libqt refers to a set of libraries that are used by applications to provide a graphical user interface (GUI) on various operating systems, including Linux, Windows, and macOS. Qt is a cross-platform application framework and toolkit that provides developers with a set of tools for creating applications with rich graphical user interfaces.
The Qt libraries provide a wide range of functions and widgets for building GUI applications, including buttons, text fields, checkboxes, sliders, and more. The libraries also provide support for multimedia playback, networking, and other features commonly used in modern applications.
Applications built using Qt can be compiled to run on multiple platforms without significant changes to the code. This makes Qt a popular choice for developing cross-platform applications, especially in industries such as automotive, healthcare, and industrial automation.
