Field Detail

support

protected Index support

Support instance for delegation of some Index methods.

Constructor Detail

Index.ArrayChildren

public Index.ArrayChildren()

Constructor for the support.

Method Detail

initCollection

protected Collection initCollection()

If default constructor is used, then this method is called to lazily create the collection. Even it claims that it returns Collection only subclasses of List are valid values.

This implementation returns ArrayList.

Overrides:

initCollection in class Children.Array

Returns:

any List collection.

reorder

public void reorder()

Invokes a dialog for reordering children using IndexedCustomizer.

Specified by:

reorder in interface Index

---

move

public void move(int x,
                 int y)

Description copied from interface: Index

---

exchange

public void exchange(int x,
                     int y)

Description copied from interface: Index
