Question

I’m working on a plugin and there’s a view which has a treeviewer.
I want to add nodes to that tree diagrammatically as these nodes are not children for input object (treeviewer.setInput(input object)

example:

I have x and y objects, and they are unrelated
x has child object x1 and child object x2

if I set the input for the tree viewer to x so i’ll get x1 and x2 in my tree as they’re its children

now, How can I add object y to this tree as a tree node while it has no relation with x

Thanks

You can have multiple root objects in a TreeViewer. You can get this by

• using the ArrayContentProvider as the content provider of the tree
• having the root objects of the tree as a array or List
