<p>
The ::font-set signal is emitted when the user selects a font. 
When handling this signal, use <a class="link" href="GtkFontButton.html#gtk-font-button-get-font-name"><code class="function">gtk_font_button_get_font_name()</code></a> 
to find out which font was just selected.
</p>
<p>
Note that this signal is only emitted when the <span class="emphasis"><em>user</em></span>
changes the font. If you need to react to programmatic font changes
as well, use the notify::font-name signal.</p>
