Qt Creator comes packed with several tools for helping you write and edit code easier, as you can use the incremental and advanced search function, perform code refactoring operations in order to find and rename symbols, as well as configure the source code editor in terms of font, color, and indentation. A powerful IDE fit for beginners and experienced programmers alike When it comes to configuring the settings of a new project, you can select the type of the utility that you want to create (Qt Quick or HTML5 or Qt widgets), set the programming language, use a version control system, as well as design separate versions of the project files.ĭeveloping QT Quick applications and widget-based utilities can be done with two integrated visual editors (Qt Quick Designer and Qt Designer). What’s more, the program lets you build, run, and deploy QT applications for desktop environments and mobile devices, use the debugging mode for analyzing the state of applications (it integrates several debuggers, such as GNU Symbolic Debugger, Microsoft Console Debugger, and JavaScript), as well as design installation packages that can be published on different application stores and channels. Integrated debuggers, visual editors for UI design, and other programming tools Qt Creator features several tools designed to help you customize the layout of the programs that you are creating and a built-in text editor that offers support for C++ and QML programming languages, syntax highlighting, as well as code completion and code syntax checking options. Advanced editor with support for QML and C++Īlthough it comes packed with a multitude of dedicated parameters, it sports a clean and straightforward interface that gives users the possibility to set up a new project by using the step-by-step approach, which comes in handy especially for rookies as they are offered assistance throughout the entire process. To be safe it would be best not to distribute the GPL components at all together with your application.Qt Creator is a cross-platform utility that works through an integrated development environment (IDE) for helping developers create applications for desktop and mobile device platforms. If you don't want to release the source code of your whole application, you must avoid distributing GPL applications in a way that combines it with your application. Note that some components of the Qt framework may be GPL licensed, and not LGPL. Basically, the LGPL requires that you document the process for replacing your version of the LGPL library (Qt) with another version that the user may have built herself. In practice it also means that on platforms like iOS and Android, LGPL is not really usable (because these platforms apparently do not allow users to replace the libraries with another version). on Windows, the Qt libraries must be DLLs, and on Linux the libraries for Qt must be. In practice this means that you must use dynamically linked libraries for the LGPL library (i.e. Make it possible for a user to use a different version of that LGPL library with your application. the Qt libraries), and also that you allow your users to replace the LGPL libraries with alternative versions.īasically what this has been interpreted to mean is that if you distribute LGPL libraries (such as Qt) with your application, then you also must:ĭistribute to your users the source code of the same version of that library, or make it available in a way that is conformant with the LGPL license. Namely, the obligation for the LGPL is that you distribute the source code of the LGPL libraries themselves (i.e.
Qt creator free license#
Note that the terminology "commercial license" is a bit ambiguous, because the (L)GPL license also allows 'commercial' use as long as you can follow the obligations.
Qt creator free software#
My question is, do I need a commercial license for the framework even though I don't want to sell the software and the source code is free for all employees of the corporation?Īs long as you can comply with the (L)GPL requirements of the Qt libraries, then you do not need to purchase a "commercial license" from the Qt Company.
