Is it possible to have multiple header lines in a virtual row tree?

I need some fixed rows for the title of the virtual row view - something similar to the effect you get if you set the property StringGrid

FixedRows

to a value greater than 1. Is there a way to achieve this?

Some searches on the Soft-Gems website and forums have led me to several mentions of method AdvancedHeaderDraw

and property HeaderQueryElements

in the virtual string tree, but I cannot figure out how to use them.

I also found a demo that uses THeaderControls

to achieve a similar effect, but there should be a more elegant solution.

AFAIK nothing like this is built in there. But you could try a VT descendant labeled "Virtual Treeview desc. (Nested titles)" on this page .
