e611. Setting Focus Traversal Keys for the Entire ApplicationThis example changes the focus traversal keys for the entire application. For an example of how to change the focus traversal keys for a particular component, see e610 Setting Focus Traversal Keys in a Component.// Change the forward focus traversal keys for the application Set set = new HashSet( KeyboardFocusManager.getCurrentKeyboardFocusManager().getDefaultFocusTraversalKeys( KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS)); set.clear(); // Call clear() if you want to eliminate the current key set set.add(KeyStroke.getKeyStroke("F2")); KeyboardFocusManager.getCurrentKeyboardFocusManager().setDefaultFocusTraversalKeys( KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, set); // Change the backward focus traversal keys for the application set = new HashSet( KeyboardFocusManager.getCurrentKeyboardFocusManager().getDefaultFocusTraversalKeys( KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS)); set.clear(); // Call clear() if you want to eliminate the current key set set.add(KeyStroke.getKeyStroke("F3")); KeyboardFocusManager.getCurrentKeyboardFocusManager().setDefaultFocusTraversalKeys( KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS, set); // Remove all forward and backward focus traversal keys for the application set.clear(); KeyboardFocusManager.getCurrentKeyboardFocusManager().setDefaultFocusTraversalKeys( KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, set); KeyboardFocusManager.getCurrentKeyboardFocusManager().setDefaultFocusTraversalKeys( KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS, set);
