# QT Philosophy

QT : Un SDK basé sur C++

Pourquoi choisir QT ?

Pourquoi ne pas choisir QT ?

  • Simple d'utilisation
  • Cross platform
  • Open Source
  • Grande communauté
  • Beaucoup d'outils
  • Rapidité de conception
  • Documentation
  • Exécution lente
  • Complexe pour certaines taches
  • Consommation mémoire importante

# Bindings QT

C'est quoi un Binding ?

En informatique, un "binding" est une interface de programmation d'application (API) qui permet d'executer du Code d'un langage

étranger depuis un autre langage
