18// TGListBox, TGLBContainer, TGLBEntry and TGTextLBEntry //
19// //
20// A listbox is a box, possibly with scrollbar, containing entries. //
21// Currently entries are simple text strings (TGTextLBEntry). //
22// A TGListBox looks a lot like a TGCanvas. It has a TGViewPort //
23// containing a TGLBContainer which contains the entries and it also //
24// has a vertical scrollbar which becomes visible if there are more //
25// items than fit in the visible part of the container. //
26// //
27// The TGListBox is user callable. The other classes are service //
28// classes of the listbox. //
29// //
30// Selecting an item in the listbox will generate the event: //
31// kC_COMMAND, kCM_LISTBOX, listbox id, item id. //
32// //
