javahtmlswingjtextpanesoft-hyphen

Using ­ in Java HTML aware Component

I have following problem:

I display an HTML-Document with an JTextPane.

In my HTML-Text there are ­ (shy at w3.org) to make a soft-hyphenation. My problem is, that no hyphenation appears. Is there some kind of flag, which I don't know, to use these option?

Following Programm will show the problem:

package com.dvelop.ckue.swing;

import javax.swing.*;
import javax.swing.text.html.HTMLEditorKit;
import java.awt.*;

public class SwingGui extends JFrame {

    public static void main(String[] args) {
        SwingGui sg = new SwingGui();
        sg.setSize(new Dimension(200, 800));
        sg.setPreferredSize(new Dimension(200, 800));
        sg.pack();
        sg.setVisible(true);
        sg.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    private SwingGui() {
        super();
        setLayout(new FlowLayout());

        // No "-" appears, but a linebreak
        add(createField("<html>longlong<br>longlong<br>longlonglonglonglonglonglonglonglonglongWord"));
        // No linebreak, but the hyphenationsymbol
        add(createField("<html>longlong&shy;longlong&shy;longlonglonglonglonglonglonglonglonglongWord"));
        // Linebreak, but not where expected and no symbol            
        add(createField("<html>longlong&#8203;longlong&#8203;longlonglonglonglonglonglonglonglonglongWord"));
        // No linebreak, no symbol
        add(createField("<html>longlonglonglonglonglonglonglonglonglonglonglonglonglongWord"));
    }

    private JTextPane createField(String content) {
        JTextPane field1 = new JTextPane();
        field1.setPreferredSize(new Dimension(100, 200));
        field1.setAutoscrolls(true);
        field1.setEditorKit(new HTMLEditorKit());
        field1.setText(content);
        return field1;
    }

}

My expected behavior is, that my text will be broken to the next line:

longlong- 
longlong-
longlonglonglongWord

As seem by the first block, but with an hyphenation-sign.

EDIT: It will work in most browsers, but I don't use a webbrowser here.

EDIT 2: I use a JTextPane, I don't know, if Java will use some installes HTML rendering-engine internally.

Solution

  • http://java-sl.com/Hyphenation_In_JEditorPane.html That's an example of custom hyphnation. You can use the same approach and change the HTMLEditorKit to use your hyphens.
