Class Description

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

 Create a listbox.

 Delete a listbox widget.

 initiate the internal classes of a list box

 Draw borders of the list box widget.

 Add entry with specified string and id to listbox. The id will be
 used in the event processing routine when the item is selected.
 The string will be adopted by the listbox.

 Add entry with specified string and id to listbox. The id will be
 used in the event processing routine when the item is selected.

 Add specified TGLBEntry and TGLayoutHints to listbox. The
 entry and layout will be adopted and later deleted by the listbox.

 Add entry with specified string and id to listbox sorted by increasing id.
 This sorting works proberly only if EntrySort functions are used to add
 entries without mixing them with other add or insert functions.  The id will be
 used in the event processing routine when the item is selected.
 The string will be adopted by the listbox.

 Add entry with specified string and id to listbox sorted by increasing id.
 This sorting works proberly only if EntrySort functions are used to add
 entries without mixing them with other add or insert functions. The id will be
 used in the event processing routine when the item is selected.

 Add specified TGLBEntry and TGLayoutHints to listbox sorted by increasing id.
 This sorting works proberly only if EntrySort functions are used to add
 entries without mixing them with other add or insert functions. The
 entry and layout will be adopted and later deleted by the listbox.

 Insert entry with specified string and id behind the entry with afterID.
 The string will be adopted and later deleted by the listbox.

 Insert entry with specified string and id behind the entry with afterID.

 Insert the specified TGLBEntry and layout hints behind afterID.
 The entry and layout will be adopted and later deleted by the listbox.

 Scroll the entry with id to the top of the listbox.

 Resize the listbox widget. If fIntegralHeight is true make the height
 an integral number of the maximum height of a single entry.

 Move and resize the listbox widget.

 Return default size of listbox widget.

 Layout the listbox components.

 Return id of selected listbox item.

 Adds all selected entries (TGLBEntry) of the list box into
 the list selected.

 Process messages generated by the listbox container and forward
 messages to the listbox message handling window.

 Emit signal with list box id and entry id.

 Save a list box widget as a C++ statement(s) on output stream out.
