iReport - 如何将报告方向更改为RTL？

Question

如何在iReport中将页面方向更改为RTL，因为正在处理应以英语和英语显示的报告。阿拉伯语，我使用本地文本出现在两种语言，但我找不到任何改变方向

我知道之前曾问过这个问题，但我没有找到任何答案：How to make a report page direction to change to "rtl"?

Answer 1

据我搜索没有属性，你可以使用下面的util class：

package foo.bar.utils.export;

import java.util.Iterator;
import java.util.List;

import net.sf.jasperreports.engine.JRPrintElement;
import net.sf.jasperreports.engine.JRPrintFrame;
import net.sf.jasperreports.engine.JRPrintPage;
import net.sf.jasperreports.engine.JasperPrint;

    /**

    public static void mirrorLayout(JasperPrint print) {
        int pageWidth = print.getPageWidth();
        for (Object element : print.getPages()) {
            JRPrintPage page = (JRPrintPage) element;
            mirrorLayout(page.getElements(), pageWidth);
        }
    }

    /**
     * mirror a list of elements
     * @param print
     */
    protected static void mirrorLayout(List<?> elements, int totalWidth) {
        for (Iterator<?> it = elements.iterator(); it.hasNext();) {
            JRPrintElement element = (JRPrintElement) it.next();
            int mirrorX = totalWidth - element.getX() - element.getWidth();
            element.setX(mirrorX);

            if (element instanceof JRPrintFrame) {
                JRPrintFrame frame = (JRPrintFrame) element;
                mirrorLayout(frame.getElements(), frame.getWidth());
            }
        }
    }
}
