在JTable之前和之后附加要打印的文本 [英] Append text for printing before and after a JTable

问题描述

我正在尝试打印 JTable 而 print（）方法效果很好，直到我来到这个场景。让我说我想打印之前，只在第一页（不是标题）文本报告，最后文本这是报告的结束。我想再一次澄清我不需要页眉或页脚，只有当我打印它们时，这个文本出现在最后一页的第一页和最后一页的顶部。

I am trying to print a JTable and the print() method works great till I come to this scenario. Lets say I want to print before, in the first page only (not header) the text "Report" and on the end the text "This is the end of report". I would like once more to clarify that I don't need a header or footer only this text to appear in the top of the first and bottom of the last page when I print them.

我该怎么做？

推荐答案

一种方法是追加（ ）一系列合适的 Printable 实例到 java.awt.print.Book ，如图所示这里。

One way to do this is to append() a series of suitable Printable instances to a java.awt.print.Book, as shown here.

附录： JTable 有 getPrintable（） 应简化事物的方法;这是一个大纲和简单标题可打印：

PrinterJob pj = PrinterJob.getPrinterJob();
Book book = new Book();
book.append(new Title(), pj.defaultPage());
book.append(table.getPrintable(...), pj.defaultPage());
book.append(new EndPage(), pj.defaultPage());
pj.setPageable(book);
pj.print();
...
private static class Title implements Printable {

    Font font = new Font("SansSerif", Font.PLAIN, 48);

    @Override
    public int print(Graphics g, PageFormat pf, int pageIndex)
        throws PrinterException {
        Graphics2D g2d = (Graphics2D) g;
        g2d.translate(pf.getImageableX(), pf.getImageableY());
        g2d.setFont(font);
        g2d.setColor(Color.black);
        g2d.drawString("Report", 50, 200);
        return Printable.PAGE_EXISTS;
    }
}
