    {
        connect(labels[i], SIGNAL(updateBoxDoorCheckState(int)), this, SLOT(updateBoxDoorCheckState(int)));
        connect(labels[i], SIGNAL(updateGoodsCheckState(int)), this, SLOT(updateGoodsCheckState(int)));
    }

    info->initInfo(drivePlateAddr, electronStorageCabinetCount);
}
