Class ComponentEvent

java.lang.Object

java.util.EventObject

java.awt.AWTEvent

vaadinx.awt.event.ComponentEvent

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

ContainerEvent, FocusEvent, InputEvent, PaintEvent, WindowEvent

public class ComponentEvent
extends AWTEvent

Port of ComponentEvent. AWT's version types its source as java.awt.Component and vaadinx.awt.Component isn't castable to that (D_event_port_policy). We extend java.awt.AWTEvent — reused unchanged per D_whitelist_porting since AWTEvent's own source type is Object — and replace only the Component-typed fields and accessors.

Nothing in the current slice actually fires ComponentEvent; the class exists so ContainerEvent has the right parent. The id-range constants are kept at AWT's values so any user code that compares them to AWT constants still works.

Method Details

getComponent

public Component getComponent()

Returns the originating component. Cast to vaadinx.awt.Component is safe because the constructor is the only entry point and requires exactly that type.
