Graphical user interface builder From Wikipedia, the free encyclopedia
Glade Interface Designer is a graphical user interface builder for GTK, with additional components for GNOME. In its third version, Glade is programming language–independent, and does not produce code for events, but rather an XML file that is then used with an appropriate binding (such as GtkAda for use with the Ada programming language). See List of language bindings for GTK for the available ones.

The first Glade release, version 0.1, was made on 18 April 1998.[6]
Glade 3 was released on 12 August 2006. According to the Glade Web site, the most noticeable differences for the end-user are:
Most of the difference is in the internals. Glade-3 is a complete rewrite, in order to take advantage of the new features of GTK+ 2 and the GObject system (Glade-3 was started when Glade-1 hadn't yet been ported to GTK+ 2). Therefore, the Glade-3 codebase is smaller and allows new interesting things, including:
On 5 April 2011, two parallel installable stable Glade versions[8][9][10] were released:
On 11 June 2015 Glade 3.19.0 was released. It depends at least on GTK+ 3.16.0. Among many bug fixes this version is the first to support the widgets GtkStack, GtkHeaderBar and GtkSidebar.[11]
GtkBuilder is the XML format that the Glade Interface Designer uses to save its forms. These documents can then be used in conjunction with the GtkBuilder object to instantiate the form using GTK. GladeXML is the XML format that was used with conjunction with libglade, which is now deprecated.[12]
Glade Interface Designer automatically generates all the source code for a graphical control element.
The "Gtk.Builder class" allows user interfaces to be designed without writing code.[13] The class describes the interface in an Extensible Markup Language (XML) file and then loads the XML description at runtime and creating the objects automatically. The Glade Interface Designer allows creation of the user interface in a WYSIWYG manner. The description of the user interface is independent from the programming language being used.
Code sketchers are software applications that help a user create source code from a GladeXML file. Most code sketchers create source code which uses libglade and a GladeXML file to create the GUI. Some sketchers are able to create raw code that does not need the GladeXML file. The table below compares basic information about GladeXML code sketcher packages.

Cambalache (/kambaˈlat͡ʃe/) is designed as a successor to Glade, with a focus on supporting the latest GTK 4 library while maintaining compatibility with GTK 3.[14] It is a free and open-source rapid application development (RAD) tool designed for creating user interfaces with GTK. Cambalache is geared toward developers working within the GNOME ecosystem. Cambalache's design emphasizes the Model-View-Controller (MVC) architecture, ensuring separation between the UI components and the business logic of applications.
The workspace, where users visually edit the UI, is powered by a separate component called Merengue. This uses Broadway, a GTK backend for web rendering, to display the UI elements in real-time without mixing different GTK versions in the same process. This architectural choice enhances stability by decoupling the user interface from the core application. The separation allows Cambalache to efficiently manage multiple versions of GTK simultaneously. As a result, the rendered UI closely emulates the appearance and behavior of the actual application.
