Why this code don't work?

int numItems = 300;
    QStandardItemModel * queryModel = new QStandardItemModel(numItems , 1);
 
    for (int row=0; row<numItems; ++row) {
        QStandardItem *item = new QStandardItem(QString("row %0").arg(row));
        queryModel->setItem(row, 0, item);
    }
     QComboBox *combo = new QComboBox;
     combo->setModel(queryModel);
     combo->view()->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded);
    // MaxVisibleItems set
     combo->setMaxVisibleItems(20);//why this don't work
     combo->show();

int numItems = 300;
    QStandardItemModel * queryModel = new QStandardItemModel(numItems , 1);

    for (int row=0; row<numItems; ++row) {
        QStandardItem *item = new QStandardItem(QString("row %0").arg(row));
        queryModel->setItem(row, 0, item);
    }
     QComboBox *combo = new QComboBox;

Does the following apply to your system?

This property is ignored for non-editable comboboxes in styles that returns false for QStyle::SH_ComboBox_Popup
