Tkinter Text widget getting too slow

[Neil Hodgson]

John J. Lee:

> How about something like Scintilla?

   The original poster had tried PyCrust which uses the wxWindows port of
Scintilla wxStyledTextCtrl. The design centre for Scintilla is editing
source code files and its assumptions are incorrect for very large documents
or very wide documents. The performance of Scintilla is dependent on how it
is used as much as its design and it can be sped up greatly by turning off
styling and word wrap.
