Qt Features, Framework Essentials, Modules, Tools & Add-Ons
Explore the modules and tools of the latest Qt release and product offerings from The Qt Company. Discover which development platforms, operating systems, and coding languages are supported, as well as how The Qt Company products are licensed and packaged.
Please select a package, license model, platform, or programming language to see, what items are available for that selection.
Note that multiple selections are not supported.
Note that the open-source license does not restrict running the tools. For example, GPLv3 affirms unlimited permission to run unmodified software. The license sets conditions to create and distribute derivate works. Using GPL v3-licensed Qt Creator does not imply that your software becomes GPL v3-licensed unless your software modifies existing software, which you are going to distribute and which is licensed under GPL v3.
