I Qt 6.3 er der support for platforme som Windows 10, macOS 10.14+, Linux (Ubuntu 20.04, CentOS 8.2, openSUSE 15.3, SUSE 15 SP2), iOS 13+, Android 6+ (API 23+), webOS, INTEGRITY og QNX. Kildekoden til Qt-komponenter leveres under LGPLv3 og GPLv2 licenser.       <\/p>\n<p>Hoved\u00e6ndringer i Qt 6.3:  <\/p>\n<ul>\n<li class=\"l\"> I Qt QML-modulet er der en eksperimentel implementering af qmltc (QML type compiler), der muligg\u00f8r kompilering af QML-objektstrukturer til klasser p\u00e5 C++. For kommercielle brugere er Qt 6.3 udstyret med Qt Quick Compiler, som udover ovenst\u00e5ende QML Type Compiler ogs\u00e5 inkluderer QML Script Compiler, der muligg\u00f8r kompilering af funktioner og udtryk i QML til C++-kode. Det bem\u00e6rkes, at brugen af Qt Quick Compiler bringer ydeevnen af QML-baserede programmer t\u00e6ttere p\u00e5 native programmer; is\u00e6r ved kompilering af udvidelser, er der en reduktion af opstarts- og k\u00f8retider p\u00e5 omkring 20-35% sammenlignet med brugen af den fortolkede version.    <center><img decoding=\"async\" alt=\"Release of the Qt 6.3 framework\" src=\"\/wp-content\/uploads\/2022\/04\/4f0b259a1be701958d7f4abe4570dcc9.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> Modulet \"Qt Language Server\" er implementeret med st\u00f8tte for Language Server og JsonRpc 2.0 protokoller.\n<li class=\"l\"> I Qt Wayland Compositor-modulet er der tilf\u00f8jet en komposit\u00f8r. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/\"   title=\"server\" data-wpil-keyword-link=\"linked\">server<\/a> Qt Shell og API til oprettelse af egne udvidelser til brugerfladen.\n<li class=\"l\"> I Qt Quick Controls er QML-typerne CalendarModel og TreeView integreret med implementationer af gr\u00e6nseflader til visning af kalender og data i tr\u00e6format.    <center><img decoding=\"async\" alt=\"Release of the Qt 6.3 framework\" src=\"\/wp-content\/uploads\/2022\/04\/38fe22b8724882af4b7cb3a52fc388d9.jpg\" style=\"display:block;margin: 0 auto;\" \/><img decoding=\"async\" alt=\"Release of the Qt 6.3 framework\" src=\"\/wp-content\/uploads\/2022\/04\/78c551e7bbecab13fe00a8b76c9aa3b6.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> I Qt Quick Dialogs er der tilf\u00f8jet QML-typerne MessageDialog og FolderDialog til brug af systemdialoger fra platformen til visning af beskeder og filnavigation.    <center><img decoding=\"async\" alt=\"Release of the Qt 6.3 framework\" src=\"\/wp-content\/uploads\/2022\/04\/c7f4aa1f9144a25c10080de1612f167e.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> I Qt Quick er ydeevnen og effektiviteten ved arbejde med tekst blevet forbedret. For eksempel er der l\u00f8st problemer med forsinkelser ved rendering og stort hukommelsesforbrug ved overf\u00f8rsel af meget store dokumenter til Text, TextEdit, TextArea og TextInput-komponenter.\n<li class=\"l\"> Qt Quick 3D-modulet har f\u00e5et et QML-element ReflectionProbe til rendering af objekters refleksioner. API'et for 3D Particles er udvidet til at tilf\u00f8je effekter skabt af store m\u00e6ngder partikler (r\u00f8g, t\u00e5ge osv.) til 3D-scener. Et nyt element ResourceLoader er implementeret, hvilket giver midler til at h\u00e5ndtere ressourcer i Qt Quick 3D og muligg\u00f8r forudindl\u00e6sning af store ressourcer s\u00e5som meshes eller teksturer samt kontrol over muligheden for at frigive ressourcer, der ikke falder inden for den synlige del af scenen.    <center><img decoding=\"async\" alt=\"Release of the Qt 6.3 framework\" src=\"\/wp-content\/uploads\/2022\/04\/c12b813dbc20a716c9ddb79ae1a5a841.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> En tidlig implementering af Qt PDF-modulet, som var til stede i Qt 5.15, men ikke kom med i Qt 6, er blevet tilf\u00f8jet.    <center><img decoding=\"async\" alt=\"Release of the Qt 6.3 framework\" src=\"\/wp-content\/uploads\/2022\/04\/0dd7575ec29c72ac59441c6d2e490b40.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> Qt Core-modulet har f\u00e5et en betydelig m\u00e6ngde nye funktioner, prim\u00e6rt relateret til udvidelsen af mulighederne for behandling af strenge data. QLocale har f\u00e5et underst\u00f8ttelse af ISO639-2 sprogkoder. QDate, QTime og QLocale har f\u00e5et underst\u00f8ttelse af AM\/PM tidsformater. Konvertering mellem JSON og CBOR formater er forenklet. Metoderne QtFuture::whenAll() og whenAny() er blevet tilf\u00f8jet.\n<li class=\"l\"> I Qt Positioning er der tilf\u00f8jet mulighed for at bestemme pr\u00e6cisionen af placeringdata, der leveres af Android og iOS platforme.\n<li class=\"l\"> I Qt Bluetooth er der givet oplysninger om underst\u00f8ttelse af Bluetooth LE og statusoplysninger om Bluetooth-adapteren i Windows.\n<li class=\"l\"> I Qt Widgets er der forbedret underst\u00f8ttelse af h\u00f8jopl\u00f8sningssk\u00e6rme, stilarter og \u00e6ndringer af design ved hj\u00e6lp af stylesheets.\n<li class=\"l\"> Byggesystemet baseret p\u00e5 CMake er blevet forbedret. Funktionen qt-generate-deploy-app-script() er blevet tilf\u00f8jet for at forenkle genereringen af scripts til implementering af applikationer p\u00e5 forskellige platforme.\n<li class=\"l\"> Der er foretaget betydeligt arbejde for at forbedre stabiliteten og kvaliteten af kodebasen. Sammenlignet med udgivelsen af Qt 6.2 er 1750 fejlrapporter blevet l\u00f8st.\n<li class=\"l\"> I de kommende store udgivelser af Qt 6.x planl\u00e6gges der at implementere fuld st\u00f8tte til WebAssembly, QHttpServer, gRPC, backend til Qt Multimedia baseret p\u00e5 FFmpeg, Qt Speech og Qt Location.    <\/ul>\n<p>Kilde: <a content=\"nofollow\" rel=\"nofollow\"
