[Interest] Distance from point to path.

[william.crocker at analog.com]

Hello:

Given a QPoint and a QPainterPath.
How do I find the distance from the QPoint to the
closest point along the QPainterPath.

I could step along the path with pointAtPercent
looking for the closest point, but that seems unduly
expensive: O(100N).

Any better ideas.

Thanks.

Bill

All of the above to find the shape closest to a mouse click.
Note that methods are provided to find the set of objects
which intersect a rectangle centered on the point, but which one
is really the closest?
