JAVA : JEditorPane - Possible to intercept mouseclicks on HTML tags?

Hi,

I'm using a JEditorPane to display HTML pages. I'm familiar with the HyperLinkUpdate listener to intercept mouse clicks on HTML links within a page, but I would like to intercept mouse clicks that land on HTML tags such as a table cell or an item in an ordered list.

1. Can I do this with a JEditorPane ?
2. If so, is it possible to determine which tag within the page has been clicked ?
3. Can I then modify the HTML tag e.g. it's border colour ?

Many thanks

 

The documentation for JEditorPane doesn't say much. Try installing a MouseListener (at the java.awt.Component level) and see if you get ANY events for clicks with System.out's. My guess is that they're intercepted by the JEditorPane and processed in a way that prevents you from dealing with them.

 

Take a look at HTMLEditorKit sources. In public void actionPerformed(ActionEvent e) method you can find the next code:

		Object href = getAttrValue(attr, HTML.Attribute.HREF);
		if (href != null) {
		    if (currentOffset >= currentElement.getStartOffset() &&
			currentOffset <= currentElement.getEndOffset()) {
			
			activateLink((String)href, doc, editor, currentOffset);
			return;
		    }

Code (markup):

activateLink((String)href, doc, editor, currentOffset) fires HyperlinkEvent for all HyperlinkListener objects.

I think that you can implement custom HTMLEditorKit and add support of necessary events for your project. Also it has sense to create custom class for JEditorPane.
