class Component
[source: scala/swing/Component.scala]
abstract class Component
extends UIElement
Base class for all UI elements that can be displayed in a window. Components are publishers that fire the following event classes: ComponentEvent, FocusEvent, FontChanged, ForegroundChanged, BackgroundChanged.
Notes
[Java Swing] Unlike in Java Swing, not all components are also containers.

Class Summary
protected trait SuperMixin extends javax.swing.JComponent with AnyRef
This trait is used to redirect certain calls from the peer to the wrapper and back. Useful to expose methods that can be customized by overriding.
Object Summary
object keys extends Publisher
object mouse extends AnyRef
Contains publishers for various mouse events. They are separated for efficiency reasons.
Value Details
override lazy val peer : javax.swing.JComponent
The underlying Swing peer.
