javax.swing.LayoutFocusTraversalPolicy
A SortingFocusTraversalPolicy which sorts Components based on their size, position, and orientation. Based on their size and position, Components are roughly categorized into rows and columns. For a Container with horizontal orientation, columns run left-to-right or right-to-left, and rows run top- to-bottom. For a Container with vertical orientation, columns run top-to- bottom and rows run left-to-right or right-to-left. See ComponentOrientation for more information. All columns in a row are fully traversed before proceeding to the next row.

Constructor. Constructs a LayoutFocusTraversalPolicy.
get-component-afterclj
(get-component-after this a-container a-component)Returns the Component that should receive the focus after aComponent. aContainer must be a focus cycle root of aComponent.
By default, LayoutFocusTraversalPolicy implicitly transfers focus down- cycle. That is, during normal focus traversal, the Component traversed after a focus cycle root will be the focus-cycle-root's default Component to focus. This behavior can be disabled using the setImplicitDownCycleTraversal method.
If aContainer is focus traversal policy provider, the focus is always transferred down-cycle.

a-component - a (possibly indirect) child of aContainer, or aContainer itself - java.awt.Component
returns: the Component that should receive the focus after aComponent, or
null if no suitable Component can be found - java.awt.Component
throws: java.lang.IllegalArgumentException - if aContainer is not a focus cycle root of aComponent or a focus traversal policy provider, or if either aContainer or aComponent is null
Returns the Component that should receive the focus after aComponent.
