Okay ich habs schon, sorry für den Thread...
Lösung:
Delphi-Quellcode:
procedure TMainForm.TreeView1DragDrop(Sender, Source: TObject; X, Y: Integer);
var
i : Integer;
begin
for i := 0 to (Source as TListBox).SelCount - 1 do
MyTreeNode2 := TreeView1.Items.Add(MyTreeNode1,(Source as TListBox).Items.Strings[i]);
end;
procedure TMainForm.TreeView1DragOver(Sender, Source: TObject; X, Y: Integer;
State: TDragState; var Accept: Boolean);
begin
Accept := True;
end;
Thema kann geschlossen werden.
