O Qt 6.12 oferece suporte \u00e0s plataformas Windows 10+, macOS 13+, Linux (Ubuntu 22.04\/24.04, openSUSE 16, SUSE 15 SP6, RHEL 9.6\/10.0, Debian 11.6\/12), iOS 17+, Android 9+ (API 23+), webOS, WebAssembly, INTEGRITY, VxWorks, FreeRTOS e QNX. O c\u00f3digo-fonte dos componentes Qt \u00e9 fornecido sob as licen\u00e7as LGPLv3 e GPLv2.     <\/p>\n<p>Qt 6.12 recebeu o status de lan\u00e7amento LTS, para o qual atualiza\u00e7\u00f5es ser\u00e3o geradas ao longo de cinco anos para detentores de licen\u00e7as comerciais. Para usu\u00e1rios n\u00e3o comerciais, o tempo de suporte ser\u00e1 de seis meses (at\u00e9 a forma\u00e7\u00e3o de um novo lan\u00e7amento significativo). O suporte para a antiga linha LTS Qt 6.8 continuar\u00e1 at\u00e9 outubro de 2029, enquanto o suporte para a linha LTS anterior, Qt 6.5, foi encerrado este ano.    <\/p>\n<p>Principais mudan\u00e7as no Qt 6.12:  <\/p>\n<ul>\n<li class=\"l\"> O m\u00f3dulo Qt Canvas Painter foi reconhecido como pronto para uso geral, oferecendo uma API para renderiza\u00e7\u00e3o acelerada por hardware de conte\u00fado 2D e utilizando shaders para criar efeitos visuais complexos. A renderiza\u00e7\u00e3o \u00e9 realizada por meio do motor RHI (Rendering Hardware Interface), que suporta v\u00e1rias APIs 3D (OpenGL, Vulkan, Metal e Direct 3D). Em cima do Canvas Painter, foi implementado um elemento experimental Canvas2D, criado tendo em mente a especifica\u00e7\u00e3o HTML Canvas 2D Context e simplificando o uso de JavaScript para desenhar formas.      <center><img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/10\/b130355f4d5e4c516d003a11e19eac36.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> Um m\u00f3dulo experimental StyleKit foi adicionado, que separa claramente a estrutura dos componentes da interface do usu\u00e1rio e os atributos de estilo, permitindo eliminar a duplica\u00e7\u00e3o de c\u00f3digo ao implementar temas claros, escuros e de alto contraste. O StyleKit oferece uma API QML \u00fanica para descrever estilos, permitindo a obten\u00e7\u00e3o de um estilo uniforme em aplica\u00e7\u00f5es h\u00edbridas que combinam widgets cl\u00e1ssicos e elementos baseados no Qt Quick.   <center><img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/10\/9d96abe079bff0d8e9549f7ba9de691a.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> As capacidades do m\u00f3dulo Qt Graphs foram expandidas. Para gr\u00e1ficos 2D, novas propriedades foram implementadas para personalizar r\u00f3tulos de eixos e foi adicionado suporte a eixos logar\u00edtmicos. A\u00e7\u00f5es embutidas para zoom e panor\u00e2mica foram acrescentadas. Uma op\u00e7\u00e3o foi adicionada para renderiza\u00e7\u00e3o por meio de um backend de alto desempenho baseado no m\u00f3dulo CanvasPainter, permitindo a visualiza\u00e7\u00e3o de grandes volumes de dados em r\u00e1pida mudan\u00e7a.\n<li class=\"l\"> No Qt Quick foram adicionados os tipos QML Safe Area, Context Menu, Double Spin Box e Search Field para a exibi\u00e7\u00e3o de conte\u00fado n\u00e3o sobreposto, menus contextuais, formul\u00e1rios de input num\u00e9rico e campos de envio de consultas de busca. O tipo QML FlexboxLayout foi expandido para permitir o arranjo adapt\u00e1vel de elementos de interface de acordo com o conceito Flexbox, aplicado no CSS para facilitar o alinhamento vertical dos elementos.\n<li class=\"l\"> No m\u00f3dulo Vector Image, que permite integrar imagens vetoriais em cenas Qt Quick para criar elementos de interface escal\u00e1veis, foram adicionadas propriedades e capacidades de anima\u00e7\u00e3o adicionais para imagens nos formatos SVG e Lottie.\n<li class=\"l\"> A classe QRangeModel foi ampliada, fornecendo uma interface sobre o QAbstractItemModel para uso direto em elementos de interface baseados em QML e Qt Quick de quaisquer tipos enumerados em C++, incluindo std::vector, std::tuples e std::array. A nova vers\u00e3o inclui suporte para ordena\u00e7\u00e3o de dados, novas propriedades para controle de movimenta\u00e7\u00e3o no modo 'Drag &amp; Drop', aumento da velocidade na busca atrav\u00e9s do m\u00e9todo match(), al\u00e9m de oferecer configura\u00e7\u00f5es para cabe\u00e7alhos e linhas\/elementos individuais.\n<li class=\"l\"> No m\u00f3dulo gRPC foram adicionadas ferramentas para compress\u00e3o de mensagens no lado do cliente e para limitar o tamanho das mensagens de entrada de <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/server\/dts-los-angeles\/\"   title=\"servidor\" data-wpil-keyword-link=\"linked\">servidor<\/a>.\n<li class=\"l\"> No motor QML, foi implementado um mecanismo de Hot Reload que permite editar o c\u00f3digo QML em tempo real durante a execu\u00e7\u00e3o do programa e observar atrav\u00e9s do qmlpreview o resultado sem reiniciar ou interromper a execu\u00e7\u00e3o do aplicativo.\n<li class=\"l\"> Foi oferecido suporte LTS para a plataforma HarmonyOS, simplificando a migra\u00e7\u00e3o de aplicativos Qt existentes para smartphones, tablets, PCs e sistemas de infotainment automotivo da Huawei.\n<li class=\"l\"> Atendidas as exig\u00eancias da legisla\u00e7\u00e3o europeia Cyber Resilience Act (CRA), visando manter a seguran\u00e7a do produto, resolver vulnerabilidades de forma \u00e1gil durante o ciclo de vida e divulgar informa\u00e7\u00f5es sobre vulnerabilidades e incidentes de seguran\u00e7a. Componentes cr\u00edticos para a seguran\u00e7a foram destacados no c\u00f3digo-fonte, foi organizada a publica\u00e7\u00e3o de informa\u00e7\u00f5es sobre testes de seguran\u00e7a e garantida a
