How do I obtain an Object of a particular ROW in TreeViewer [message #673669]

Hi,

(In short)
In Content provider, we provide all the list of Objects and then the label provider displays them as usual.

Now, I want to click on a particular row's cell (which would have a button widget) and then I need to retrieve the "Object element" used for THAT row.

How do I do it...?? Confused

The reason being that I wish to perform operations on that Object subsequently thereby modifying the model and then call the update() method of the TreeViewer to reflect the model change back in the tree.

Any ideas?
Thx.

ex) IStructuredSelection selected = (IStructuredSelection )viewer.getSelection();
if( selected.isEmpty() == true )
return;
Object obj = selected.getFirstElement();// you can get ,of course , first selected object.

Iterator it = selected.iterates() ;

while( it.hasNext() )
{
Object objIterated = it.next();//you can get all of Object you selected;
}

//////////////////////////////////// OR ///////////////////////////

TableItem[] items = viewer.getTable().getItems();

for( TableItem item : items )
{
Object obj = (Object)items.getData();
}
