 does not have gridbag constraints associated with
 it, then the component will be assigned a
 copy of the <code>defaultConstraints</code>.<DD><DL>

<DD>This field holds tha layout information
 for the gridbag.  The information in this field
 is based on the most recent validation of the
 gridbag.
 If <code>layoutInfo</code> is <code>null</code>
 this indicates that there are no components in
 the gridbag or if there are components, they have
 not yet been validated.<DD><DL>

 widths have been calculated.
 If columnWidths has more elements than the number of
 columns, columns are added to the gridbag to match
 the number of elements in columnWidth.<DD><DL>

<DL>
<DD>This field holds the overrides to the column weights.
 If this field is non-null the values are
 applied to the gridbag after all of the columns
 weights have been calculated.
 If columnWeights[i] &gt; weight for column i, then
 column i is assigned the weight in columnWeights[i].
 If columnWeights has more elements than the number
 of columns, the excess elements are ignored - they do
 not cause more columns to be created.</DL>

<DD>This field holds the overrides to the row weights.
 If this field is non-null the values are
 applied to the gridbag after all of the rows
 weights have been calculated.
 If rowWeights[i] &gt; weight for row i, then
 row i is assigned the weight in rowWeights[i].
 If rowWeights has more elements than the number
 of rows, the excess elements are ignored - they do
 not cause more rows to be created.</DL>
