TGTextView Class Reference

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.
