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).
with preset choices in processing GUI
In some circumstances it is desirable to restrict the values available
when a user is asked to enter a string parameter to a list of predetermined
"valid" values, yet these values will vary installation by installation
(e.g. a "printer name" parameter, where you want users to pick from
printers installed on the system, but since the printer names will
vary install to install an enum parameter is not a valid choice)
This can now be done by setting the widget wrapper metadata
"value_hints" option, as demonstrated below. (While this provides a mechanism
for guiding users to select from valid string values when running a Processing
algorithm through the GUI, it does not place any limits on the string values
accepted via PyQGIS codes or when running the algorithm via other non-gui
means. Algorithms should gracefully handle other values accordingly.)
param = QgsProcessingParameterString( 'PRINTER_NAME', 'Printer name')
# show only printers which are available on the current system as options
# for the string input.
param.setMetadata( {'widget_wrapper':
{ 'value_hints': ['Inkjet printer', 'Laser printer'] }
})
