- * GtkEntryBuffer provides the text content in a GtkEntry.
- * Applications can provide their own buffer implementation,
- * e.g. to provide secure handling for passwords in memory.
+ * GtkEntry can provide basic Undo/Redo support using standard keyboard

+/* Lists/Weather
+ *
+ * This demo shows a few of the rarer features of GtkListView and
+ * how they can be used to display weather information.
+ *
+ * The hourly weather info uses a horizontal listview. This is easy
+ * to achieve because GtkListView implements the GtkOrientable interface.
+ * To make the items in the list stand out more, the listview uses
+ * separators.
+ *
+ * A GtkNoSelectionModel is used to make sure no item in the list can be
+ * selected. All other interactions with the items is still possible.
+ *
+ * The dataset used here has 70000 items.
