[Code Rom]

Bonjour,

j'ai un petit soucis j'arrive a charger puis afficher mon image de fond, mais elle s'affiche en tout petit, alors qu'elle est bien au dimension de ma fenêtre.

J'aimerais donc qu'elle s'affiche correctement et remplisse bien tout l'arrière plan.

Voici le code, je précise que je découvre gtk4, donc soyez indulgent, merci.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part
