我使用Netbeans的jasper报表插件制作报表，我使用JDialog中的按钮显示我的jasper报表。但是该报告又显示在我的JDialog上，这是什么问题？

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                                
    // TODO add your handling code here:
    Map<String, Object> params = new HashMap <>();
    try {
        Connection kon = DriverManager.getConnection(database,user,pass);
        JasperDesign jasperDesign = JRXmlLoader.load("Myreports.jrxml");
        JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, kon);
        JasperViewer jasperViewer = new JasperViewer(jasperPrint, false); 
        jasperViewer.setTitle("My Reports");
        jasperViewer.setVisible(true);
    } catch (SQLException | JRException e){
        e.printStackTrace();
    }
}

我像这样添加setModal：

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                                
    // TODO add your handling code here:
    Map<String, Object> params = new HashMap <>();
    try { …
