Qt 5.13 Released! Get it today
Today, we have released Qt 5.13 and I’m really proud of all the work that everyone has put into it. As always, our releases come with new features, updates, bug fixes, and improvements. For Qt 5.13, we have also been focused on our tooling that makes designing, developing and deploying software with Qt more efficient for designers and developers alike. Let’s take a look at some of the highlights of Qt 5.13 as well as some of the updates on the tooling side.
I will also be holding a webinar summarizing all the news around Qt 5.13 together with our Head of R&D Tuukka Turunen on July 2. Please sign up and ask us your questions.
Qt for WebAssembly
Qt for WebAssembly lets you build Qt applications for web browsers and is now fully supported. Qt for WebAssembly uses Emscripten to compile Qt applications for a web server allowing you to run native applications in any browser that supports WebAssembly without requiring a client-side installation. Qt is setting the pace for C++ development for WebAssembly and Google recently used Qt as an example of how to run C++ applications in the browser at the Google I/O ’19 event. You can take a look at the video.
We have also collected a range of examples for Qt for WebAssembly. Check out them out here.
Qt GUI summarises our classes for windowing system integration, event handling, OpenGL and Open GLES integration, 2D graphics, basic imaging, fonts, and text.
Qt Quick and Qt Quick Controls 2
The standard library for writing QML applications and our UI controls for creating user interfaces have also received some updates. We have added support to TableView for hiding rows and columns and for Qt Quick Controls 2 we have added SplitView, a control that lays out items horizontally or vertically with a draggable splitter between each item. We have also added a cache property to icon.
Qt WebEngine integrates Chromium’s fast-moving web capabilities into Qt and its latest version is now based on Chromium 73. We have added PDF viewing via an internal Chromium extension, application-local client certificate store, client certificate support from QML, Web Notifications API and a thread-safe and page-specific URL request interceptors.
Qt Network provides a set of APIs for programming applications that use TCP/IP and we have added Secure Channel support for SSL socket and OCSP stapling support. With Qt 5.13 are now using OpenSSL 1.1 to support SSL connections on Linux and Android.
Provides a rich set of QML types and C++ classes to handle multimedia content. We have also added gapless playback in QML VideoOutput using flushMode property, support of GStreamer for Windows/macOS and HTTP headers and audio roles for Android.
The client side of a client - KNXnet/IP server connection. This connection can be used to send messages to the KNX bus and to control the functionalities of the KNX devices typically used in building automation. With Qt 5.13, the module has received a secure client API.
Qt OPC UA
The next generation of Industry 4.0 applications based on a Client / Server architecture has received some updates. Mainly, the C++ API is now fully supported and we added tech previews of a QML API and a secure client C++ API.
Qt CoAP (Tech Preview)
Qt CoAP (Constrained Application Protocol) is a client-side implementation of the M2M protocol for use with constrained nodes and networks for the internet of things. With Qt 5.13, the module has received support for Datagram TLS (DTLS) over UDP.
Other Recent updates
Qt Creator IDE 4.9
Qt Creator IDE has received some updates, which include an improved UI for diagnostics from the Clang analyzer tools, a QML parser update, support for ECMAScript 7 and a new performance profiling plugin for software running on Linux. You can read more about the updates to Qt Creator in the dedicated release post.
Qt Design Studio 1.2
The latest edition of the Qt UI design and development tool now lets you seamlessly import your designs from Sketch (in addition to Photoshop) and turn them into QML code. Adding support for Sketch has been a sought-after request and is a popular tool for designers so this is really taking Design Studio to the next level, enabling a much smoother designer-developer workflow. In addition, support for more complex gradients from Qt Quick Shapes have been added, and various improvements and fixes have been made. We have also released a Qt Design Studio Community Edition. You can read more about it in the release blog post.
Qt for Python
Qt for Python has received a large number of bug fixes and improvements since its first officially supported version that came with Qt 5.12.
New Version of Qt Safe Renderer
TÜV NORD certifies that you can use Qt to build functionally safe embedded systems. The QSR 1.1 is certified based on the new edition of ISO 26262:2018 series of standards and includes Qt Safe Renderer Code, Designer and Build Tooling, ac safety manual, certification artifacts, and global Qt technical support. Our recent update allows you to render UI elements dynamically.
Qt Lottie Animation Tech Preview
Engineers and UI designers can now easily embed Adobe After Effect animations directly into Qt Quick applications using the Bodymovin export format and the new Qt Lottie renderer for it. For more details have a look at the blog post about it QtLottie.
Thanks to the Qt Community
Qt 5.13 adds new functionality and improvements. Some of them would not have been possible without the help of the great community who contributes to Qt with new functionalities, documentation, examples, as well as bug fixes and reports. There are too many people to mention, but I’d like to especially thank basysKom and Witekio for their work on Qt OPC UA and QtCoAP, respectively.
