How to prevent parent frame closed when closing child frame (Java + iReport)?

问题

Basically I want to call JasperViewer from a button on my Main Application. I use this

private void btnExportActionPerformed(java.awt.event.ActionEvent evt) {
        try {
            JasperPrint printer = JasperFillManager.fillReport(getClass().getResourceAsStream("reportRecharge.jasper"), params, new JREmptyDataSource());
            JasperViewer jv = new JasperViewer(printer);
            jv.setVisible(true);
        } catch (JRException ex) {
            ex.printStackTrace();
        }
}

When a JasperViewer appear and I close it, the main frame / parent also closed. I've try adding jv.setDefaultCloseOperation(HIDE_ON_CLOSE); but it's not working either. How to get it?

Any help would be appreciated.

回答1:

change like below. if you add false the default exit on close property becomes false.

private void btnExportActionPerformed(java.awt.event.ActionEvent evt) {
        try {
            JasperPrint printer = JasperFillManager.fillReport(getClass().getResourceAsStream("reportRecharge.jasper"), params, new JREmptyDataSource());
            JasperViewer jv = new JasperViewer(printer,false);
            jv.setVisible(true);
        } catch (JRException ex) {
            ex.printStackTrace();
        }
}
