Review request for KDE Frameworks and Martin Tobias Holmedahl Sandsmark.


Repository: sonnet


Description
-------

Don't try to highlight if there is no spell checker found

It's slightly wasteful to do a re-highlight, more important without this we max out the CPU usage as rehighlightRequest singleShot is still false (see line 120 in the constructor), so this timer constantly retriggers with no interval.

Testing
-------

ran textedit example without my CPU usage skyrocketing.


Thanks,

David Edmundson
