Qt-Projekt vor<\/a><\/noindex> Framework-Edition f\u00fcr Mikrokontroller und energieeffiziente Ger\u00e4te \u2014 Qt f\u00fcr MCUs<\/a><\/noindex>. Zu den Vorteilen des Projekts geh\u00f6rt die M\u00f6glichkeit, grafische Anwendungen f\u00fcr Mikrocontroller zu erstellen, indem die gewohnte API und die Entwicklerwerkzeuge verwendet werden, die auch f\u00fcr die Erstellung vollst\u00e4ndiger GUIs f\u00fcr Desktop-Systeme genutzt werden. Die Benutzeroberfl\u00e4che f\u00fcr Mikrocontroller wird nicht nur mit der C++ API, sondern auch mit QML und den Qt Quick Controls-Widgets konzipiert, die f\u00fcr kleine Bildschirme optimiert wurden, die \u00fcblicherweise in der Unterhaltungselektronik, tragbaren Ger\u00e4ten, Industrieequipment und Smart-Home-Systemen verwendet werden. <\/p>\n

Um hohe Leistung zu erzielen, werden QML-Skripte in C++-Code \u00fcbersetzt, und die Rendering erfolgt mit einer separaten Grafikengine, die f\u00fcr die Erstellung grafischer Benutzeroberfl\u00e4chen unter Bedingungen von kleinem Arbeitsspeicher und begrenzten Prozessorressourcen optimiert ist. Die Engine wurde mit Blick auf Mikrocontroller der ARM Cortex-M-Serie entwickelt und unterst\u00fctzt 2D-Grafikbeschleuniger wie PxP auf NXP i.MX RT-Chips, Chrom-Art auf STM32-Chips und RGL auf Renesas RH850-Chips. Derzeit ist nur eine Demoversion verf\u00fcgbar,<\/a><\/noindex>.<\/p>\n

Zus\u00e4tzlich kann vermerkt werden Erstellung<\/a><\/noindex> unabh\u00e4ngigen Enthusiasten des Qt5-Ports f\u00fcr das Betriebssystem OS\/2. Der Port umfasst alle wesentlichen Teile des QtBase-Moduls und ist bereits f\u00fcr die Kompilierung und Ausf\u00fchrung einer gro\u00dfen Anzahl bestehender Qt5-Anwendungen unter OS\/2 geeignet. Zu den Einschr\u00e4nkungen geh\u00f6ren die fehlende Unterst\u00fctzung von OpenGL, IPv6 und Drag&Drop, die Unf\u00e4higkeit, das Mauszeigersymbol zu \u00e4ndern, sowie unzureichende Integration mit dem Desktop. <\/p>\n
