Signal Details

The "font-set" signal

The ::font-set signal is emitted when the user selects a font. When handling this signal, use gtk_font_button_get_font_name() 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-name signal.

widget :

the object which received the signal.

user_data :

user data set when the signal handler was connected.

Since 2.4
