[Scott Aron Bloom]

That's exactly what I wound up doing... But its clearly not a code less solution :(

Scott,

I'm not certain that all these functions exist in QPlainTextEdit, but I'll tell you how I did it in QTextEdit by subclassing QTextEdit and reimplementing QTextEdit::mouseDoubleClickEvent(QMouseEvent *e). I get the position of the mouse click via e->pos(), and then get a QTextCursor using QTextEdit::cursorForPosition(const QPoint &). At that point you just need to walk backward and forward as far as you want and until you hit whatever word separator you want, and then set the text cursor, or (in my case), use setExtraSelections() to do more complex selections... Hope that helps.

Josh
