* @Short_description: A dialog box for selecting fonts
* @Title: GtkFontChooserDialog
* @See_also: #GtkFontChooser, #GtkDialog
*
* The #GtkFontChooserDialog widget is a dialog box for selecting a font.
*
* To set the font which is initially selected, use
* gtk_font_chooser_dialog_set_font_name().
*
* To get the selected font use gtk_font_chooser_dialog_get_font_name().
*
* To change the text which is shown in the preview area, use
* gtk_font_chooser_dialog_set_preview_text().
*
* <refsect2 id="GtkFontChooserDialog-BUILDER-UI">
* <title>GtkFontChooserDialog as GtkBuildable</title>
* The GtkFontChooserDialog implementation of the GtkBuildable interface
* exposes the embedded #GtkFontChooser as internal child with the
* name "font_chooser". It also exposes the buttons with the names
* "select_button" and "cancel_button.
* </refsect2>
*
* Since: 3.2
