//这就是我所拥有的

        Element root = jTextPane1.getDocument().getDefaultRootElement();

        Element one = root.getElement(0);
        while (one !=null){            
        int one1 = one.getStartOffset();
        int two1 = one.getEndOffset();
        System.out.println(one1);
        System.out.println(two1);
        one = root.getElement(two1);          
     }

这是我得到的(第一个和第二个元素)，然后挂起:01个1个232

This is what I get (1st and 2nd element) and then hangs:011232

推荐答案

您可以混合使用模型和视图. Document只是模型，但行数取决于视图(内容的宽度).

You mix model and view. Document is just model but amount of rows depends on view (width of content).

使用javax.swing.text.Utilities.getRowStart()/getRowEnd()
