Requests | Пожелания / report does not allow change to application

« on: October 24, 2020, 04:10:18 PM »

Good afternoon, A query, when showing the report with previewReport () it does not let me return to my application until I close the report, how can you solve this.



This is the code of my button that shows the report, as I said before, when the report is shown it no longer lets me return to my application, if not until closing the report, any suggestions would be appreciated.

Code: [Select]

void Widget::on_pushButton_2_clicked()
{
  QFile fileName(":/rpt/Reporteusuarios.lrxml");
  if(!fileName.open(QIODevice::ReadOnly|QIODevice::Text)){
      QMessageBox::critical(this,qApp->applicationName(),
                            QString("Error al abrir el reporte.\n").append(
                              fileName.errorString()));
      return;
    }
  mReport=new LimeReport::ReportEngine(this);
  mReport->dataManager()->setReportVariable("DATABASE",db.strConexion());
  mReport->loadFromFile(fileName.fileName());
  mReport->previewReport();

}

well I did not understand that, what happens is that, I use the designer to create the report, and just call it from my app, in my application I get the address of the database with qApp-> applicationDirPath (). append (" /db/dbejemplo.db "), but this as reflected in the report, a practical example would be good, if possible.

Hi guys, I am using this report generator and I managed to design my report and then link it to my form, I managed to show the report from a button, my question is how do I change the path from where I have the database dynamically, that is, to the move the database or when distributing my app to another computer, since I have to be editing the lrxml file, to change the path manually, I am using a SQlite db for now. Thanks, I hope your suggestions.


code of my button where I show the report, I have it added as a resource of my application...

Code: [Select]

void Widget::on_btnReporte_clicked()
{
  QFile reportName(":/reports/ejemplo.lrxml");
  if(!reportName.open(QIODevice::ReadOnly|QIODevice::Text))
    {
      QMessageBox::critical(this,qApp->applicationName(),
                            "Ocurrio un error al cargar el reporte.0\n"+reportName.errorString());
      return;
    }
  _report=new LimeReport::ReportEngine(this);
  _report->loadFromFile(reportName.fileName());
  _report->previewReport();
}



Code: [Select]

<datasourcesManager ClassName="LimeReport::DataSourceManager" Type="Object">
      <objectName Type="QString">datasources</objectName>
      <connections Type="Collection">
        <item ClassName="LimeReport::ConnectionDesc" Type="Object">
          <objectName Type="QString"></objectName>
          <name Type="QString">reporte</name>
          <driver Type="QString">QSQLITE</driver>
          [b]<databaseName Type="QString">D:/QtProjects/BranchExe/db/dbejemplo.db</databaseName>[/b]
          <userName Type="QString"></userName>
          <password Type="QString" Value=""/>
          <host Type="QString"></host>
          <autoconnect Type="bool" Value="1"/>
          <keepDBCredentials Type="bool" Value="1"/>
          <port Type="int" Value="-1"/>
        </item>
      </connections>
This is the part I am referring to, in the databaseName tag, how do I get that path changed, without having to do it manually.
