Listbox Einträge verschieben

[ebber]

Ja genau sowas habe ich gesucht. Danke.

Ich habe hier noch diesen Code gefunden. Mit ihm kann man auch zwischen 2 Listboxen hin und her schieben.

Delphi-Quellcode:

procedure TForm1.ListBox1DragDrop(Sender, Source: TObject; X, Y: Integer);
var
  iTemp: Integer;
  ptTemp: TPoint;
  szTemp: string;
begin
  { change the x,y coordinates into a TPoint record }
  ptTemp.x := x;
  ptTemp.y := y;

  { Use a while loop instead of a for loop due to items possible being removed
   from listboxes this prevents an out of bounds exception }
  iTemp := 0;
   while iTemp <= TListBox(Source).Items.Count-1 do
  begin
    { look for the selected items as these are the ones we wish to move }
    if TListBox(Source).selected[iTemp] then
    begin
      { use a with as to make code easier to read }
      with Sender as TListBox do
      begin
      { need to use a temporary variable as when the item is deleted the
        indexing will change }
        szTemp := TListBox(Source).Items[iTemp];

        { delete the item that is being dragged  }
        TListBox(Source).Items.Delete(iTemp);

      { insert the item into the correct position in the listbox that it
       was dropped on }
        Items.Insert(itemAtPos(ptTemp, True), szTemp);
      end;
    end;
    Inc(iTemp);
  end;
end;

procedure TForm1.ListBox1DragOver(Sender, Source: TObject; X, Y: Integer;
  State: TDragState; var Accept: Boolean);
begin
 Accept := Sender is TListBox;
end;

Wäre es möglich in das auch das einzufügen ?

Zitat von bitsetter:

Hi,

Delphi-Quellcode:

procedure TForm1.ListBox1DragOver(Sender, Source: TObject; X, Y: Integer;
  State: TDragState; var Accept: Boolean);
begin
 if source is TListbox then
 begin
   accept:= true;
   ListBox1.Items.Move(ListBox1.ItemIndex,ListBox1.ItemAtPos(point(x,y),true));
   ListBox1.ItemIndex:= ListBox1.ItemAtPos(point(x,y),true);
 end
 else
    accept:= false;
end;
