Qt 6.12 bietet Unterst\u00fctzung f\u00fcr die Plattformen 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 und QNX. Der Quellcode der Qt-Komponenten wird unter den Lizenzen LGPLv3 und GPLv2 bereitgestellt.     <\/p>\n<p>Qt 6.12 hat den Status eines LTS-Releases erhalten, f\u00fcr das Updates \u00fcber einen Zeitraum von f\u00fcnf Jahren f\u00fcr Inhaber einer kommerziellen Lizenz bereitgestellt werden. F\u00fcr nichtkommerzielle Nutzer betr\u00e4gt die Unterst\u00fctzungsdauer ein halbes Jahr (bis zur Ver\u00f6ffentlichung eines neuen signifikanten Releases). Die Unterst\u00fctzung der vorherigen LTS-Version Qt 6.8 wird bis Oktober 2029 fortgesetzt, w\u00e4hrend die Unterst\u00fctzung der vorletzten LTS-Version Qt 6.5 in diesem Jahr eingestellt wurde.    <\/p>\n<p>Haupt\u00e4nderungen in Qt 6.12:  <\/p>\n<ul>\n<li class=\"l\"> Das Modul Qt Canvas Painter wurde als bereit f\u00fcr den breiten Einsatz anerkannt und stellt eine API f\u00fcr die hardwarebeschleunigte Darstellung von 2D-Inhalten zur Verf\u00fcgung, die Shader zur Erstellung komplexer visueller Effekte verwendet. Die Darstellung erfolgt \u00fcber die RHI (Rendering Hardware Interface), die verschiedene 3D-APIs (OpenGL, Vulkan, Metal und Direct 3D) unterst\u00fctzt. Auf Basis von Canvas Painter wurde ein experimentelles Element Canvas2D entwickelt, das sich an der HTML-Spezifikation f\u00fcr den Canvas 2D Context orientiert und die Verwendung von JavaScript zur Darstellung von Formen erleichtert.      <center><img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/10\/b130355f4d5e4c516d003a11e19eac36.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> Ein experimentelles Modul StyleKit wurde hinzugef\u00fcgt, das die Struktur der Benutzeroberfl\u00e4chenkomponenten und die Stileigenschaften klar trennt, womit sich das Duplicating von Code bei der Implementierung von hellen, dunklen und hochkontrastierenden Themen vermeiden l\u00e4sst. StyleKit bietet eine einheitliche QML-API zur Beschreibung von Stilen, die einen einheitlichen Stil in hybriden Anwendungen erm\u00f6glicht, die klassische Widgets und Elemente auf Basis von Qt Quick kombinieren.   <center><img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/10\/9d96abe079bff0d8e9549f7ba9de691a.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> Die Funktionen des Qt Graphs-Moduls wurden erweitert. F\u00fcr 2D-Diagramme wurden neue Eigenschaften zur Anpassung der Achsenbeschriftungen implementiert und die Unterst\u00fctzung f\u00fcr logarithmische Achsen hinzugef\u00fcgt. Eingebaute Aktionen f\u00fcr das Zoom- und Pan-Steuern wurden erg\u00e4nzt. Eine Option zur Darstellung via einem leistungsstarken Backend auf der Basis von CanvasPainter wurde hinzugef\u00fcgt, die die Visualisierung gro\u00dfer Mengen schnell wechselnder Daten erm\u00f6glicht.\n<li class=\"l\"> In Qt Quick, the QML types Safe Area, Context Menu, Double Spin Box, and Search Field have been added to display unoverlapping content, context menus, numeric input forms, and search query submission fields. The QML type FlexboxLayout, intended for responsive layout of interface elements according to the Flexbox concept used in CSS for easier vertical alignment of elements, has been expanded.\n<li class=\"l\"> The Vector Image module, which allows the integration of vector images into Qt Quick scenes for creating scalable interface elements, has added additional properties and animation capabilities for images in SVG and Lottie formats.\n<li class=\"l\"> Die Klasse QRangeModel wurde erweitert, um eine Einbettung \u00fcber QAbstractItemModel f\u00fcr die direkte Verwendung in QML-basierten Benutzeroberfl\u00e4chen und Qt Quick mit allen aufgelisteten Typen aus C++, einschlie\u00dflich std::vector, std::tuples und std::array, bereitzustellen. In der neuen Version ist Unterst\u00fctzung f\u00fcr die Daten sortierung integriert, neue Eigenschaften f\u00fcr die Steuerung der Verschiebung im &laquo;Drag &amp; Drop&raquo;-Modus implementiert, die Suche \u00fcber die Methode match() beschleunigt und es wurden Einstellungen f\u00fcr \u00dcberschriften und einzelne Zeilen\/Elemente bereitgestellt.\n<li class=\"l\"> Additionally, the gRPC module has added tools for compressing messages on the client side and limiting the size of incoming messages from <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/de\/server\/dts-los-angeles\/\"   title=\"Server\" data-wpil-keyword-link=\"linked\">Server<\/a>.\n<li class=\"l\"> The QML engine has implemented a Hot Reload mechanism, allowing QML code to be edited on the fly during program execution and observe the result through qmlpreview without restarting and stopping application execution.\n<li class=\"l\"> LTS support for the HarmonyOS platform has been provided, simplifying the migration of existing Qt applications to Huawei smartphones, tablets, PCs, and automotive infotainment systems.\n<li class=\"l\"> The requirements of the European Cyber Resilience Act (CRA) have been met, aimed at maintaining product security, promptly addressing vulnerabilities throughout the lifecycle, and disclosing information about vulnerabilities and security incidents. Components critically important for security have been highlighted in the source code, information about security testing has been organized for publication, and the integration of current versions of third-party libraries has been ensured.      <\/ul>\n<p>  <center>  <div class=\"youtube-placeholder\" data-id=\"z01rANRcIRs\" onclick=\"loadVideo(this)\">\r\n        <img decoding=\"async\"
