// A list view is a widget that can contain a number of items //

// by a string or by an icon. //
// //
// The TGListView is user callable. The other classes are service //
// classes of the list view. //
// //
// A list view can generate the following events: //
// kC_CONTAINER, kCT_SELCHANGED, total items, selected items. //
// kC_CONTAINER, kCT_ITEMCLICK, which button, location (y<<16|x). //
// kC_CONTAINER, kCT_ITEMDBLCLICK, which button, location (y<<16|x). //
