To determine if the * cell actually contains the specified location, compare the point against * the cell's bounds, as provided by {@code getCellBounds}. * This method returns {@code -1} if the list's model is empty. * @param location the coordinates of the point * @return the cell index closest to the given location, or {@code -1} * @throws NullPointerException if {@code location} is null * Returns the origin in the given {@code JList}, of the specified item, * in the list's coordinate system. * Returns {@code null} if the index isn't valid. * @param index the cell index * @return the origin of the cell, or {@code null} * Returns the bounding rectangle, in the given list's coordinate system, * for the range of cells specified by the two indices. * The indices can be supplied in any order. * If the smaller index is outside the list's range of cells, this method * returns {@code null}. If the smaller index is valid, but the larger * index is outside the list's range, the bounds of just the first index * is returned. Otherwise, the bounds of the valid range is returned. * @param index1 the first index in the range * @param index2 the second index in the range * @return the bounding rectangle for the range of cells, or {@code null}
