[Plib-users] callbacks2

[Tinoshi K. <ti...@li...>]

I tried to change isA with

  else if ( e -> isAKindOf ( ssgTypeLeaf() ) )
  {
    ssgLeaf* leaf =3D (ssgLeaf *) e ;
    leaf -> setCallback ( SSG_CALLBACK_PREDRAW, setWireframe) ;
  }

but nothing changed... so this is not the problem... well, I think that =
with isA() doesn't work at all...
