Re: How to rethrow exception or install exception handlers inside Gtk::Main::run

[Yann LEYDIER <yann leydier info>]

Almost undocumented:

sigc::connection add_exception_handler(const sigc::slot<void>& slot);

In the callback, you can do something like this:
try
{
	throw;
}
catch (Glib::Exception &ex)
{
	std::cerr << "Glib/Gtk error: " << ex.what().c_str() << std::endl;
}
catch (std::exception &ex)
{
	std::cerr << "Unhandled exception: " << ex.what().c_str() << std::endl;
}
