Bonjour

dans un QtableWidget, ma colonne 0 est une colonne de case à coché.

Je gère ces case à cochées grace à un delegate (cf ci-dessous)

Jusqu'a présent cela se passé bien. Mais depuis l'arrivé de Yosemite sur mac, l'interface graphique du système a changé, et la case à coché reste sur fond blanc et le tag aussi. Bref c'est illisible. (cf image)

Bref je cherche à changer le style de la case à cochée pour la rendre lisible. Mais je n'y arrive pas. Je ne comprend rien ni au painter ni au style etc...

Pouvez vous m'aider ou me mettre sur la voix?


premiere case coché, pas la deuxième...
