Package Summary Overview Summary

### class:GroupLayout.Group [NONE]
- Direct Known Subclasses: GroupLayout.ParallelGroup, GroupLayout.SequentialGroup Enclosing class: GroupLayout
      public abstract class GroupLayout.Group
      extends Object
  `Group` provides the basis for the two types of operations supported by `GroupLayout`: laying out components one after another (`SequentialGroup`) or aligned (`ParallelGroup`). `Group` and its subclasses have no public constructor; to create one use one of `createSequentialGroup` or `createParallelGroup`. Additionally, taking a `Group` created from one `GroupLayout` and using it with another will produce undefined results. Various methods in `Group` and its subclasses allow you to explicitly specify the range. The arguments to these methods can take two forms, either a value greater than or equal to 0, or one of `DEFAULT_SIZE` or `PREFERRED_SIZE`. A value greater than or equal to `0` indicates a specific size. `DEFAULT_SIZE` indicates the corresponding size from the component should be used. For example, if `DEFAULT_SIZE` is passed as the minimum size argument, the minimum size is obtained from invoking `getMinimumSize` on the component. Likewise, `PREFERRED_SIZE` indicates the value from `getPreferredSize` should be used. The following example adds `myComponent` to `group` with specific values for the range. That is, the minimum is explicitly specified as 100, preferred as 200, and maximum as 300.
         group.addComponent(myComponent, 100, 200, 300);
  The following example adds `myComponent` to `group` using a combination of the forms. The minimum size is forced to be the same as the preferred size, the preferred size is determined by using `myComponent.getPreferredSize` and the maximum is determined by invoking `getMaximumSize` on the component.
         group.addComponent(myComponent, GroupLayout.PREFERRED_SIZE,
                   GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE);
Unless otherwise specified all the methods of `Group` and its subclasses that allow you to specify a range throw an `IllegalArgumentException` if passed an invalid range. An invalid range is one in which any of the values are < 0 and not one of `PREFERRED_SIZE` or `DEFAULT_SIZE`, or the following is not met (for specific values): `min` <= `pref` <= `max`. Similarly any methods that take a `Component` throw a `IllegalArgumentException` if passed `null` and any methods that take a `Group` throw an `NullPointerException` if passed `null`. Since: 1.6 See Also: `GroupLayout.createSequentialGroup()`, `GroupLayout.createParallelGroup()`
