Method Detail

componentInserted

default void componentInserted(Container container,
                               int index)

Called when a component has been inserted into a container's component sequence.

Parameters:

container - The container that has changed.

index - The index where the new component has been inserted.

componentsRemoved

default void componentsRemoved(Container container,
                               int index,
                               Sequence<Component> removed)

Called when components have been removed from a container's component sequence.

Parameters:

container - The container that has changed.

index - The starting index of the components that were removed.

removed - The complete sequence of removed components.

componentMoved

default void componentMoved(Container container,
                            int from,
                            int to)

Called when a component has moved from one z-index to another within a container.

Parameters:

container - The container that has changed.

from - The starting index of the component (in Z-order).

to - The place in the Z-order where this component ended up.

focusTraversalPolicyChanged

default void focusTraversalPolicyChanged(Container container,
                                         FocusTraversalPolicy previousFocusTraversalPolicy)

Called when a container's focus traversal policy has changed.

Parameters:

container - The container that has changed.

previousFocusTraversalPolicy - The previous value of the focus traversal policy for this container.
