I am afraid I am not competent to help you much further, because of my lack of 
knowledge of PyQt.  I do use textEdit as one main QWidget for a GUI of an 
extant Python program which I am writing, but not two textEdit's at a time.

Actually, I would like to know if it is possible to extract one line of text 
from textEdit, so I pay closer attention to questions about textEdit. Do you 
know if it can be done and if so how?

It seems that for my GUI, two textEdits could possibly be useful  - one for 
data input and one for output.  I thought of using tab widgets - each tab with 
a single textEdit for that purpose.  Just tried it out a minute ago in "Qt 
Designer".  It looks promising.

Perhaps it would be helpful to try your ideas of set out with Qt Designer?

May be you should raise the question again in a new thread as I spoiled this 
thread for you with my "cheap answer" - sorry about that!
