65 * @See_also: #GtkFontSelectionDialog, #GtkFontChooser
67 * The #GtkFontSelection widget lists the available fonts, styles and sizes,

72 * To set the font which is initially selected, use
73 * gtk_font_selection_set_font_name().
75 * To get the selected font use gtk_font_selection_get_font_name().
77 * To change the text which is shown in the preview area, use
78 * gtk_font_selection_set_preview_text().
