How to set QTableView data to the limereport file lrxml
« on: June 07, 2024, 09:37:16 AM »
I want to set QTableView data to Lime report, I tried with this code void MainWindow::loadJsonData()
{
    QFile file(":/data/sample.json");
    if (!file.open(QIODevice::ReadOnly))
    {
        qWarning("Couldn't open the file.");
        return;
    }

    QByteArray data = file.readAll();
    QJsonDocument document = QJsonDocument::fromJson(data);
    QJsonArray jsonArray = document.array();

    model->setColumnCount(3);
    model->setHeaderData(0, Qt::Horizontal, "Name");
    model->setHeaderData(1, Qt::Horizontal, "Age");
    model->setHeaderData(2, Qt::Horizontal, "City");

    for (const QJsonValue & value : jsonArray)
    {
        QJsonObject obj = value.toObject();
        QList<QStandardItem *> items;
        items.append(new QStandardItem(obj["name"].toString()));
        items.append(new QStandardItem(QString::number(obj["age"].toInt())));
        items.append(new QStandardItem(obj["city"].toString()));
        model->appendRow(items);
    }
}

void MainWindow::on_generateReportButton_clicked()
{
    report->loadFromFile(":/reports/sample_report.lrxml");
    report->dataManager()->addModel("jsonData", model, true);
    report->previewReport();
}
but I don't know how to handle with limereport designer,

Hi!

QTableView dot't store any data it's own.
The data exists in the model.
This model You have been added to report.

Now You can just call
Code: [Select]
report->designReport() to show LRDesigner, and your model must be shown in datasources

Subst, thank you, I tried and succeeded , I saw the model in the data sources panel, and When I tried with columns, it shows only the first item of the model, how can I achieve this to show all items which I set with qt created app.

Hi. You have to set datasource property on the databand that will point to the data source
