[Interest] Custom user attributes for QGeoPositionInfo

[Blasche Alexander]

Hi,

I'd like to hear more about the use case. Taking heart rate and associating it to a positioninfo object sounds a bit strange. For example you might get heart rate update at a much faster rate than position updates or vice versa. This means you'd loose the contingency of at least one set of data.

Even if you don't care about this couldn't you simply use your own data type which would have a position attribute and a heart rate attribute?

I guess not. As it doesn't inherit QObject you also can't add dynamic
properties at runtime.

Might make sense to add in future release. Could be implemented with
UserAttribute and internal QVariantMap or something similar.
