The Qt Company Blog: Qt Creator 4.6 Beta released

We are happy to announce the release of Qt Creator 4.6 Beta!

C++ Support

The possibly most noteworthy and least directly visible change is that we upgraded the backend for the Clang code model from Clang 3.9 to Clang 5.0. This enables support for many C++17 features that were not available in Clang 3.9. The Clang code model is not used by default. Open Help > About Plugins (Qt Creator > About Plugins on macOS) and turn on the ClangCodeModel plugin to enable it.

Another feature that is not visible until you enable it, is the new option to integrate Clang-Tidy and Clazy warnings into the diagnostic messages that you see in the C++ editor. 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.

The informational tooltips on symbols are now generated from information from Clang instead of the built-in model (if you enabled the Clang code model). It now resolves auto to the actual type and shows template parameters for template types. It shows 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.

Navigation

We added 3 more filters to Locator. Type “b” 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” 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 Stuff.
Use “=” 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 has breadcrumbs for the file path at the top, and we added actions for adding, removing, and renaming files to its context menu.
