    • getFont

      @Deprecated public Str getFont()
      Veraltet.
      Gets the currently-selected font name.

      Note that this can be a different string than what you set with
      [method@Gtk.FontChooser.set_font], as the font chooser widget may
      normalize font names and thus return a string with a different
      structure. For example, “Helvetica Italic Bold 12” could be
      normalized to “Helvetica Bold Italic 12”.

      Use [method@Pango.FontDescription.equal] if you want to compare two
      font descriptions.

      A string with the name of the current font

      FcConfig *config;
      PangoFontMap *fontmap;

      config = FcInitLoadConfigAndFonts ();
      FcConfigAppFontAddFile (config, my_app_font_file);

      Note that other GTK widgets will only be able to use the
      application-specific font if it is present in the font map they use:

      ```c
      context = gtk_widget_get_pango_context (label);
