OEGetNearbyAtom¶

OEDepict::OENearestAtom OEGetNearbyAtom(const OE2DActiveSiteDisplay &disp,
                  const OEDepict::OE2DPoint &point, double radiusscale=1.0)

Returns an OENearestAtom object that stores a pointer of the atom which is depicted nearest to a given 2D display coordinates. By default, only atoms that not further than half bond away from the given point will be considered.

disp: The OE2DActiveSiteDisplay object of which atoms are being considered.
point: Specifies the 2D display coordinates.
radiusscale: The multiplier that can be used to increase or to decrease the radius around the given point to be considered. This value has to be in a range of \([0.25, 2.0]\).

Note

If there is no atom close to the given display coordinates, then the OENearestBond.IsValid method returns false.
