Hi all,

how about a enhancement of TList?

-------------------------------------------------------
TObject *TList::FindWidget(Int_t id) const
{
 if (id<0)
   return NULL;

 TObject *obj;
 TIter Next(this);
 while ((obj=Next()))
 {
   const TGWidget *wid =
(TGWidget*)obj->IsA()->DynamicCast(TGWidget::Class(), obj);
   if (!wid)
     continue;

   if (id == wid->WidgetId())
     return obj;
 }
 return NULL;
}
--------------------------------------------------------

If you use a TList to order GUI elemets this could sometimes be very
usefull.

Best regards,
Thomas.
