Dosao sam do resenja u medjuvremenu, pa ako je nekom potrebno:


Resenje za selekciju:

void __fastcall TForm1::TreeView1MouseDown(TObject *Sender,
      TMouseButton Button, TShiftState Shift, int X, int Y)
{
   if ( Button == mbRight )
   {
      TTreeView *pTreeView = static_cast<TTreeView*>( Sender );
      if ( pTreeView )
      {
          THitTests HT;
          HT = pTreeView->GetHitTestInfoAt( X,Y );
          if ( HT.Contains( htOnItem ) )
             pTreeView->GetNodeAt( X,Y )->Selected = true;
      }
   }        
}

PopUp treba da se postavi u ObjectInspectoru (elegantnije je)
