This field is used when the component is smaller than its display area. It determines where, within the area, to place the component. Valid values are the following:

The default value is GridBagConstraints.CENTER.

This field is used when the component's display area is larger than the component's requested size. It determine whether to resize the component, and if so, how.

Valid values are the following:

• GridBagConstraint.NONE:Do not resize the component.

• GridBagConstraint.HORIZONTAL: Make the component wide enough to fill its display area horizontally, but don't change its height.
• GridBagConstraint.VERTICAL: Make the component tall enough to fill its display area vertically, but don't change its width.
• GridBagConstraint.BOTH: Make the component fill its display area entirely.

The default value is GridBagConstraint.NONE.

Specifies the number of cells in a column for the component's display area.

Use GridBagConstraints.REMAINDER to specify that the component be the last one in its column. Use GridBagConstraints.RELATIVE to specify that the component be the next to last one in its column.

The default value is 1.

Specifies the number of cells in a row for the the component's display area.

Use GridBagConstraints.REMAINDER to specify that the component be the last one in its row. Use GridBagConstraints.RELATIVE to specify that the component be the next to last one in its row.

The default value is 1.

Specifies the cell at the left of the component's display area, where the leftmost cell has gridx = 0. The value GridBagConstraints.RELATIVE specifies that the component be placed just to the right of the component that was added to the container just before this component was added.

The default value is GridBagConstraints.Relative.

Specifies the cell at the top of the component's display area, where the topmost cell has gridy = 0. The value GridBagConstraints.RELATIVE specifies that the component be placed just below the component that was added to the container just before this component was added.

The default value is GridBagConstraints.Relative.

This field specifies the external padding of the component, the minimum amount of space between the component and the edges of its display area.

The default value is new Insets(0, 0, 0, 0);

This field specifies the internal padding, that is how much space to add to the minimum size of the component. The width of the component is at least its minimum width plus ipadx*2 pixels.

The default value is 0.

This field specifies the internal padding, how much to add to the minimum size of the component. The height of the component is at least its minimum height plus ipadx*2 pixels.

The default value is 0.

This field specifies how to distribute extra vertical space.

The grid bag layout manager calculates the weight of a row to be the maximum weightx of all the components in a row. If the resulting layout is smaller vertically than the area it needs to fill, the extra space is distributed to each row in proportion to its weight. A row that has weight 0 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.

The default value of this field is zero.

This field specified 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 weight 0 receives no extra space.

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

The default value of this field is zero.

Put the component in the center of its display area.

Put the component on the right side of its display area, centered vertically.

Put the component in the top of its display area, centered horizontally

Put the component in the top right corner of its display area.

Put the component in the top left corner of its display area.

Put the component in the bottom of its display area, centered horizontally

Put the component in the bottom right corner of its display area.

Put the component in the bottom left corner of its display area.

Put the component on the left side of its display area, centered vertically.

Resize the component both horizontally and vertically.

Resize the component horizontally but not vertically.

Do not resize the component.

Resize the component vertically but not horizontally.

Specify that the component is the last component in its column or row.

Specify that this component is the next to last component in its column or row (gridwidth, gridheight), or that this component be placed next to the previously added component (gridx, gridy).

Creates a grid bag constraint object with all the fields set to their default value.

Returns:

a copy of this grid bag constraint.

Overrides:

clone in class Object (I-§1.12.2).
