We are happy to announce the release of Qt Creator 4.2 Beta.

Qt SCXML Editor

Qt SCXML is a new module in Qt that allows you to create state machines from State Chart XML and embed them into Qt C++ and Qt Quick applications (Overview). It was released as Technical Preview in Qt 5.7 and will be released fully supported with Qt 5.8.

Qt Creator 4.2 now supplements the module by offering a graphical editor for SCXML (experimental). It features editing states and sub-states, transitions, events, and all kinds of properties. The editor is experimental and the plugin is not loaded by default. Turn it on in Help > About Plugins (Qt Creator > About Plugins on macOS) to try it.

Projects Mode

We reworked how you select the project and it's diverse settings in Projects mode. Instead of nested tabs, you now select the project from a dropdown, and the settings that you want to edit from a tree that shows all available kits and other categories, making for a much cleaner UI. Enabling use of a kit for a project is now easily done by clicking the entry in the tree. Please provide feedback on any remaining issues through our bug tracker.

Qt Quick Designer

Qt Quick Designer has received many smaller features in this release. In the connections editor there is a new section for managing the imports and property definitions that are necessary for using C++ backend objects (documentation). Also support for padding (Qt Quick 2.6) was added, and you can now edit the when condition of states, and the diverse font properties of text items.

Other Additions and Improvements

When profiling your QML code you now have the option to show memory usage and allocations as flame graphs as well.

We added Tools > Diff > Diff Current File and Diff Open Files for showing a local diff of the modifications of files in Qt Creator with respect to their versions on disk.

Performance of opening CMake projects was improved, and support for predefined options for properties was added.

There were many more changes, which are described in more detail in our change log.
