Pb Chargement image - AbstractAction
Bonjour,
Malgré mes nombreuses recherche je ne trouve pas d'ou viens le problème du chargement des images sur un toolsbar.
Les chemins d'accès des images sont corrects. Toutefois les attributs "width" et "heigth" de l'image sont à 0.
voici le code (TestActions.java):
