[SOLVED] How to obtain the row from a mouse click on JEditorPane containg an HTML table

How to obtain the row from a mouse click on JEditorPane containg an HTML table

Is there a way to obtain the row index within an HTML table defined in a JEditorPane? I tried viewToModel method but this isn't what I was expecting.

pane.addMouseListener(new MouseListener(){

    @Override
    public void mouseClicked(MouseEvent e) {
        System.out.println( pane.viewToModel(e.getPoint()) );               
    }

                ...

Solution

Easy/lazy answer: of course you cannot. Even in a pure html page, you need some javascript to achive this. JEditorPane can't handle javascript (i think, maybe i'm wrong), so no chance.

Now, you can use a different approach:

Change a field (or create a new one) with a link.
The link will have as url somenthing like #rowXXX, where XXX is the number of the row.

<a href="#row001">Some field</a>

Add a HyperlinkListener to the jEditorPane:

editor.addHyperlinkListener(new HyperlinkListener() {
            @Override
            public void hyperlinkUpdate(HyperlinkEvent e) {
                if(e.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
                    try {
                        String rowcode = e.getDescription();
                int row = Integer.parseInt(rowcode.replace("#row",""));
                    } catch (IOException ioe) {
                        ioe.printStackTrace();
                    }
                }
            }

        });

Now in row you should have the number of the row.
