Re: [Openjgraph-development] Adding a mouse listener to a VisualVertex

[Patrick H. <pa...@13...>]

To folow up on this, further debugging has shown that an element is
being added to mouseListeners in AbstractVisualGraphComponent properly.
When processMouseEvent() is called, however, mouseListeners has no
elements.  This leads me to believe that the code below is modifying
the wrong VisualVertex object (i.e., a different object than what is
clicked on in the graph panel).  If that is case, how do I get a
reference to the VisualVertex that is in the VisualGraph so that I can
operate on it?  Thanks.

}     }
} }:
}
