GTK 4.20 has been officially released after six months of development, marking a significant milestone in the creation of graphic user interfaces. This latest version, known as gtk 4.20, aims to provide application developers with a stable and supported API that will remain consistent over several years. This eliminates the need for developers to constantly update their applications due to changes in the API with each new branch of GTK.
Some of the notable improvements in gtk 4.20 include:
- Support for input methods via the Wayland Protocol text-input, allowing users to manually set the environment variable “gtk_im_module = simple” to enable support for x11 compose sequences and diacritic sign input keys.
- Enhanced support for Wayland by adding processing restrictions on the edges of upper-level surfaces (XDG-TOPLEVEL EDGE Constraint). This feature enables composite managers to inform Wayland clients about restrictions related to window resizing.
- Introduction of support for the Wayland Protocol tablet-v2, improving input functionalities for graphic tablets.
- Enhancements in scrolling functionality using Wayland.
- Icon binding for windows in the Wayland Protocol xdg-toplevel-con.
- Simplification of symbolic icons and resources design, now processed by a built-in SVG format parser and providing themes in PNG format.
