Hi,

Following a bug report on Spyder (PKA Pydee, the Scientific PYthon Development EnviRonment), I've just wrote a simple test with PyQt4 and QScintilla:
http://spyderlib.googlecode.com/files/qscitest.py

This simple test shows two things (maybe bugs?):
1. QScintilla widget is very slow when writing long lines (it gets better when wrapping is turned on, but it's still far slower than its wxPython counterpart) 2. when a long line is written, horizontal scroll does not allow to see the end of the line... that is quite disappointing.

So my questions are:
a. Are these issues known bugs?
b. Is there a way to improve performance without switching to QTextEdit...?

Thanks for your help,
Pierre
