Создать редактируемый TListBox

{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;
