如何使Jasper报告成为JDialog的顶部

Question

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 {
        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");
        setModal(false);
        jasperViewer.setVisible(true);
        setModal(true);
    } catch (SQLException | JRException e){
        e.printStackTrace();
    }
}

我的报告显示在JDialog的顶部，但其中没有按钮起作用。请解决！

您可以使用以下代码使JR显示为JDialog：

//after creating jasperViewer//
jasperViewer = new JasperViewer(jasperPrint, false);
JDialog dialog = new JDialog(this);//the owner
dialog.setContentPane(jasperViewer.getContentPane());
dialog.setSize(jasperViewer.getSize());
dialog.setTitle("XXXXX");
dialog.setIconImage(Toolkit.getDefaultToolkit().getImage(
getClass().getResource("URL IMG")));
dialog.setVisible(true);
