You need to pass a PresenceWindow object into SigC::slot().

testlabel.signal_button_press_event().connect( SigC::slot(
my_window, &PresenceWindow::on_button_press_event )  );

should work if my_window is of type PresenceWindow.

BUT, you must not connect on_button_press_event() to
signal_button_press_event() or you risk entering an endless loop!
on_button_press_event() is a virtual function that you seem to override
correctly and that is triggered automatically if you call
add_events(Gdk::BUTTON_PRESS) from your PresenceWindow constructor.
