Yesterday, the team behind Qt announced the release of Qt 5.13. This release comes with fully-supported Qt for WebAssembly, Chromium 73-based QT WebEngine, and many other updates. In this release, the Qt community and the team have focused on improving the tooling to make designing, developing, and deploying software with Qt more efficient.

Following are some of Qt 5.13 highlights:

Fully-supported Qt for WebAssembly

Qt for WebAssembly makes it possible to build Qt applications for web browsers. The team previewed this platform in Qt 5.12 and beginning this release Qt for WebAssembly is fully-supported. This module uses Emscripten, the LLVM to JavaScript compiler to compile Qt applications for a web server. This will allow developers to run their native applications in any browser provided it supports WebAssembly.

Updates in the QT QML module

The QT QML module enables you to write applications and libraries in the QML language. Qt 5.13 comes with improved support for enums declared in  C++. With this release, JavaScript “null” as the binding value will be optimized at compile time. Also, QML will now generate function tables on 64-bit Windows making it possible to unwind the stack through JITed functions.

Updates in Qt Quick and Qt Quick Controls 2

Qt Quick is the standard library for writing QML applications, which provides all the basic types required for creating user interfaces. With this release, support is added to TableView that allows hiding rows and columns.

Qt Quick Controls 2 provides a set of UI controls for creating user interfaces. This release brings a new control named SplitView using which you can lay out items horizontally or vertically with a draggable splitter between each item. Additionally, the team has also added a cache property to the icon.

Qt WebEngine

Qt WebEngine provides a web browser engine that makes embedding content from the web into your applications easier on platforms that do not have a native web engine. This engine uses the code from the open-source Chromium project.

Qt WebEngine is now based on Chromium 73. This latest version supports PDF viewing via an internal Chromium extension, Web Notifications API, and thread-safe and page-specific URL request interceptors. It also comes with an application-local client certificate store and client certificate support from QML.

Lars Knoll, Qt’s CTO and Tuukka Turunen, Qt’s Head of R&D will be holding a webinar on July 2 to summarize all the news around Qt 5.13.
