within a certain distance of a reference geometry
E.g. this request will retrieve all features within 50 map units of the
provided linestring:
QgsFeatureRequest().setDistanceWithin(QgsGeometry.fromWkt('LineString(0 0, 10 0, 12 1)'), 50)
A new enum Qgis::SpatialFilterType has been added to reflect whether
a request uses no spatial filter, a BoundingBox filter (via
setFilterRect), or the new DistanceWithin filter.
Distance within filters are treated like bounding box filters, in
that they are independant of any attribute/id filters (such as
feature ids or expressions).
items should be automatically monitored for changes
This monitoring can be expensive for some locations (eg network
folders or cloud based directories), so in these cases it is
desirable to allow it to be disabled to avoid hangs in the QGIS
application.
keyword in Python, so this value was previously inaccessible to PyQGIS
scripts
Also change all references to Qgis::MessageLevel values to their
fully qualified names, to ease a future transition to an enum
class (when sip bugs are fixed)
Fixes#42996
should use symbol levels whenever that symbol is used by the renderer
Not exposed to users -- only settable via API, but IS saved in the
symbol's XML definition and restored when loading a symbol from XML.
class
This avoids an ugly include of qgsvectorlayerexporter.h in
qgsproviderregistry.h/qgsprovidermetadata.h, which in turn
triggers an inclusion of qgsvectorlayer.h and a bunch of
other heavy dependencies.
- Add enums to qgis.h instead of qgscoreenums, so that they belong to
a Qgis namespace
- Split up the various symbol headers into multiple files so that we
can fine-tune their inclusion and forward declare more readily, speeding
up recompilation
- Move QgsSymbol enums to qgis
there is an issue in SIP when mixing non-scoped and scoped enums in the same class
see https://www.riverbankcomputing.com/hg/sip/rev/ccc4eda868de
and if switching all to scoped enum, there is a conversion issue in slot
for MessageLevel (whhen connection QgsMessageLog::messageReceived)
