Describes the parts of a geometry that can be located by their proximity to a query point. Specified as a parameter to the HitTest method.
| Constant | Value | Description |
|---|---|---|
| esriGeometryPartNone | 0 | Not used. |
| esriGeometryPartVertex | 1 | Locates a vertex of the geometry closest to the query point. |
| esriGeometryPartBoundary | 4 | Locates a point anywhere on the boundary of a polygon, or anywhere on a polyline, that is closest to the query point. |
| esriGeometryPartMidpoint | 8 | Locates a midpoint of a segment belonging to a polygon or polyline that is closest to the query point. |
| esriGeometryPartCentroid | 32 | Locates the geometric centroid of a polygon or the center of an envelope closest to the query point. |
| esriGeometryPartEndpoint | 16 | Locates an endpoint of the polyline closest to the query point. |
| esriGeometryPartSurface | 64 | Locates a point anywhere on the surface of a polygon or multipatch that is closest to the query ray. |
