python - Publishing geospatial data with Plone -

-

i setting new site on plone using collective.geo.bundle, need make data accessible desktop gis. 2 obvious ways of doing use postgres/postgis database, or publish data through wfs service. problem appears plone stores pickles in database, gis wouldn't able make sense of data, , there doesn't seem addon exposes wfs. 2 questions then:

  1. is there way use configure plone use postgres/postgis database geometry data types, data can read outside plone?

  2. is there way set plone (e.g. through addon) expose wfs?

tl;dr: don't think there out-of-the-box solution (using collective.geo.*) this.

as mentioned in comments, plone doesn't deal geospatial data @ all, it's collective.geo.geographer this. more specifically, it's georeferencingannotator saves coordinates igeoreferenceable objects annotations (and loads them there).

so, forcing plone store content in relational db, example using relstorage wont - plone or relstorage don't know geospatial data, , store annotations other.

however, shouldn't too hard write own iwritegeoreferenced adapter writes georeferencing data postgis database instead of annotations, using uuid of context link data objects, , maybe store additional metadata title or url. georeferencing data separate actual content - there's no need put plone content postgresql db.

a different approach write event handler objectgeoreferencedevent, , publish georeferencing data postgis db (in addition having stored in annotations on actual objects). since want access read-only desktop gis, wouldn't have worry syncing data in both directions.

last not least, suggest have @ collective.geo mailing list - people on there responsive , helpful, , imagine else had same use case.

python - Subclassed QStyledItemDelegate ignores Stylesheet -

i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here
