History and Development
The first Glade release, version 0.1, was made on April 18, 1998.
Glade 3 was released on 12 August 2006. According to the Glade Web site, the most noticeable differences for the end-user are:
- Undo and redo support in all operations.
- Support for multiple open projects.
- Removal of code generation.
- Contextual help system with Devhelp
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:
- Catalogs of "pluggable" widgets. This means that external libraries can provide their set of widgets at runtime and Glade will detect them. In fact, Glade 3 supports only standard GTK+ widgets; GNOME UI and DB widgets are provided separately.
- The various Glade Tools (palette, editor, etc.) are implemented as widgets. This allows for easier integration in IDEs like Anjuta, and makes it easier to change the Glade UI.
