GtkAda: a complete Ada graphical toolkit
Our latest release
GtkAda 2.18.0 can now be downloaded directly from the GNAT GPL download area, in the tools/gtkada section.
Access to the latest snapshot using SVN
The GtkAda repository is accessible read-only by anonymous SVN. Note that you should only use the GtkAda SVN tree if you know what you are doing and if using a development version (with possible instabilities) does not frighten you. To check it out:
svn checkout http://svn.eu.adacore.com/anonsvn/Dev/trunk/GtkAda
You can also browse the repository directly.
If you would like to contribute, send your patches (contextual or unified diffs) and we will work with you on integrating them. If you have already contributed and would like write access to the tree, please contact us.
Introduction to Gtk+ and GtkAda
What is Gtk+?
Gtk+ is a wonderful graphic toolkit written in C for X-Window and Win32 that was originally developed as the basis for the gimp.
What is GtkAda?
GtkAda is an Ada graphical toolkit based on Gtk+, providing the complete set of Gtk+ widgets using the Object-Oriented features of this language. GtkAda supports the latest 2.18 stable releases.
Although this is not an obligation, we would really appreciate to hear from any new application using this toolkit. We will publish a list on this page. Hopefully, this will bring new people to this wonderful language that Ada is.
Status of this toolkit
This toolkit tries to map almost all the functions found in gtk and gdk. This is a thick binding, which means that while the functions are mapped on an almost one-to-one basis (a given Ada function is actually mapped to a single C function in most cases), we also tried to add a strong typing mechanism, which is one of the strongest feature of Ada. We are also now providing new features such as dynamic Glade support. The callbacks are mapped as generic packages which try to provide type safety. Along with this toolkit, you will find a lot of examples on how to use it. You will also find a few screenshots below.
- GtkAda User’s Guide
- GtkAda Reference Manual
- Glib C Reference Manual
- Gdk C Reference Manual
- Gtk+ C Reference Manual
- Gtk+/Gnome Application Development
We would also definitively appreciate any contribution or bug report from you. We will try to include them whenever possible, but since this project is done on our free time, we can’t promise to do anything within ten minutes following your mail. It will take us at least 15 minutes.
You will find lots of screenshots at the gtk web site. Here are a few extracted from our re-implementation of the testgtk program and the editor example.
We have been able to test GtkAda 2.18.x it on the following machines. Please let us know if you can use it/port it to other machines. As far as we know, it should work on every target supported by both Gnat and Gtk.
- GNU/Linux x86, ia64, x86-64
- Solaris sparc, x86
- Mac OS X x86-64
- FreeBSD x86
- Windows XP/Vista

Applications using GtkAda
More and more applications are being developed using GtkAda. This includes both commercial and non-commercial projects. Let us know if you have heard of any available application that you think should be included here. Here is a list of some of these applications.
- GPS, the GNAT Programming Studio is a powerful integrated development environment.
- Gate is the GtkAda translator that generates human readable code from the Glade GUI builder XML files.
- Dgate is a GtkAda testing tool that uses the dynamic XML loading capabilities of GtkAda.
- Gdialog is a simple utility that provides an easy way to display dialog boxes from shell scripts.
