|Re: [nebula-dev] Using tree capabilites from XViewer|
Not sure I understand the question. Each object represents a row, not column, and the content provider provides the child/parent relationships of the modely by answering the hasChildren and getChildren questions. It's up to the model and the code that creates it to come up with the relationships and provide those to the treeviewer.
Maybe you can point to an example of what you mean by chaining model objects together.

Subject: [nebula-dev] Using tree capabilites from XViewer
I am playing with the example and couldn’t find a way to group columns to build a tree view? There is a picture of a XViewer with tree/table view on the Nebula XViewer Web page. I guess my questions are; 1) Is there a way to dynamically build a tree view in the table by selecting model objects (columns) and connecting them together? If so, is there an example of that in the example code? If not, can it be done in XViewer without having to write custom TreeViewer code to support every possible combination of model relationships the user may choose? There are several examples from other products out there that allow you to chain model objects together and create a tree/table based on the relationships of the objects as defined in the model. Anyone played very extensively with the tree part of the XViewer?
