Eiffel/Gtk Interface

Gtk+ is a widget toolkit for X-window systems. Gtk+ appears to be the most popular open source toolkit available today on Linux. Although Gtk+ was developed to work with X-windows, a port to MS Windows exists. In principle you should be able to use the eGTK Eiffel bindings with Gtk+ on Windows.

The main goal of the eGTK library is to be portable among the various Eiffel compilers. The development is done with ISE and SmallEiffel compilers. Ports to Halstenbach and Visual Eiffel will be done at a later date.

The compilers being used are:

Please note that you must use SmallEiffel -0.78 because that's the first version that supports environment variables in "loadpath.se" files.

What's new?

December 15th, 1999 - version 0.3.4-1 released. Fixes to get rid of some SE warnings and some cleanup of obsolete classes.
December 10th, 1999 - version 0.3.4 released. Includes number of bugfixes, improvements to GTK_PIXMAP and GTK_WIDGET, and new examples. See CHANGELOG file for details.
October 25th, 1999 - removed all references to EIFFEL_GTK (replaced with EGTK) and renamed the archive file to eGTK-0.3.3-1.tar.gz.
October 15th, 1999 - version 0.3.3-1. Bug fixes in GTK_IDENTIFIED and related C code for 64-bit machines.
October 9th, 1999 - version 0.3.3. This is mainly a snapshot of current CVS, but many things changed (for details see CHANGELOG). Here are the highlights:
- Directories for the classes were rearranged. You have to adjust your Ace and loadpath.se files.
- Lots of new widgets added.
- Generalized memory management for all widgets (see EGTK_WIDGET_FACTORY).
- New examples.
6/2/99 - version 0.3.2 released. Many additions, new widgets, bug fixes etc. Revised design for handling callbacks - idea taken from Paul Janzen's and Francois Pennach's SmallEiffel library. We also named the library eGTK.
2/13/99 - added GTK_FILE_SELECTION widget and updated to work with Gtk+ 1.1.14.
1/2/99 - added GTK_DIALOG widget and a test in test_gtk. Fixed some classes that produced warnings under SE (thanks to all who pointed out the error).
12/16/98 - We now have a mailing list to discuss the Eiffel/gtk project. I also added a link to Paul Janzen's page which contains another version of the SmallEiffel/Gtk+ interface. My plan is to integrate this code into my library.
12/7/98 - I adapted the code to SmallEiffel. Now all of this library can be compiled with SmallEiffel (I'm using -0.79beta7).
7/25/98 - my code was retested with Gtk+ 1.0.4. I started to work on a canvas widget in Eiffel. I split handling of GDK events and GTK signals into separate classes.
3/11/98 - initial posting.

Developers

Current development team includes Dave E. Martin XIII, Oliver Elphick and Richie Bielak. Code was also contributed by Jörgen Tegne´r and we have "stolen" code and ideas from Francois Pennach and Paul Janzen's library.

Eiffel/Gtk Links

http://www.primenet.com/~pcj/eiffel-gtk - SmallEiffel/Gtk bindings by Paul Janzen and Francois Pennach. It's a complete binding, but it only works with SmallEiffel.
http://www.elj.com/dev/vegtk/ - VEGtk - binding of Gtk+ and Visual Eiffel. Although Visual Eiffel was developed on Windows, a Linux port is being beta tested.
http://www.eiffel.com - ISE also has a beta version of Eiffel Vision based on the GTK+ toolkit.

Applications written using Eiffel and one of the above bindings.

Frank Boehme wrote the game of Neutron and Co-Neurton, Niwie, using SmallEiffel and Paul Janzen's libraries.

Status

Current version: 0.3.2

Current code size: 11,500 LOC of Eiffel

Known problems:

The toolbars example does not work. It was created to show a bug in SmallEiffel compiler (a bug that has been fixed) and the example was never completed.
The GDK_IMAGE inherits from GDK_DRAWABLE. This is not correct.

TODO: - see the TODO files included in the archives. There is tons of work to be done.
