overview = """\
+This example demonstrates the ListCtrl's Virtual List features. A Virtual list
+can contain any number of cells, but data is not loaded into the control itself.
+It is loaded on demand via virtual methods <code>OnGetItemText(), OnGetItemImage()</code>,
+and <code>OnGetItemAttr()</code>. This greatly reduces the amount of memory required
+without limiting what can be done with the list control itself.
