Group: QPlaceAttribute is part of QtLocation-places, QtLocation-places-data
Detailed Description▲
A QPlaceAttribute instance stores an additional piece of information about a place that is not otherwise exposed through the QPlace class. A QPlaceAttribute encapsulates a localized label which describes the attribute and rich text string representing the attribute's value. Generally, both are intended to be displayed to the end-user as is.
Some plugins may not support attributes at all, others may only support a certain set, others still may support a dynamically changing set of attributes over time or even allow attributes to be arbitrarily defined by the client application. The attributes could also vary on a place by place basis, for example one place may have opening hours while another does not. Consult the plugin references for details.
Attribute Types▲
The QPlaceAttribute class defines some constant strings which characterize standard attribute types.
There is a class of attribute types of the format x_id_<provider> for example x_id_here. This class of attributes is a set of alternative identifiers of the place, from the specified provider's perspective.
The above types are used to access and modify attributes in QPlace via:
The attribute type is a string type so that providers are able to introduce new attributes as necessary. Custom attribute types should always be prefixed by a qualifier in order to avoid conflicts.
User Readable and Non-User Readable Attributes▲
Some attributes may not be intended to be readable by end users, the label field of such attributes are empty to indicate this fact.
