Gtk::Widget::has_focus() tells you whether the widget has the focus.  To
get notification on focus changes, you should probably connect to
Gtk::Widget::signal_focus_in_event() -- but I never used it, look up the
GTK+ documentation for details.

Connecting to a signal is easy:

foo_widget->signal_bar().connect(
    SigC::slot(*this, &FuzzClass::bazz_method));

*this can actually be a reference to any object derived from
SigC::Object.  If you derive from the widget that provides the signal
you can alternatively override the corresponding on_bar() method
instead.

You won't see any example code until you tell us what "extended TreeView
code" is supposed to be ;)
