We are happy to announce the release of Qt Creator 12!
New Features
Integrated Compiler Explorer
Use Tools > Compiler Explorer > Open Compiler Explorer to open an editor that integrates the Compiler Explorer from https://godbolt.org. While you write code, Qt Creator asks Compiler Explorer to compile it, generate assembly, and optionally execute it, and shows you the result, just like on their website. You can open multiple editors and configure different compilers. Save your document including the settings as a .qtce file for sharing or continuing you experiments later. The plugin is disabled by default, so first enable the plugin in Help > About Plugins > CompilerExplorer (or Qt Creator > About Plugins > CompilerExplorer on macOS).
CMake Debugging and Profiling
CMake 3.27 and later include debugging functionality via the Debug Adapter Protocol (DAP). Qt Creator 12 implements debugging via DAP in Debug mode > DAP, which means that you now can set breakpoints in your project's CMake files and debug CMake's configuration process. Instead of going through the Debug mode, you can also trigger CMake debugging more directly with Debug > Start Debugging > Start CMake Debugging.
Additionally, the new Analyze > CMake Profiler starts CMake in profiling mode (available since CMake 3.18) and opens the results in Qt Creator's trace file viewer.
Screen recording
Easily create recordings of (a part of) your screen for bug reports, sharing, blog posts, etc. Of course I've created the above with the ScreenRecorder plugin ;). The plugin is disabled by default, so first enable the plugin in Help > About Plugins > ScreenRecorder (or Qt Creator > About Plugins > ScreenRecorder on macOS).
Other Improvements
The following is just an excerpt. Please have a look at our change log for further details on improvements and fixes in Qt Creator 12. Also head over to the separate blog post with more details on the improvements on the CMake integration.
General
- We improved the startup performance significantly on various setups.
Editing
- We updated Clangd and the Clang analyzer tools to LLVM 17.0.1
- The C++ refactoring operations received multiple fixes and extensions. For example, renaming operations are now also applied to documentation comments.
- The Markdown editor got some buttons for text styles.
- We added proxy support to the Copilot integration.
Projects
- We added project specific settings for C++ file naming and documentation comments.
- The editor for CMake files received many improvements, like jumping to function, macro, target and package definitions, help tooltips and greatly expanded completion.
- PySide installations from the installer are now auto-detected.
A note for commercial users: Even though Qt Creator 12 counts as an "Upgrade" in terms of the license agreement, Qt Creator 12 is available free of charge for commercial users.
Get Qt Creator 12
The opensource version is available on the Qt download page under "Qt Creator", and you find commercially licensed packages on the Qt Account Portal. Qt Creator 12 is also available as an update in the online installer. Please post issues in our bug tracker. You can also find us on IRC on #qt-creator on irc.libera.chat, and on the Qt Creator mailing list.
You can read the Qt Creator Manual in Qt Creator in the Help mode or access it online in the Qt documentation portal.
Commenting for this post has ended.
On my Linux Mint 21.2, Qt Creator did not start after update. Ran
ldd lib/Qt/plugins/platforms/libqxcb.sowhich showedlibxcb-cursor.so.0 => not found. Seems there is some new dependency here? So installed it with:sudo apt install libxcb-cursor0Then Qt Creator finally started.
Same on Rocky Linux 8. Had to do
sudo yum install xcb-util-cursor. It's disastrous UX. Need a new dependency? Fine (sucks if you can't install packages), TELL user about it. Can't detect that in the installer? At least mention it in BIG BOLD LETTERS in the blog post, it's important.Coincidentally, after fixing this I've got greeted with Bookmarks plugin failing due to
Could not resolve dependency 'Core(11.0.3)' Could not resolve dependency 'ProjectExplorer(11.0.3)' Could not resolve dependency 'TextEditor(11.0.3)'Very good first impression of the update.I've created https://bugreports.qt.io/browse/QTCREATORBUG-30004 to track the
libxcb-cursorissue.This is something that the Linux users will have to deal with. See https://bugreports.qt.io/browse/QTBUG-108796 for more details.
I wonder why "Compiler Exploler" send code to server? Why not just ask compiler to generate assembler and show it to user?
One of the useful features of the Compiler Explorer is the ability to compare the generated assembler from different compilers and libraries that you might not have installed (or not installed in that version), and various other features. I guess nothing (aside from additional effort) would speak against having a simpler, locally working action in addition, though.
Yes please, running local analysis would be a very appreciated thing. This would enable private or company code to be explored without the question of what happens, when the code leaves the house. And thanks for this awesome release. Release 12 is a really big step forward!
You can have an instance of Compiler Explorer running locally. See https://github.com/compiler-explorer/compiler-explorer/issues/2469
Regression: Darg&drop CMakeLists.txt from welcome screen doesn't work (at least on Linux).
Thanks, we have created https://bugreports.qt.io/browse/QTCREATORBUG-29961 to track this.
On a regular 1080p screen the context menu became unusable. It just fills the WHOLE screen. Is there a way to remove some entries from it (I definitely don't need to see save bom) in the options?
the internal default c++ code model can't detect errors. I don't know why?! also, when I check useclangd, it detects errors that are not errors already, and the project builds fine.
What about per-project kits? Currently CMkae presets are converted to kits which are visible to all projects, which is kinda weird. Please have a look at https://wiki.qt.io/Loading_a_Qt_Creator_minidump_crash_file_on_Windows snow rider 3d and upload a minidump to a bugreport.
