Okay, so that works -- grabbing the child widget of the button and using
modify_fg on it.
It leaves the question, what does modify_text even do then? It doesn't seem to
change the text color on any widget, even a label, which seems most apparent
that it would. It appears that in other gtk libraries like python-gtk
modify_text will modify the label text color contained in any widget. So this
was probably not implemented correctly.

IMHO it would be enough to give them a different namespace then inside the same
library instead of a different library ;)
Also, GstBase contains gst-plugins-base stuff and Gst contains stuff of the
libgstbase library from core? That's confusing then ;)

I don't think this is possible. The C++ source files are not just handwritten,
they also go through a generation process from preliminary source files (.hg
and .ccg files). The namespace needs to stay constant for generated classes
throughout a branch (such as the gstreamer or the gstreamerbase branch) so that
the wrap_init() method (which is generated) knows how to generate
initialization code for classes. Feel free to look at the automake structure
and the generate_gst_wrap_init tool (and its usage in the build process) to
confirm this yourself.

GstBase is intended to wrap gst-plugin-base stuff so it should contain
gst-plugins-base stuff (I think). As far as Gst using libgstbase stuff, I
think that dependency got in there accidentally (I must have misunderstood
something), but it's fixed in svn, thanks:

* configure.ac: Remove gstreamer-base-0.10 as dependency of
gstreamermm.
As far as this bug is concerned, I'll be investigating further to see what can
be done. I'll post back with findings soon. This should be taken care of
before next release. Thanks.

Just so you know, this is the design I'm following for now:
The design is that gstreamermm includes (or will if the design is right)
GStreamer Core[1], GStreamer Library[2] and GStreamer Elements (or plugins)[3].
gstreamerbasemm, OTHO would include GStreamer Base Plugins Library[4] and (if
necessary and possible, which I think it should be) gst-plugins-base Elements
(or plugins)[5]. The links are all from the GStreamer docs page[6].

------- Comment #16 from Sebastian Dr?ge 2008-11-16 07:21 UTC -------
Ok, that makes sense then IMHO. One question though, how do you want to wrap
the plugins/elements? I mean, their instance/class struct sizes are not
guaranteed to stay the same as they're not part of the ABI. You could only
create hand-written wrappers that only access the elements via generic
interfaces like GObject properties, gstreamer interfaces, etc. Also
distributors might want to choose to not include some elements, it's not
guaranteed that everybody has audioresample for example :)
Then for gstreamer-base-0.10, you need it for Gst::BaseSrc and friends so this
should still be linked in, IIRC you're wrapping basesrc at least.
Whatever, for the design you're following now, it would still mean that
gstreamermm and gstreamerbasemm are using symbols from each other and depend on
each other, right? And that this is, because you don't want the application to
call a GstBase initialization function and because you can't let the source
generation put everything into one library and different namespaces, right? In
that case I guess this bug can't be properly solved ;)
