Connect to FontSet signal.

The ::font-set signal is emitted when the user selects a font. When handling this signal, use [gtk.font_chooser.FontChooser.getFont] to find out which font was just selected.

Note that this signal is only emitted when the user changes the font. If you need to react to programmatic font changes as well, use the notify::font signal.

`after`	Yes.After to execute callback after default handler, No.After to execute before (default)
