It is only really possible if your find/replace operation can be
cancelled.  What is more likely than not is that your find/replace is
occurring in the same thread as all of your GUI handling code; and this
is likely going to be the case if you are finding/replacing inside some
text control.

What I have personally done in PyPE is to only find/replace up to 10
items at a time, then use wx.FutureCall(1, ...) to schedule another call
to handle 10 more items in 1 ms.  This allows the GUI to be redrawn, etc.

Alternatively, in the find case, I have put a call to wx.Yield() in the
main loop of a 'find all' command, and checked the status of a button
that determines whether the search should stop or not.

The details of each of these are in findbar.py and findinfiles.py inside
the PyPE source distribution available from http://pype.sf.net .
