NOTE: This work is partly based on earlier works of J. Mansour and has been supported by A. Rumpf, E. Bassi and other _Nim_ and _GTK/Gnome_ developers.

This version will have some internal cleanup, which removes the temporary

Array types. In the past we used that names to indicate array parameters, it was working well, but still

it was ugly using names to indicates data types. So we fixed that. And we have added some better support for

Please let us know if these changes should break something for ordinary gtk users.

a C example, it seems to compile and run. But we have not tested real communication between

different computers yet, and not tested it on windows at all. If you have a use case for libnice you may test it yourself,

possible issues may Nim's string vs seq[uint8] vs plain ptr char, or the uint data types in C example which we replaced

by plain int as used in Nim prefereable. Debugging should be not hard, if you do not manage it yourself then you may

open a github issue. Version v0.8.3 uses also some more light entities like gtk.TextIter or glib.Mutex, that are entities
|
||||
which are generally allocated on the stack and are only initialized to plain binary zero. For these types no
|

proxy symbols are needed. Unfortunately discovering these entities by use of gobject-introspection works
|
||||
not reliable, so we are using a manually created list, which may contain errors.

And finally with v0.8.3 the examples from the GTK4 book (http://ssalewski.de/gtkprogramming.html) should work.

For the GTK3 examples we had to do some minimal fixes, so you may have to do similar fixes for your own code as well.
