Class Description

                                                                      
 TGText                                                               
                                                                      
 A TGText is a multi line text buffer. It allows the text to be       
 loaded from file, saved to file and edited. It is used in the        
 TGTextEdit widget. Single line text is handled by TGTextBuffer       
 and the TGTextEntry widget.

void DelText(ULong_t pos, ULong_t length)
 Delete length chars from line starting at position pos.

void InsText(ULong_t pos, const char *text)
 Insert text in line starting at position pos.

char* GetText(ULong_t pos, ULong_t length)

void DelChar(ULong_t pos)
 Delete a character from the line.

 Insert a character at the specified position.

char GetChar(ULong_t pos)
 Get a character at the specified position from the line.
