## Class CellConstraints

- java.lang.Object
- - com.jgoodies.forms.layout.CellConstraints

- All Implemented Interfaces:
    Serializable, Cloneable

      public final class CellConstraints
      extends Object
      implements Cloneable, Serializable

  Defines constraints for components that are laid out with the FormLayout. Defines the components display area: grid x, grid y, grid width (column span), grid height (row span), horizontal alignment and vertical alignment.

  Most methods return this object to enable method chaining.

  You can set optional insets in a constructor. This is useful if you need to use a pixel-size insets to align perceived component bounds with pixel data, for example an icon. Anyway, this is rarely used. The insets don't affect the size computation for columns and rows. I consider renaming the insets to offsets to better indicate the motivation for this option.

  Examples:
  The following cell constraints locate a component in the third column of the fifth row; column and row span are 1; the component will be aligned with the column's right-hand side and the row's bottom.

       CellConstraints cc = new CellConstraints();
       cc.xy  (3, 5);
       cc.xy  (3, 5, CellConstraints.RIGHT, CellConstraints.BOTTOM);
       cc.xy  (3, 5, "right, bottom");

       cc.xyw (3, 5, 1);
       cc.xyw (3, 5, 1, CellConstraints.RIGHT, CellConstraints.BOTTOM);
       cc.xyw (3, 5, 1, "right, bottom");

       cc.xywh(3, 5, 1, 1);
       cc.xywh(3, 5, 1, 1, CellConstraints.RIGHT, CellConstraints.BOTTOM);
       cc.xywh(3, 5, 1, 1, "right, bottom");

  See also the examples in the `FormLayout` class comment.

  TODO: Explain in the JavaDocs that the insets are actually offsets. And describe that these offsets are not taken into account when FormLayout computes the column and row sizes.

  TODO: Rename the inset to offsets.
