详细描述

Categories are used to search for places based on the categories they are associated with. The list/tree of available categories can be obtained from QPlaceManager 。 QPlaceSearchRequest::setCategories () function can be used to limit the search results to places with the specified categories.

若 QGeoServiceProvider supports it, categories can be created and removed. This functionality is available in the QPlaceManager 类。
