Hi,
In addition to the path described inmy previous question, I also try to follow this path:
1: Access all layers from the map in use:
Layers = myGisMap.getLayers();
2: find the political area at the center of the myGisMap:
politicalArea = layers[0].findPoliticalArea(map.getCenterLongitude(), map.getCenterLatitude());
3: get a OMGeometryList
oMGeometryList = politicalArea.getGeometry();
4: get a geometry
oMGeometry = oMGeometryList.getAt(0);
I do get a geometry and when I run "traceln(oMGeometryList.getDescription());" I find something like
"OMGraphicList with 95 OMGraphics
|--> OMGraphicList with 1 OMGraphic
|--> OMPoly
|--> OMGraphicList with 1 OMGraphic
|--> OMPoly "
This list is actually much longer, showing 95 OMGraphics with 153 OMPolys. So there appears to be something in the oMGeometryList.
However, when I want to extract an OMGeometry from it using "oMGeometry = oMGeometryList.getAt(0);" this oMGeomtry-object has NULL-attributes.
Also, in the API. It says about OMGeometry that "geometry classes are intended to pull the object location data out of the OMGraphics.". This is what I want, but how?
In principle, I just want to query the shp-file if a certain lat/lon is within any shapes/features etc.
Again, I am very interested in any pointers, thanks a lot in advance
cheers
