Re: [Java-gnome-developer] Re: Tree view Expand row signal

[Manuel L. <man...@co...>]

Adding more comments.

result is a TreeIter.

I'm trying this inside the callback function
if ( obj != null ) {
    TreeIter item = (TreeIter)obj;
    System.out.println("Value : " + _treeStore.getValue(item,
_dataName));
}

But I'm getting a classcast exception.
