Are you sure that you did not turn off TreeOptions.PaintOptions.toShowButtons? Note in this context: there are related properties "ButtonStyle" and "ButtonFillMode".

What is your OS, Laz/FPC version? Where do you have the VirtualTreeView package from?

VTV5 laz port simply doesn't have the icon in touseexplorertheme. Well the the selection theme also doesn't work. It's very simple to fix if you look at virtualtrees.pas. At least for Windows.
