class TGTextView: public TGView


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.
