The fact that you are seeing a cobject in python indicates that gtkhtml2 is saying the signal argument is a G_TYPE_POINTER. Essentially, gtkhtml2 needs to be fixed in this regard. The code generator makes boxed types very easy to wrap. If the HtmlStream doesn't match the memory management characteristics of a boxed type (ie. registering copy/free functions), and they won't convert it to a GObject, then try and convince them to register a type derived from G_TYPE_POINTER. Which reminds me, I need to add support for easy wrapping of derived G_TYPE_POINTER objects to python to handle GtkCTree again, as GtkCTreeNode isn't a boxed type (again).

Get the authors to register it as a boxed type.

I can now successfully display an HTML document in Python code using the GtkHtml2 widget. I have so far only wrapped the HtmlDocument and HtmlView classes. I'm onto the next step: displaying embedded images. I'm unsure which route to take to get there. The HtmlDocument class supports a request-url signal. When I connect to it, my signal handler gets three arguments, a document, a url, and an HtmlStream*. The simple example that comes with GtkHtml2 doesn't do anything with it, but I presume I am supposed to write the image data I retrieve to the stream. Since I have yet to wrap this class, I don't actually see an HtmlStream*, but a PyCObject. HtmlStream is not a subclass of GObject, so I'm unclear how I am supposed to wrap it so that it is automagically mapped to the right kind of Python object. Any suggestions?

Re: [pygtk] adding wrappers for gtkhtml2
for example, when I wrapped atk: add atkmodule.la to pyexec_LTLIBRARIES. add: atkmodule_la_LDFLAGS = -module -avoid-version -export-symbols-regex initatk atkmodule_la_SOURCES = \ atkmodule.c \ atk.c atkmodule_la_LIBADD = $(ATK_LIBS) add: atk.defs atk.override to EXTRA_DIST The generic rule in pygtk cvs will handle the autogenerating.

[pygtk] adding wrappers for gtkhtml2
I decided to wrap the gtkhtml2 library today. Seemed easy enough, small gtkhtml2.defs and gtkhtml2.override files did the trick, or so I thought. Then I started wading through the morass known as autoconf/automake/etc and quickly gave up on trying to do it "right". I ended up simply editing pygtk/gtk/Makefile, trying to mimic what was there for gtk and gobject. I eventually got to the point where I had something that compiled, linked and installed. Now I get a segfault during import, which I have trouble stepping up to because it's in a shared library. *sigh* Does anyone have a "recipe" for adding new wrappers to PyGtk2? I believe I have suitable .defs and .override files. I need the rest of the glue. wrapping-other-libraries-was-never-this-hard-ly, y'rs, Skip ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk
