JTabbedPane insérer une icone sur l'onglet

**mouss4rs** · 23/02/2008, 18h31

bonjour a tous,

j'aimerai inserer une icone sur le premier ongletet le probleme c'est que il ne trouve pas l'image.
c'est une image en .png et j'aimerai savoir si c'est le format qu'il n'accepte pas car il me balance l'erreur du test de ma methode createImage(String path) :

couldn't find file: "+path

Voila ce que j'ai fait :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part
