```
public final class RowLayoutFactory
extends Object
```
RowLayoutFactory creates and initializes row layouts. There are two ways to use RowLayoutFactory. Normally, it is used as a shorthand for writing "new RowLayout()" and initializing a bunch of fields. In this case the main benefit is a more concise syntax and the ability to create more than one identical RowLayout from the same factory. Changing a property of the factory will affect future layouts created by the factory, but has no effect on layouts that have already been created.
