Model browser ala MacOSX' finder [message #687512] Fri, 17 June 2011 07:26

I've needed to browse some large modisco-based models lately and have
found the standard Ecore editor to be difficult to use. The model is
large and there are cross-resource links that require lots of scrolling
up and down to view all relevant parts for some task. It would be better
to have an editor with several panes that support drill-down in separate
parts of a resource set's content.

Now I've prototyped an editor that's a hybrid between a tree and MacOSX'
finder design. The editor is a sash form (split pane) with 4 panes, each
of which has an input selector and a normal tree viewer. In the default
case, a tree viewer is linked to its left neighbor's selection, so what
you select in one tree becomes the (invisible) root node of the next.
Hence, you can drill down by either expanding a node in a tree or by
selecting the node and tabbing to the next tree. If you want to view
different parts of a model, you may instead select a resource as the
tree's root.

The attached screenshot shows the editor in action. The first and third
show different resources, while the second and fourth follow the other
two's selections.

If this design seems useful, I can make it available on GitHub.
