Gtk.Label.prototype.get_attributes

function get_attributes():Pango.AttrList {
    // Gjs wrapper for gtk_label_get_attributes()
}

Gets the attribute list that was set on the label using Gtk.set_attributes, if any. This function does not reflect attributes that come from the labels markup (see Gtk.set_markup). If you want to get the effective attributes for the label, use pango_layout_get_attribute (gtk_label_get_layout (label)).
