Re: PerlGTK with GTK module written in C ?

Hi Muppet,
    Nice. Thanks for spending some time for my query :)

Is there a way in which I can integrate at-least Perl / Python. Then that will be of great.

What do you suggest me.

so you're wanting a gtk module (a chunk of code which can be loaded
dynamically by gtk+ itself) which is implemented in something other than

so, for example, you could have a python program which loads pygtk and
triggers the loading of a gtkmodule written in perl.

this is possible, but rather involved.  you'll have to have C code to
implement the entry points of the gtk module for gtk+ to call, and the
main entry point gtk_module_init() will have to start a new embedded
interpreter (perl, python, jvm, etc -- C++ is a special case that
doesn't need all of this) which will then execute the correct code on
callbacks and such.  this module code should register callbacks for
signals, and all that *should* Just Work, but the devil is in the
details.  note that the perl/python/scheme/java interpreter won't be
running all the time, only when explicitly invoked (i have never used
gtk2-perl in this way, but i believe this is how the gimp uses scheme).

does that make sense?
