getIndexAtPoint</H3>
<PRE>
public int <B>getIndexAtPoint</B>(<A HREF="../../java/awt/Point.html">Point</A>&nbsp;p)</PRE>
<DL>
<DD>Given a point in local coordinates, return the zero-based index
 of the character under that Point.  If the point is invalid,
 this method returns -1.

 Note: the AbstractButton must have a valid size (e.g. have
 been added to a parent container whose ancestor container
 is a valid top-level window) for this method to be able
 to return a meaningful value.<DD><DL>
