[news.eclipse.tools] Re: inserting TreeItems in a tree

[evansac@xxxxxxxxxxx (Alun)]

Piyush,

You need the TreeItem constructor that takes a TreeItem as parent 
and allows you to indicate the position (or index) of the new item,
where the first child of a parent is at index 0.

So, in your case you'd do something like this:

TreeItem newItem = new TreeItem(root, style, 1);

Cheers,

Alun
