Abstract methods

Adds a component with the given constraints to the underlying layout
manager and the component peer. This method needs to interact properly
with method constraintsFor
, i.e., it might need to remove previously
held components in order to maintain layout consistency. See BorderPanel
for an example.

Compares the receiver object (this
) with the argument object (that
) for equivalence.
Compares the receiver object (this
) with the argument object (that
) for equivalence.
Any implementation of this method should be an equivalence relation:
- It is reflexive: for any instance
x
of typeAny
,x.equals(x)
should returntrue
. - It is symmetric: for any instances
x
andy
of typeAny
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any instances
x
,y
, andz
of typeAny
ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
.
If you override this method, you should verify that your implementation remains an equivalence relation.
Additionally, when overriding this method it is usually necessary to override hashCode
to ensure that
objects which are "equal" (o1.equals(o2)
returns true
) hash to the same scala.Int.
(o1.hashCode.equals(o2.hashCode)
).
- Value parameters:
- that
the object to compare against this object for equality.
- Returns:
true
if the receiver object is equivalent to the argument;false
otherwise.- Definition Classes

Calculate a hash code value for the object.
Calculate a hash code value for the object.
The default hashing algorithm is platform dependent.
Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)
) yet
not be equal (o1.equals(o2)
returns false
). A degenerate implementation could always return 0
.
However, it is required that if two objects are equal (o1.equals(o2)
returns true
) that they have
identical hash codes (o1.hashCode.equals(o2.hashCode)
). Therefore, when overriding this method, be sure
to verify that the behavior is consistent with the equals
method.
- Returns:
the hash code value for this object.

A map of components to the associated layout constraints. Any element in this map is automatically added to the contents of this panel. Therefore, specifying the layout of a component via
layout(myComponent) = myConstraints
also ensures that myComponent is properly added to this container.
