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.                                          
                                                                      

 Common initialization method.

 Create default (empty) text buffer.

 Create text buffer and initialize with other text buffer.

 Create text buffer and initialize with single line string.

 Destroy text buffer.

 Clear text buffer.

 Load text from file fn. Startpos is the begin from where to
 load the file and length is the number of characters to read
 from the file.

 Load a 0 terminated buffer. Lines will be split at '\n'.

 Save text buffer to file fn.

 Append buffer to file fn.

 Delete character at specified position pos.

 Insert character c at the specified position pos.

 Get character a position pos. If charcater not valid return -1.

 Delete text between start and end positions. Returns false in
 case of failure (start and end not being within bounds).

 Insert src text from start_src to end_src into text at position ins_pos.
 Returns false in case of failure (start_src, end_src out of range for
 src, and ins_pos out of range for this).

 Insert single line at specified position. Return false in case position
 is out of bounds.

 Add another text buffer to this buffer.

 Insert string before specified position.
 Returns false if insertion failed.

 Delete specified row. Returns false if row does not exist.

 Return string at position pos. Returns 0 in case pos is not valid.
 The returned string must be deleted by the user.

 Break line at position pos. Returns false if pos is not valid.

 Get length of specified line. Returns -1 if row does not exist.

 Make specified row the current row. Returns false if row does not exist.
 In which case fCurrent is not changed or set to the last valid line.

 Redo all tabs in a line. Needed after a new tab is inserted.

 Search for string searchString starting at the specified position going
 in forward (direction = true) or backward direction. Returns true if
 found and foundPos is set accordingly.

 Replace oldText by newText. Returns false if nothing replaced.

 Set fLongestLine.
