The GPL v3 with special exception was later added as an added licensing option. The GPL exception allows the final application to be licensed under various GPL-incompatible free software/open source licenses such as the Mozilla Public License 1.1. Actions can be shared between menu options and toolbar buttons, so in this case, you reuse the actions that you created when you populated your menus in the preceding section. To populate the toolbar, click on an action on the Action Editor, then drag and drop it onto the toolbar.

Files under the project root and allow them in your home directory as described here. However, when converted into CMake, it can be opened and managed as a regular CMake application. You can also create a CMake-based Qt project in CLion using the New Project wizard. DO begin names of slots that are connected to signals with on.

Design, Develop & Deploy User Interfaces and Applications

Qt Designer provides a user-friendly graphical interface that allows you to quickly create GUIs. This can boost your productivity as a developer and shorten your development cycles.

What GUI to use with Python?

There are many graphical user interface (GUI) toolkits that you can use with the Python programming language. The big three are Tkinter, wxPython, and PyQt. Each of these toolkits will work with Windows, macOS, and Linux, with PyQt having the additional capability of working on mobile.

A declarative framework for building highly dynamic applications with custom user interfaces. Qt Essentials define the foundation of Qt on all platforms.

Language Features

When you’re creating your main windows, you might face situations in which you need to use multiple widgets in a given layout as your central widget. In addition to Qt Creator, Qt provides qmake, a cross-platform build script generation tool that automates the generation of Makefiles for development projects across different platforms. There are other tools available in Qt, including the Qt Designer interface builder and the Qt Assistant help browser , the Qt Linguist translation tool, uic , and moc (Meta-Object Compiler). Qt is used for developing graphical user interfaces and multi-platform applications that run on all major desktop platforms and most mobile or embedded platforms. Most GUI programs created with Qt have a native-looking interface, in which case Qt is classified as a widget toolkit. Non-GUI programs can also be developed, such as command-line tools and consoles for servers. An example of such a non-GUI program using Qt is the Cutelyst web framework.

Scale down to only the features and tools you need to achieve a smaller application footprint. Qt is full of tools to simplify developer’s lives and help with not just coding but also tasks like building, compiling, testing, localization, internationalization, localization, and more. We have guides, tutorials, ready-made code and a community to help you forward. Turn any mobile application or embedded screen into a revenue generator with the Qt Digital Advertising Platform. The Qt Company acquires Axivion GmbH to further strengthen its market-leading offering in quality assurance.

History of Qt

It doesn’t produce code in any particular programming language, but it creates .ui files. These files are XML files with detailed descriptions of how to generate Qt-based GUIs. Qt Designer also allows you to preview your GUIs using different styles and resolutions, connect signals and slots, create menus and toolbars, and more.

These actions are known as slots, which are methods or functions. All these built-in dialogs are ready for you to use in your code directly. Most of them provide class methods to build specific types of dialogs depending on your needs. Along with these dialogs, PyQt provides the QDialog class. You can use this class to create your own dialogs in code, but you can also use Qt Designer to create your dialogs quickly.
