I want to modify the primary message widget so I can select and copy the

This fails: Gtk-CRITICAL: 08:51:12.080: gtk_label_get_label: assertion
'GTK_IS_LABEL (label)' failed
So the primary message widget isn't a Gtk::Label. How do I determine
what it is?
Dynamic cast should do the job:

You can also use the *typeinfo* library as follows:
#include <typeinfo>
std::unique_ptr<Foo> foo( new Foo() );
std::string str = typeid(foo).name();
std::cout << str << std::endl;
Even though you should filter the outputs of special characters like ::
<> and so.
In this concrete case, the program will throw a bizarre output like this:
St10unique_ptrI4FooSt14default_deleteIS0_EE
On the other hand, if you have access to the *boost* library, you'll be
able to get a pretty name. Read here at the end of the post:

But i recommend you to pay attention to the dependencies of your project.
Hope this helps,
Aitor.
