* #GtkMapListModel is a list model that takes a list model and maps the items
* in that model to different items according to a #GtkMapListModelMapFunc.
*
- * FIXME: Add useful examples here, like turning #GFile into #GFileInfo or #GdkPixmap.
+ * Example: Create a list of #GtkEventControllers
+ * |[
+ * static gpointer
+ * map_to_controllers (gpointer widget,
