Cambalache

Cambalache is a user interface designer for GTK 4, specifically built to facilitate the creation of application layouts for the GNOME desktop environment. It utilizes the GtkBuilder format to generate XML files that define the structure and properties of interface components. The application provides a visual workspace where developers can drag and drop widgets, configure their attributes, and manage signal connections without writing manual XML code. It is intended to streamline the prototyping and development phase of GTK 4 applications.

The tool supports the complex object hierarchy inherent in GTK 4, allowing for the nesting of containers and the precise adjustment of widget properties. It is designed to be a specialized alternative to traditional interface builders, focusing on the specific requirements of the GTK 4 toolkit. Cambalache is available for Linux platforms and is licensed under the LGPL-2.1, making it suitable for integration into various development workflows that prioritize the GTK 4 framework.
