TTMSFNCTableView click on accessory show detailcontrol

Its possible when click on Accessory to show the DetailControl associated with item ?

You can do this with the following code:

procedure TForm1.TMSFNCTableView1ItemAccessoryClick(Sender: TObject;
  AItem: TTMSFNCTableViewItem);

why its so slow ? there is a way to show fast without animation ?

Yes, this is possible if you set the AnimationFactor to 0:

TMSFNCTableView1.Interaction.AnimationFactor := 0;

yes go better but i think Detailcontrol panel (with not many components inside) is very too slow than using a separate form. There is any way to "fast" it ?
