| ==What does a hierarchy mean?==
| |
| When I look at Mark's diagram, it seems clear to me that we're asking the wrong question. Let's turn the problem around, and look at things from the user standpoint.
| |
| | |
| Take this simple test: Look at a Pipeline Browser representation, and without thinking about (code, etc.) implementation, draw the graph that it represents. Think as a <i>user</i>, not a <i>programmer</i>.

| ===The Test===

| What does this Pipeline Browser representation show? To me, it logically represents [http://www.paraview.org/ParaQ/index.php/Image:Browser_branch_pipeline.png this filter graph. ]

| ===Conclusion===
| |
| In other words, when I look at the Pipeline Browser hierarchy, I think it naturally leads to 'indentation means connection'. If we do it this way, I think we solve several problems - the thing makes sense, and I think it's easy to understand. Of course, this comes at the sacrifice of width - large chains of filters will be 'wide', because we always indent. Remember - we decided not to indent during our design discussion, because we didn't want these things becoming wide.

| | |
| To me, the 'indent means connection' design makes sense, and it makes the whole widget easier to understand. Because of this, I like it for the first rev. We can, through user testing see how long a typical pipeline becomes (how wide they become), and address that problem.
