 A TGTextView displays a file or a text buffer in a frame with a      
 vertical scrollbar. Internally it uses a TGTextFrame which displays  
 the text.

TGTextFrame(TGWindow *parent, UInt_t w, UInt_t h, UInt_t options, ULong_t back) : TGFrame(parent, w, h, options, back)

 Create a text frame.

~TGTextFrame()

 Delete a text frame object.

void Expand(Int_t newSize)

 Expand or shrink lines container to newSize.

void Clear(Option_t *)

 Clear text frame.

Bool_t LoadFile(const char *filename)

 Load file into text frame.

Bool_t LoadBuffer(const char *txtbuf)

 Load 0 terminated txtbuf buffer into text frame.

void DrawRegion(Int_t x, Int_t y, UInt_t w, UInt_t h)

 Draw lines in exposed region.

void SetTopLine(Int_t new_top)

 Set new top line.

void ScrollWindow(Int_t new_top)

 Scrollwindow to make new_top the first line being displayed.
