OEGetNearbyAtom¶

OENearestAtom OEGetNearbyAtom(const OE2DMolDisplay &disp, const 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 are no further than half bond away from the given point will be considered.

disp: The OE2DMolDisplay object of which atoms are being considered. Only atoms of which atom display is visible are examined (OEAtomDisplayBase::IsVisible)
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 OENearestAtom::IsValid method returns false.
