Build Identifier: M20110909-1335 I'm using the Treeviewer like a pivot table in Excel. The parent nodes of a tree are like pivots - column 1 shows a categorization field value and the other columns summarize the values in the children nodes. There can be many different "pivot" levels and it is customizable just like a pivot table in excel. We allow the users to drag and drop nodes of the tree around to arrange the structure of the tree any way they like. If level 1 of the tree is a pivot for "Field A" and the user wants "Field B" to be level 1, he can just drag a node for "Field B" above the node for "Field A" and it does what he wants. What I want to be able to do is what Excel allows you to do for a pivot table. In a pivot table, I can drag a column header over to the "pivot" list and it modifies the structure of the table, now summarizing by the column that just became a pivot. I'd like to be able to drag a Treeviewer Column header and drop it on the first column of the tree to edit the structure of my tree example: Let's say it's financial data and the current tree structure has Sector as a parent and child nodes for each item in each sector sector. So maybe there are parent nodes for Sector A, Sector B, Sector C, etc with child nodes for items in each sector. Now let's say Subsector is a column. Maybe the user wants to add a SubSector node to the tree structure, under the Sector level. Dragging the SubSector column header and dropping it on a Sector node could tell the code to create a SubSector Grouping below the Sector level and refresh the tree structure, now showing the data grouped by both Sector and SubSector. I can't implement this because I'm not seeing how I can drag a TreeColumn and drop it anywhere other than moving it around to reorder the column. Can a future version of Eclipse allow more support for dragging a TreeColumn? Could it be given the same dnd functionality as a TreeItem? If this already exists, I apologize, but I didn't see it.. Thanks Reproducible: Always
clarification: when I said "I'd like to be able to drag a Treeviewer Column header and drop it on the first column of the tree to edit the structure of my tree" I meant I want to drag a TreeColumn header and drop it on a row in the first column.
