a pleasant user experience. Similar to Java Swing, JavaFX layout has stock layouts that
provide the most common ways to display UI controls on the scene graph. This recipe
demonstrates the

class.
Recall Recipe 14-4, in which you implemented a custom layout to display compon-
ents in a grid-like manner. You may notice similarities, but we left a lot of implementa-
