# ObjectIO

[ObjectIO][objectio] is a [Clean][clean] library "to create Clean programs that have a Graphical User Interface (GUI)". There is [a tutorial][objectio_tut] available. Unfortunately, support is limited to Windows and Mac for the moment. In the [complete sources of Clean 2.4][clean_download], however, a start has been made to support Linux as well using [GTK+ 2][gtk2]. The code in that download is buggy and unusable, especially on 64 bit systems.

This project is an attempt to fix the Linux variant of Clean's ObjectIO library. In the initial commit the source code from the [Clean 2.4 sources][clean_download] has been copied. All other commits were authored by [Camil Staps][camilstaps].

## Legal

The ObjectIO library is subject to the [Clean License Conditions][clean_license], which means it is available under the LGPL and a commercial license.

This project however is licensed under the GPL 3.0 license. For more information, see the LICENSE file.

## To do

* This project is still in early development. Some simple programs (like "Hello World") are already working. However, many things are not working yet and many things still remain untested.
* In a future version, it would be preferable to switch to GTK+ 3.
