TGListView Class Reference

A list view is a widget that can contain a number of items arranged in a grid or list.

The items can be represented either 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).
