WinDirStat-like control in Delphi

The program WinDirStats (written in C++, see http://sourceforge开发者_如何学运维.net/projects/windirstat/ ) has at the top a control that combines a tree-like structure (The column "Name", first on the left) with other types of data (graphic bar in column "Subtree percentage") and other text columns.

My question is, using Delphi 7, which control should I use to do something like that? It's the tree part that I find more difficult to get right.

The best control for this would most likely be Mike Lischkes Virtual Tree View.

• It's free
• It gives you a tree connected with a list view
• It allows for custom drawing
• It's incredibly flexible
• It's lightning fast

The only downside is that you have to learn a quite different paradigm than most Delphi controls have, but apart from that it is a teriffic control.

I myself have used it in various projects quite successfully and never hit a real roadblock while using it.

I also prefer Virtual Treeview, but here are some commercial alternatives:

• ExpressQuantumTreeList
• ElTree
• TTreeList
