TreeView mit Anzahl der Datensätze im Text

[omata]

Das sollte so eigentlich gehen...

Delphi-Quellcode:

function DeleteCount(Text:string):string;
var Posi:integer;
begin
  Result:=Text;
  repeat
    Posi:=pos(' (', Text);
    if Posi > 0 then
      delete(Text, 1, Posi);
  until Posi = 0;
  delete(Result, length(Result) - length(Text), length(Result));
end;

function addChildCount(Node:TTreeNode):integer;
begin
  Result:=0;
  if assigned(Node) then begin
    repeat
      if Node.HasChildren then
        Node.Text:=DeleteCount(Node.Text) + ' (' + inttostr(addChildCount(Node.getFirstChild)) + ')';
      inc(Result);
      Node:=Node.getNextSibling;
    until not assigned(Node);
  end;
end;

Aufruf:
addChildCount(TreeView.Items.GetFirstNode);
