[PyQt] ANN: Preview of Python code editor widget - pure Python alternative to QScintilla

[Benoît HERVIER]

Hi Algis,

Bracket aren't automatically closed, but are just highlighted, space
after comma isn't added automatically too (but thanks for the idea).
Auto indent after a line ending with a ':' should work (At least it s
works for me).

Or perhaps i've made enought test to made it work on other plateform
than Maemo :)

KhtEditor target Maemo and MeeGo device so small screen and low cpu power.

Indeed, for the moment the prerequisites are assumed by the maemo
debian package.

But i'll take a look at the Henning's classes.
