Virtual TreeView i jego wygląd

Mam kilka pytań związanych z tym komponentem, może ktoś kto jest już obcykany z nim zechciałby napisać jak uzyskać takie coś:
Obrazek 1 (chodzi mi tutaj o ten zaznaczony element, a konkretnie: grafika w nim, kilka linijek tekstu)

Obrazek 2 tutaj także chodzi o zaznaczony element - o jego tło.

Również przy okazji chciałem zapytać czy da się w tym komponencie sprawić by wybrana gałąź drzewa miała taką właściwość jak niektóre komponenty, czyli Enabled. To znaczy żeby nie dało się jej rozwinąć kliknąć itp.

1 i 2 - trzeba sobie narysować samemu, niestety
a) inna szerokość zaznaczonego - w OnMeasureItem
if Node = vt1.GetFirstSelected then
NodeHeight := 50
else
NodeHeight := 18;

do rysowania masz do wyboru do koloru
