## Class Description

     TGView

     A TGView provides the infrastructure for text viewer and editor
     widgets. It provides a canvas (TGViewFrame) and (optionally) a
     vertical and horizontal scrollbar and methods for marking and
     scrolling.

     The TGView (and derivatives) will generate the following
     event messages:
     kC_TEXTVIEW, kTXT_ISMARKED, widget id, [true|false]
     kC_TEXTVIEW, kTXT_DATACHANGE, widget id, 0
     kC_TEXTVIEW, kTXT_CLICK2, widget id, position (y << 16) | x)
     kC_TEXTVIEW, kTXT_CLICK3, widget id, position (y << 16) | x)
     kC_TEXTVIEW, kTXT_F3, widget id, true
     kC_TEXTVIEW, kTXT_OPEN, widget id, 0
     kC_TEXTVIEW, kTXT_CLOSE, widget id, 0
     kC_TEXTVIEW, kTXT_SAVE, widget id, 0

TGViewFrame(TGView *v, UInt_t w, UInt_t h, UInt_t options, ULong_t back) : TGCompositeFrame(v, w, h, options | kOwnBackground, back)

     Create a editor frame.
