// ------- Pb de gestion du focus-keyboard  Motif-PIBaseWdg -------
// ** Note du 26/02/98 - Reza 
// Je desactive pour le moment XmNnavigationType et XmNtraversalOn
// afin d'ameliorer la gestion du focus-keyboard entre Widget Motif
// et objet Peida - Cela semble avoir un effet secondaire - 
// Il faut que la souris reste dans le widget Text pour taper dedans
// ** Note du 30/04/98 - Reza
// J'ai modifie le mecanisme de gestion des evenements pour PIBaseWdg
// en passant par un EventHandler - Le probleme de gestion du 
// focus-keyboard n'a pour autant pas ete resolu
// Je reactive XmNtraversalOn pour les PIText - Le probleme 
// d'attribution du focus-keyboard au PIBaseWdg reste si on 
// met PIText et un PIBaseWdg ds un meme conteneur
