# Class GroupLayout.SequentialGroup

java.lang.Object
javax.swing.GroupLayout.Group
javax.swing.GroupLayout.SequentialGroup

Enclosing class:
  `GroupLayout`

public final class GroupLayout.SequentialGroup extends GroupLayout.Group
A `Group` that positions and sizes its elements sequentially, one after another. This class has no public constructor, use the `createSequentialGroup` method to create one.

In order to align a `SequentialGroup` along the baseline of a baseline aligned `ParallelGroup` you need to specify which of the elements of the `SequentialGroup` is used to determine the baseline. The element used to calculate the baseline is specified using one of the `add` methods that take a `boolean`. The last element added with a value of `true` for `useAsBaseline` is used to calculate the baseline.

Since:
  1.6
