    ui->lvicons->setIconSize(QSize(60, 60));

    ui->lvicons->setGridSize(QSize(60, 60));

    ui->lvicons->setViewMode(QListView::IconMode);

    ui->lvicons->addItem(new QListWidgetItem(QIcon(":/ReceiveBox.png"), "receive"));

    ui->lvicons->addItem(new QListWidgetItem(QIcon(":/DraftBox.png"), "draft"));

    ui->lvicons->addItem(new QListWidgetItem(QIcon(":/SendBox.png"), "send"));

    ui->lvicons->setDragEnabled(false);

m_recvmodel = new QStandardItemModel;

    m_sendmodel = new QStandardItemModel;

    m_draftmodel = new QStandardItemModel;

  ui->m_smsrecv->setModel(m_recvmodel);

    ui->m_smssend->setModel(m_sendmodel);

    ui->m_smsdraft->setModel(m_draftmodel);

    ui->m_smsrecv->setHidden(true);

    ui->m_smssend->setHidden(true);

    ui->m_smsdraft->setHidden(false);

    //ui->m_smsdraft->setShowGrid(true);

     //ui->m_smsdraft->setItem(1,1, m_sendmodel);

    m_draftmodel->clear();

    m_draftmodel->setHorizontalHeaderItem(0, new QStandardItem(tr("At")));

    m_draftmodel->setHorizontalHeaderItem(1, new QStandardItem(tr("Name")));

    m_draftmodel->setHorizontalHeaderItem(2, new QStandardItem(tr("Acount")));

    m_draftmodel->setHorizontalHeaderItem(3, new QStandardItem(tr("Time")));

    m_draftmodel->setItem(1,1, new QStandardItem(tr("Name")));

    ui->m_smsdraft->setColumnWidth(0, 60);

    ui->m_smsdraft->setColumnWidth(1, 80);

    ui->m_smsdraft->setColumnWidth(2, 100);

    ui->m_smsdraft->setColumnWidth(3, 60);
