jasper-reports - 如何让 jasper 报告在 JDialog 的顶部？

Question

我使用 Netbeans 的 jasper 报告插件制作报告，我使用 JDialog 中的一个按钮来显示我的 jasper 报告。但是报告显示在我的 JDialog 上，这里有什么问题？

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();
    }
}

我是这样添加 setModal 的:

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();
    }
}

我的报告在 JDialog 上显示为顶部，但其中的按钮不起作用。

您可以使用此代码使 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);
