Class CustomFocusTraversalPolicy

  • All Implemented Interfaces:
    java.io.Serializable
    public final class CustomFocusTraversalPolicy
extends javax.swing.LayoutFocusTraversalPolicy
    This class creates a custom focus policy for Swing components by extending LayoutFocusTraversalPolicy. The focus policy is based upon an array of components. These components are focused as they are placed in the array: array[0] --> array[1] --> ... ---> array[last] ---> array[0] Only components in the array are focused, all other components only gain focus if you place the mouse pointer inside. This is a pretty clean and solid solution to the Swing Focus Issue, at least until Sun provides us with a better one.
