Include in filter
Each of these flags may have the modifier
SIS_OPENBRANCHadded to them in order to open a class tree branch in readiness for modifying the filter behaviour of a sub-class of the Item class specified in the aclass argument.
- The property clause, e.g.
The Item class name in the aclass argument (which reflects the Cadcorp SIS 9.0 C++ class name) is not necessarily the same that appears in the SIS user interface, which is translatable.
In particular the "Polygon" and "TopoLineString" item classes should be specified as "SeedArea" and "SeedChain" respectively. The class name to use in this method is stored in the Class name item property. The translatable class name is stored in the Item class property.
