Click on picture inside JEditorPane

Hi all,

I have a JEditorPane which displays some HTML document with a picture, using an img tag with just a source parameter with something like file:///path/to/my/picture.jpg as its value.

Now when I click inside the JEditorPane with my right mouse button, a mouse listener picks this up, which in turn has a pop up menu pop up. But now I want the pop up menu to have some extra options when I click on the picture.

My question is therefore: is there some way for me to find out if either the picture has been clicked, or the text around it?

Thanks for any help!

don't trust me. you will probably get a better answer later. but unless the image is always in the same place, i don't think you can.

Diederick,
I'm not sure if this is will resolve your problem, but are you familiar with method getDeepestComponentAt in class javax.swing.SwingUtilities ?

Good Luck,
Avi.

I don't think getDeepestComponent will help as the image most likely is not a separate component.

Your JEditorPane has a StyledDocument which should be able to return you the image only using getCharacterElement. Now all you need to do is translate the mouse click into a position. That sounds easier than it is though, as I haven't found a way to do this yet.

Edit: and I may have found it. JTextComponent has method viewToModel that can convert a Point to an offset.
