Re: Listbox editierbar machen

  Alt 8. Sep 2003, 18:53
Probier das mal so:
Delphi-Quellcode:
{NOTE : This will also work with an OwnerDraw ListBox
But be sure you "pad" the Left Property of the Edit so
Any icons etc, do not get covered up by the TEdit.
And also be aware that there will be a bit of "flashing"
if you do use an OwnerDraw ListBox}
 

{This is in a Popup menu.} 
procedure TForm1.Change1Click(Sender: TObject);
var
  I9: Integer;
  ColInt: Integer;
  LRect: TRect;
begin
  LRect := ListBox1.ItemRect(ListBox1.ItemIndex);
  {Set the size of the TEdit} 
  Edit1.Top := LRect.Top + 1;
  Edit1.Left := LRect.Left + 1;
  Edit1.Width := ListBox1.Canvas.TextWidth(ListBox1.Items.Strings[ListBox1.ItemIndex]) + 6;
  Edit1.Height := (LRect.Bottom - LRect.Top) + 1;

  Edit1.Text := ListBox1.Items.Strings[ListBox1.ItemIndex];
  ListBox1.Selected[ListBox1.ItemIndex] := False;
  Edit1.Visible := True;
  Edit1.SelectAll;
  Edit1.SetFocus;
end;

procedure TForm1.ListBox1Click(Sender: TObject);
begin
  Edit1.Visible := False;
end;

procedure TForm1.Edit1KeyPress(Sender: TObject; var Key: Char);
var
  I8: Integer;
begin
  if Key = #13 then
  begin
    I8 := ListBox1.ItemIndex;
    ListBox1.Items.Delete(ListBox1.ItemIndex);
    ListBox1.Items.Insert(I8, Edit1.Text);
    Edit1.Visible := False;
    Key := #0;
  end;
end;
