TListView has OnDrawItem event and property OwnerDraw.
(But I never tried this with ListView)
Lazarus 2.1.0 r64044 FPC 3.3.1 r40507 x86_64-linux-qt Chakra, Qt 4.8.7/5.13.2, Plasma 5.17.3
Lazarus 1.8.2 r57369 FPC 3.0.4 i386-win32-win32/win64 Wine 3.21

Try Eye-Candy Controls: https://sourceforge.net/projects/eccontrols/files/

Maybe, no.

But you can get some help handling events

OnDrawItem*

and property

TextSizeDecored

and text item formated as:    MyTextLeft(my|center|text)MayTextRight

I:=trunc(x/3/D ) *D;

Jcanvas1.drawtext('juan carlos',50,0-tag+i);
Jcanvas1.drawtext('pedro',50,x*1-tag+i);
Jcanvas1.drawtext('carlos,50,x*2-tag+i);
