25 // TGListView, TGLVContainer and TGLVEntry //
26 // //
27 // A list view is a widget that can contain a number of items //
28 // arranged in a grid or list. The items can be represented either //
29 // by a string or by an icon. //
30 // //
31 // The TGListView is user callable. The other classes are service //
32 // classes of the list view. //
33 // //
34 // A list view can generate the following events: //
35 // kC_CONTAINER, kCT_SELCHANGED, total items, selected items. //
36 // kC_CONTAINER, kCT_ITEMCLICK, which button, location (y<<16|x). //
37 // kC_CONTAINER, kCT_ITEMDBLCLICK, which button, location (y<<16|x). //
38 // //
