Interface SimplifiedFocusTraversalPolicy

All Known Implementing Classes:

CombinedStackDockFocusTraversalPolicy, DisplayerFocusTraversalPolicy

public interface SimplifiedFocusTraversalPolicy

An interface which mimics the behavior of FocusTraversalPolicy but implementing classes are not required to respect any other focus cycle roots, policy providers or visibility, focusability, displayability nor the enabled state. This SimplifiedFocusTraversalPolicy will be put into a DockFocusTraversalPolicy which will handle all these issues.
