Code examples

The following simple examples demonstrate how easy to integrate and use NCReport in any Qt application. The codes are Qt4.6 – Qt5.8 compatible. The project file settings are based on Qt .pro file syntax.

Run report to the preview window 1.

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    NCReport *report = new NCReport();

    report->setReportSource( NCReportSource::File ); // set report source type
    report->setReportFile("myreport.ncr"); //set the report filename fullpath or relative to dir
    report->runReportToPreview(); // run to preview output

    // error handling
    if( report->hasError())
    {
        QMessageBox msgBox;
        msgBox.setText(QObject::tr("Report error: ") + report->lastErrorMsg());
        msgBox.exec();
    }
    else
    {
        // show preview
        NCReportPreviewWindow *pv = new NCReportPreviewWindow();    // create preview window
        pv->setOutput( (NCReportPreviewOutput*)report->output() );  // add output to the window
        pv->setReport(report);
        pv->setWindowModality(Qt::ApplicationModal );    // set modality
        pv->setAttribute( Qt::WA_DeleteOnClose );    // set attrib
        pv->exec();  // run like modal dialog
    }
    delete report;
}Swift

Run report to the preview window 2.

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    NCReport *report = new NCReport();
    report->setReportFile("myreport.ncr"); //set the report filename fullpath or relative to dir
    report->runReportToShowPreview(); // run and show to preview output

    // error handling
    if( report->hasError())
    {
        QMessageBox msgBox;
        msgBox.setText(QObject::tr("Report error: ") + report->lastErrorMsg());
        msgBox.exec();
    }
    delete report;
}Swift

Run report to PDF

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    NCReport *report = new NCReport();
    report->setReportFile("myreport.ncr"); //set the report filename fullpath or relative to dir
    report->runReportToPDF("c:/temp/myreportoutput.pdf")

    // error handling
    if( report->hasError())
    {
        QMessageBox msgBox;
        msgBox.setText(QObject::tr("Report error: ") + report->lastErrorMsg());
        msgBox.exec();
    }
    delete report;
}Swift
