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.

TGTextLBEntry(const TGWindow *p, TGString *s, Int_t id, GContext_t norm, FontStruct_t font, UInt_t options, ULong_t back) : TGLBEntry(p, id, options, back)

 Create a text listbox entry. The TGString is adopted.

~TGTextLBEntry()

 Delete text listbox entry.

void DoRedraw()

 Redraw text listbox entry.

void SetText(TGString *new_text)

 Set or change text in text entry.
