public void add(Component pc)
pc
- component to add to this containerpublic void add(Component c, int constraints)
constraints
- layout constraints (a
bitwise OR of static ints in the particular layout)public boolean contains(Object o)
true
if this list contains the specified element.
More formally, returns true
if and only if this list
contains at least
one element e such that (o==null ? e==null : o.equals(e)).
This method returns true
only if the object has been
directly added to this container. If this container contains another
container that contains this object, this method returns
false
.
o
- element whose presence in this container is to be tested
true
if this container contains the specified
object directly; false
otherwise.public Component get(int index)
index
- the index of the item to be retrieved from this
container
public int indexOf(Component pc)
pc
- component to search for
public boolean isEmpty()
true
if the container contains no components.
true
if this container contains no components;
false
otherwise.public int size()
