PyGTK will be phased out with the transition to GTK version 3 and be replaced with PyGObject, [4] [5] which uses GObject Introspection to generate bindings for Python and other languages on the fly. This is expected to eliminate the delay between GTK updates and corresponding language binding updates, as well as reduce maintenance burden on the ...
GTK 2 is no longer supported, meaning some languages below do not have current GTK support. GObject (GOB) was initially written as a central component of GTK, but outsourced into GLib . GObject Introspection is a middleware layer between C libraries (using GObject) and language bindings, e.g. PyGObject uses this, while PyGTK does not.
After that, the client program can start sending GTK function calls in S-expression format as argument to the imported 'gtk' function. Before the GTK-server can execute GTK functions, it must read a configuration file in which the prototypes of the GTK functions are described. Since version 2.2.3 this also can be done on-the-fly, allowing the ...
GTK supports various backends, which provides different ways to display GTK applications depending on the system and environment. Examples of GTK backends are: Wayland – Used with the Wayland display server on Linux systems, it is a modern replacement for X11. X11 – The default on Linux systems using the X.Org display server.
The GNOME Project, i.e. all the people involved with the development of the GNOME desktop environment, is the biggest contributor to GTK, and the GNOME Core Applications as well as the GNOME Games employ the newest GUI widgets from the cutting-edge version of GTK and demonstrates their capabilities.
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).
For example, creating a subclass (even just a subclass of GObject) can require writing and/or copying large amounts of boilerplate code. [5] However, using Vala , a language that is designed primarily to work with GObject and which converts to C, is likely to make working with GObject or writing GObject based libraries nicer.
