Foi lan\u00e7ado o projeto Cambalache 1.0, que desenvolve uma ferramenta para a cria\u00e7\u00e3o r\u00e1pida de interfaces para GTK 3 e GTK 4, usando design visual (WYSIWYG), a paradigma MVC e a filosofia de prioridade ao modelo de dados. A atribui\u00e7\u00e3o do n\u00famero da vers\u00e3o 1.0 \u00e9 apresentada como uma conquista que demonstra a prontid\u00e3o do projeto para uso generalizado. O c\u00f3digo \u00e9 escrito em Python e \u00e9 disponibilizado sob a licen\u00e7a LGPLv2.1. Um pacote no formato flatpak est\u00e1 dispon\u00edvel para instala\u00e7\u00e3o. <\/p>\n

Diferentemente do Glade, o Cambalache oferece suporte para manter v\u00e1rias interfaces de usu\u00e1rio em um \u00fanico projeto. Cambalache n\u00e3o depende do GtkBuilder e GObject, mas fornece um modelo de dados que corresponde ao sistema de tipos GObject. O suporte para edi\u00e7\u00e3o, visualiza\u00e7\u00e3o e cria\u00e7\u00e3o de estilos GTK em formato CSS, edi\u00e7\u00e3o de arquivos XML com recursos GResources, cria\u00e7\u00e3o de templates e widgets, utiliza\u00e7\u00e3o de arquivos XML do GtkBuilder e a marca\u00e7\u00e3o Blueprint s\u00e3o suportados. <\/p>\n

O modelo de dados pode importar e exportar v\u00e1rios interfaces de uma s\u00f3 vez, suporta objetos, propriedades e sinais do GtkBuilder, oferece uma pilha de opera\u00e7\u00f5es de desfazer\/refazer (Undo\/Redo) e a possibilidade de compress\u00e3o do hist\u00f3rico de comandos. Para a gera\u00e7\u00e3o do modelo de dados a partir de arquivos gir, est\u00e1 dispon\u00edvel a ferramenta cambalache-db, e para a gera\u00e7\u00e3o de classes GObject a partir das tabelas do modelo de dados \u2014 a ferramenta db-codegen. <\/p>\n

A interface pode ser gerada com base no GTK 3 ou GTK 4, dependendo da vers\u00e3o especificada no projeto. Para garantir suporte a diferentes vers\u00f5es do GTK, a forma\u00e7\u00e3o da \u00e1rea de trabalho \u00e9 realizada em um processo separado com a participa\u00e7\u00e3o do widget Casilda, que permite incorporar janelas de outros processos em aplica\u00e7\u00f5es GTK4 e \u00e9 implementado como um compositor especializado servidor<\/a>, utilizando o protocolo Wayland e a biblioteca wlroots. A Casilda cria dispositivos de entrada virtuais, cujos eventos s\u00e3o transmitidos pelo GtkEventController, e tamb\u00e9m um dispositivo de sa\u00edda virtual, com o mesmo tamanho que o widget integrado ao aplicativo. Com o wlroots, o conte\u00fado para visualiza\u00e7\u00e3o \u00e9 renderizado em um buffer de pixels e carregado como uma superf\u00edcie Cairo (cairo.Surface) para renderiza\u00e7\u00e3o no GTK. \"Lan\u00e7amento \"Lan\u00e7amento \"Lan\u00e7amento
