La biblioth\u00e8que GUI Cosmoe a \u00e9t\u00e9 pr\u00e9sent\u00e9e, prenant en charge le fonctionnement sous Linux dans des environnements bas\u00e9s sur Wayland. Cosmoe permet de cr\u00e9er des programmes avec une interface graphique en C++, en utilisant une API inspir\u00e9e de la biblioth\u00e8que de classes du syst\u00e8me d'exploitation BeOS. La biblioth\u00e8que permet de lancer directement dans Linux des programmes utilisant l'API BeOS. Le code du projet est distribu\u00e9 sous la licence MIT. <\/p>\n

Cosmoe propose un ensemble de classes C++ qui facilitent et acc\u00e9l\u00e8rent la cr\u00e9ation d'interfaces utilisateur. D'une part, Cosmoe est nettement plus simple et compact que des kits comme GTK et Qt, mais d'autre part, il permet de cr\u00e9er des interfaces d'apparence plus moderne que lors de l'utilisation de biblioth\u00e8ques l\u00e9g\u00e8res comme FLTK et Xforms. Sur les syst\u00e8mes obsol\u00e8tes, Cosmoe permet d'atteindre une tr\u00e8s faible consommation de ressources, tandis que sur les syst\u00e8mes modernes, il optimise les performances mat\u00e9rielles gr\u00e2ce \u00e0 une utilisation intensive du multithreading. Une collection d'exemples d'applications utilisant Cosmoe pour cr\u00e9er des interfaces est fournie, parmi lesquelles un \u00e9mulateur de terminal, un \u00e9diteur de styles et des jeux simples. <\/p>\n

La biblioth\u00e8que est fond\u00e9e comme un d\u00e9riv\u00e9 l\u00e9ger et sans composants serveur (app_server, registrar) de la base de code du projet Cosmoe Classic, adapt\u00e9e pour fonctionner au-dessus de compilations utilisant le protocole Wayland. Le projet Cosmoe Classic visait \u00e0 porter l'environnement Haiku OS pour fonctionner au-dessus du noyau Linux et utilisait le rendu de l'interface dans une fen\u00eatre cr\u00e9\u00e9e \u00e0 l'aide de la biblioth\u00e8que SDL. Le d\u00e9veloppement de Cosmoe Classic a \u00e9t\u00e9 relanc\u00e9 l'ann\u00e9e derni\u00e8re apr\u00e8s une pause de dix-sept ans. serveurs<\/a>Actuellement, le projet est r\u00e9orient\u00e9, passant du d\u00e9veloppement d'un fork du syst\u00e8me d'exploitation Haiku \u00e0 la cr\u00e9ation d'une biblioth\u00e8que autonome pour la cr\u00e9ation d'applications graphiques sous Linux. \u00c0 ce stade, le d\u00e9veloppement est en phase alpha, et la biblioth\u00e8que prend d\u00e9j\u00e0 en charge environ 95 % des capacit\u00e9s de l'API BeOS. Parmi les restrictions les plus importantes, on note l'absence de prise en charge des instances non li\u00e9es \u00e0 l'\u00e9cran de type BBitmap, n\u00e9cessaires pour l'acc\u00e9l\u00e9ration mat\u00e9rielle du rendu, et l'API BFilePanel, qui cr\u00e9e des dialogues pour l'ouverture et la sauvegarde de fichiers, n'est pas pr\u00eate. <\/p>\n

La biblioth\u00e8que GUI Cosmoe a \u00e9t\u00e9 pr\u00e9sent\u00e9e, prenant en charge le fonctionnement sous Linux dans des environnements bas\u00e9s sur Wayland.
