Glade is a GPL IDE tool to enable quick and easy development of user interfaces for the GTK+™ toolkit and the GNOME desktop environment. The user interfaces designed in Glade are saved as XML, and by using the GtkBuilder GTK+™ object these can be loaded by applications dynamically as needed. By using GtkBuilder, Glade XML files can be used in numerous programming languages including C™, C++™, Java™, Perl™, Python™, and others. The version marked "current" on their website is 3.10, which was released in April of 2011. It can be obtained from their ftp server: http://ftp.gnome.org/pub/GNOME/sources/glade/3.10/.
Their API reference manual is for version 3.6.6, which lists a total of 553 objects, counting their core, classes, widgets and utilities, and including the functions and properties of each. For a comparison, Qt™ 4.7 has over 800 classes, not counting the methods (functions) and properties of each class. This puts Glade well above FLTK but well below Qt™ in breadth and depth of the widget set. However, Glade is used to write GTK+™ GUI applications for GNOME, so it fits in well with GNOME's goal of a simplified Linux™ desktop.
