This method is used to compare the receiver object (this
)
with the argument object (arg0
) for equivalence
This method is used to compare the receiver object (this
)
with the argument object (arg0
) for equivalence.
The default implementations of this method is an equivalence relation:
x
of type Any
,
x.equals(x)
should return true
.x
and y
of type
Any
, x.equals(y)
should return true
if and only
if y.equals(x)
returns true
.x
, y
, and z
of type AnyRef
if x.equals(y)
returns true
and
y.equals(z)
returns
true
, then x.equals(z)
should return true
.
If you override this method, you should verify that
your implementation remains an equivalence relation.
Additionally, when overriding this method it is often necessary to
override hashCode
to ensure that objects that are
"equal" (o1.equals(o2)
returns true
)
hash to the same Int
(o1.hashCode.equals(o2.hashCode)
).
Returns a hash code value for the object
Returns 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.

Makes this combo box editable
Makes this combo box editable. In order to do so, this combo needs an editor which is supplied by the implicit argument. For default editors, see ComboBox companion object.

Sets the renderer for this combo box's items
Sets the renderer for this combo box's items. Index -1 is passed to the renderer for the selected item (not in the pull-down menu).
The underlying combo box renders all items in a ListView
(both, in the pull-down menu as well as in the box itself), hence the
ListView.Renderer
.
Note that the UI peer of a combo box usually changes the colors of the component to its own defaults _after_ the renderer has been configured. That's Swing's principle of most suprise.

Used by certain layout managers, e.g., BoxLayout or OverlayLayout to align components relative to each other.
Let's the user make a selection from a list of predefined items. Visually, this is implemented as a button-like component with a pull-down menu.
