VeGtk is a Visual Eiffel binding of Gtk+. It allows you to
develop graphical applications in Eiffel using Gtk+.
This is not an official overview, but an attempt to make clear
why Object Tools has
released its version of GTK binding for Eiffel. This work was
performed as a part of Visual Eiffel
port to Linux platform. The
VEGTK library was compiled by VE on Win32 as well as on Linux.
The Linux version of the VE compiler will be available for beta-testing
We hope, you will enjoy using this library and it will get
better quality by our concerted action. We would like to hear any
comments and suggestions related to our design and implementation.
The primary developers of the library, that should be
contacted if you encontered any problems or questions are
Most widgets of the Gtk+ 1.2 series have been bound. The binding for the
Gdk part is not complete yet, but is already pretty much in place
Comprehensive testgtk (Examples/GTK/Test) program demonstrates the use of
most Gtk+ widgets

||VEGTK, Object Tools
|Number of widgets
||+ Almost all widgets
+ testgtk example practically identical to C
|Enums are implemented as
||+ Classes with type checking
+ Values of constants are specified in Eiffel code, that
is more efficient (though it may restrict flexibility)
||+ Callbacks do not require special
classes and can be used very naturally
- Callback features are not checked for type correctness
||+ VE, most code does not use VE-specific
features, easy to port to SE (and, maybe, ISE)
COMPARISON TO OTHER EIFFEL/GTK PROJECTS
See Pirmin Kalberer's page at http://www.spin.ch/~kalberer/gtk
This software has been developed and tested with
gtk+-1.2.1 and Visual Eiffel v2.91 Beta (Build 1299).
It will not work with gtk+ below 1.2.
The current version of the VEGTK distribution does not include
some useful features:
- examples from GTK tutorial are not implemented, though testgtk
overcovers all their functionality
- differences between C version of the GTK and VEGTK,
especially callbacks implementation, are not described,
though you can look into testgtk sources to
understand the details
- Win32 port of GTK sometimes does not work properly, but
this has no relation to Eiffel
This work is based some on ideas from Paul C. Janzen's and Francois
Pennaneach's eiffel-gtk -0.03 and Richie Bielak's Eiffel/gtk interface.
