Graphic DesignGTK

GTK (GIMP Toolkit)It is a set of powerful graphics toolkit across multiple platforms, released under the LGPL license agreement. Although it was originally written for GIMP, it has long since developed into a powerful and flexible design general-purpose graphics library. In particular, being selected by GNOME has made GTK+ widely spread and has become one of the mainstream development tools for developing graphical interface applications under Linux. Of course, GTK+ does not require that it must be on Linux. In fact, GTK+ already has a successful Windows version.

Software features

Although GTK+ is written in C language, you can use GTK+ in a language you are familiar with, because GTK+ has been bound to almost all popular languages, such as: C++, Guile, Perl, Python, TOM, Ada95, Objective C, Free Pascal, Eiffel, etc.

It is modern and actively developed and maintained, with a vibrant community surrounding it.

It offers a wide range of options for scaling your work to as many people as possible, including a comprehensive framework for internationalization, localization, and accessibility.

It's simple and easy to use, both for developers and users.

It's well designed, flexible and scalable.

It is free software and has a liberal open source license.

It is portable, both from a user and developer perspective.

Using a library like GTK+ has several advantages over writing your own GUI code. For example, it can significantly save development time, allowing developers to focus on the really important and truly unique parts of the project without having to duplicate common functionality. For users, this means better consistency between the apps they use: wherever the toolkit goes, the apps follow. Just like with LEGO, the fact that all are using the same compatible sizes means designs can be shared between people using the library, regardless of where they use it.
