/**

|
Controls the order in which keyboard focus moves between components.
|
|
|
|
The default behaviour of this class uses a FocusTraverser object internally to
|
|
determine the default/next/previous component until it finds one which wants
|
|
keyboard focus, as set by the Component::setWantsKeyboardFocus() method.
|
|
|
|
If you need keyboard focus traversal in a more customised way, you can create
|
|
a subclass of ComponentTraverser that uses your own algorithm, and use
|
|
Component::createKeyboardFocusTraverser() to create it.
