Application GTK simple

Bonjour

Pour des raisons bassement technique j'ai fait le choix de migrer sur LINUX. Avant je codait du JAVA en pro et FREEBASIC pour le plaisir. En migrant sur LINUX plus de WINAPI, et donc DIRECTION GTK. En ce moment je me suis mis en tete de realiser une appli simple avec une barre d'outils (4), ou chaque outil permet de basculer entre 4 groupes de composants.

je cherche donc un tuto qui explique comment creer dans une fenetre la chose.

hello

je ne pense pas que tu trouveras directement un tuto qui te mache le travail.

Cela étant je te suggère de te baser sur une trame telle que la suivante :

1 utiliser une base d'appli genre gtkapplication. tu as dans gtk3-demo d'excellent exemple c'est fourni avec gtk+

2 ensuite il te faut choisir un mode d'affichage des outils

premiere option des icones
