Default RE: Printing TTreeView on Quick Report

Printing a TTreeView in not something trivial. It can be made of thousand of nodes, each of which possibly having thousand of subnodes, and so on.

What I would recomand is to limit the number of levels to an arbitrary number, let's say 10, so the report width fits into a page. Then, use a Memory Dataset (A good one comes with DevExpress's Quantum Grid but there are some that you can download here and there). This dataset can be comprised of only one Text Field that will content the Node Text property but you may add other fields as well (a Blob field could contain the node bitmap).

While you browse thru each node of the TTreeView, grap the Text property of the Node and use the Level property to add some spaces in front of the Text. So a Level 0 node will have its text stored as "Some Text", a Level 1 node will be " Some Text", a Level 2 node will be " Some Text" and so on.

All there is left to do is to connect the QuickReport to your dataset.
