Class Description

                                                                      
 TGTextView                                                           
                                                                      
 A TGTextView is a text viewer widget. It is a specialization of      
 TGView. It uses the TGText class (which contains all text            
 manipulation code, i.e. loading a file in memory, changing,          
 removing lines, etc.). Use a TGTextView to view non-editable text.   
 For supported messages see TGView.
