bonjour,

je suis nouveau sur le forum, et je débute en python avec GTK.

voila mon probleme :

j'ai fait un petit programme pour tracer un carre de couleur dans une fenetre, mais je n'arrive pas à changer la couleur des points traces

je n'ai surement pas tout compris dans l'utilisation des contextes graphiques.

merci de votre aide
