firstLine

Component firstLine
A relative positioning constant, that can be used instead of north, south, east, west or center. mixing the two types of constants can lead to unpredicable results. If you use both types, the relative constants will take precedence. For example, if you add components using both the NORTH and BEFORE_FIRST_LINE constants in a container whose orientation is LEFT_TO_RIGHT, only the BEFORE_FIRST_LINE will be layed out. This will be the same for lastLine, firstItem, lastItem.

weightx

double weightx
Specifies how to distribute extra horizontal space.

The grid bag layout manager calculates the weight of a column to be the maximum weighty of all the components in a row. If the resulting layout is smaller horizontally than the area it needs to fill, the extra space is distributed to each column in proportion to its weight. A column that has a weight zero receives no extra space.

If all the weights are zero, all the extra space appears between the grids of the cell and the left and right edges.

The default value of this field is 0. weightx should be a non-negative value.

A row that has a weight of zero receives no extra space.

If all the weights are zero, all the extra space appears between the grids of the cell and the top and bottom edges.

Serialized Fields

columnWeights

double[] columnWeights
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] > then 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.
See Also:
