Please do report any bugs that you find. The examples build as part of the
source build, so nobody should be able to even install if the examples don't
build.

_All_ the methods? I don't think that would make a very clear example. The
examples should show you how to do the obvious useful things, and that's
what they are meant to do now. I'm happy to have links from the API
reference documentation, to the examples, or to the examples pages in the
book.

There are already links from the book chapters to the API reference and to
the actual example source code.

A little googling found me this:

  list_examples.push_back(RadioMenuElem(gr,"RadioItem Example 3");
  static_cast<RadioMenuItem*>(list_examples.back())->set_active();

which I admit is not very pleasant. The new UIManager in gtkmm 2.3 will be
similar, but takes a bool is_active when you create the Radio thingy.

I see that you've asked before, but it really is best to keep asking a
specific question rather than just asking non-specifically for things to be
generally better documented.
