Qt Creator 4.6.0 released

March 28, 2018 Eike Ziller

We are happy to announce the release of Qt Creator 4.6.0!

C++ Support

C++ is changing a lot these days, and to catch up with these developments we upgraded the backend for the Clang based code model from Clang 3.9 to 5.0. This enables support for many C++17 features that were not available in Clang 3.9. Since the ClangCodeModel plugin is not enabled by default, you have to make sure to enable it in Help > About Plugins (Qt Creator > About Plugins on macOS), to benefit from this upgrade.

Diagnostics and fixits in Qt Creator by clang-tidy and clazy

In the animation above you see our new integration of Clang-Tidy and Clazy warnings into the diagnostic messages in the C++ editor. Since some checks can be time consuming, and other checks can produce false positives to varying degrees, they are not enabled by default. To enable them go to Options > C++ > Code Model > Clang Code Model Warnings, create a copy of one of the presets, and choose the checks that you want to be performed.

If you enable the Clang code model, that is now also used for the informational tooltips on symbols in the editor. They now resolve auto to the actual type and show template parameters for template types. They show the first or the \brief paragraph of a documentation comment, too.

We also added separate highlighting of function definitions and fixed some issues with saving header files on Windows while Clang has a grip on them.


We added 3 more filters to Locator. Type “b<space>” to jump to a bookmark, filtering on file name and notes. The other two are not directly related to navigation but nevertheless useful.
The filter “t<space>” triggers an item from the main menu. You can either use the display name of the item to locate it, or parts of the menu path leading to it. For example “t sess expe” could be used to trigger the menu item File > Sessions > Experimental Something.
Use “=<space>” to evaluate simple ECMAScript (JavaScript) expressions. You have all functionality from the ECMA-262 specification at your disposal, and for convenience, we also added the functions from the Math object as global functions (so you can write “max(1, 2)” instead of “Math.max(1, 2)”).

We continued the work on the File System navigation pane that we started with 4.5. It now offers breadcrumbs for the file path at the top, and we added actions for adding, removing, and renaming files to its context menu.

Model Editor

Thanks to Jochen, the original contributor, the model editor received a big update in this release. First of all we removed the experimental state and made it available by default. We cleaned up the UI a bit, adding the zoom actions to the editor tool bar, and moving the export actions to the File menu. You can export only selected elements or the whole diagram to images. The editor now supports text alignment and multi-line object names. A wider range of panes now supports drag & drop of items.

There have been many more improvements all over Qt Creator. Please have a look at our changelog for a more detailed overview.
