Do you want to know, how TCustomTreeView.DoPaintNode works, or why it
works this way?
The font color is overriden by DoPaintNode in both cases.
I think, that the OnCustomDrawItem is not very useful at the
moment, because it has to paint the whole line, with tree lines, icons
and text. Maybe Borland thought the same and that's why they added the
Advanced event. I didn't check how compatible OnCustomDrawItem is.
