Alas, I was not able to use or find findBlockByLineNumber. May  be my workaround 
is not that bad. Given a plain Python program solver.py, the call from PyQt 
Gui with data in a textEdit window, might look as follows:

    def solveStructure(self):
        document = self.textEdit.toPlainText()
        document = unicode(document)
        doc = document.split('\n')
	solver(doc)

I thought that there may be a simple way to access the data in a textEdit line 
by line, as it is possible in Delphi (which I used to use before I "saw the 
light" and was converted to Linux and Python).

in the above an i-th line of doc can be accessed by "solver" as doc[i]. 

Pete, though I was not able to find the findBlockByLineNumber, thank you for 
giving me the information.  Greatly appreciated!
