PerlGTK is pretty cool, it's relatively easy to
use if you know how to use it. Documentation
is completely lacking. I would not try to
program with it unless you've programmed with
GTK+ in some form or another previously. Most
things mimic the C calling sequece pretty well,
in reply to What ISN'T good about PerlGTK?
and so on.
The bad part is when you get into some of the C calls
that return things through the parameter list,
i.e. a function that returns a value, but takes
2 pointers in its arguments which it sets to
valuable information later. What is the way
to mimic this call? Should it return a list of
items that it normally would have assigned via
pointers, or should it do something else? If
it returns a list, then where are the gaps in
the arguments, etc.
A lot of figuring it out is hit and miss just
trying things out. Alternatively, you can dig
through the source code of the example programs
that come with perlgtk.
If you're comfortable with perl, perl objects,
and modules, and you've programmed with gtk
before, go for it. Otherwise, you might want to
wait until some documentation is out and about.
