The EntityTablePanel provides a table view of entities.

1. Adding a print action

The most common place to add a custom control is the table popup menu, i.e. an action for printing reports or for acting on the selected rows. For the simplest case, where a single print action is required, a custom control can be associated with the PRINT ControlKey, this control will appear in the Print submenu in the table popup menu as well as on the table toolbar.

For more complex cases, where multiple print controls are required, custom controls can be associated with the PRINT_CONTROLS ControlKey.

public class CustomerTablePanel extends EntityTablePanel {

  public CustomerTablePanel(SwingEntityTableModel tableModel) {
    super(tableModel);
    // associate a custom Control with the PRINT control key,
    // which calls the viewCustomerReport method in this class,
    // enabled only when the selection is not empty
    control(PRINT).set(Control.builder()
            .command(this::viewCustomerReport)
            .caption("Customer report")
            .smallIcon(FrameworkIcons.instance().print())
            .enabled(tableModel().selection().empty().not())
            .build());
  }

  private void viewCustomerReport() {
    List<Entity> selectedCustomers = tableModel().selection().items().get();
    if (selectedCustomers.isEmpty()) {
      return;
    }

    Collection<String> customerIds = Entity.values(Customer.ID, selectedCustomers);
    Map<String, Object> reportParameters = new HashMap<>();
    reportParameters.put("CUSTOMER_IDS", customerIds);

    JasperPrint customerReport = tableModel().connection()
            .report(Customer.REPORT, reportParameters);

    Dialogs.componentDialog(new JRViewer(customerReport))
            .owner(this)
            .modal(false)
            .title("Customer Report")
            .size(new Dimension(800, 600))
            .show();
  }
}
