Since version 2.12, GTK+ provides #GtkBuilder to construct user interfaces from XML descriptions, similar to the functionality provided by #GladeXML in the libglade library. A good way to start a migration from libglade to GtkBuilder is to run the gtk-builder-convert utility on your glade file, and inspect the resulting output. If your code uses the @root parameter of glade_xml_new(), you may want to split your glade file into multiple GtkBuilder files by using the --root option of gtk-builder-convert. Alternatively, you can use gtk_builder_add_objects_from_file() to construct only certain objects from a GtkBuilder file. While GtkBuilder strives to be a complete replacement for libglade, there are a number of areas where it is currently still behind libglade: GtkBuilder supports context information in translatable properties in a slightly different way than libglade. Intltool does not yet support this; see bug 454894 for the current status of intltool support for GtkBuilder files. Thankfully, context in translations is a rarely used feature, and if you are not using it, intltools glade format support works just fine for GtkBuilder files. More details about migrating from libglade to GtkBuilder will appear here over time...
