 org.wings.event.SComponentEvent
All known Subclasses: org.wings.event.SContainerEvent, org.wings.event.SParentFrameEvent,
| SComponentEvent | | public class SComponentEvent extends java.awt.AWTEvent (Code) | | A low-level event which indicates that a component moved, changed
size, or changed visibility (also, the root class for the other
component-level events).
Component events are provided for notification purposes ONLY;
WingS will automatically handle component moves and resizes
internally so that GUI layout works properly regardless of
whether a program is receiving these events or not.
In addition to serving as the base class for other component-related
events (InputEvent, FocusEvent, WindowEvent, ContainerEvent),
this class defines the events that indicate changes in
a component's size, position, or visibility.
This low-level event is generated by a component object (such as a
SList) when the component is moved, resized, rendered invisible, or made
visible again. The event is passed to every ComponentListener or
ComponentAdapter object which registered to receive such
events using the component's addComponentListener method.
(ComponentAdapter objects implement the
ComponentListener interface.) Each such listener object
gets this ComponentEvent when the event occurs.

| SComponentEvent | | public SComponentEvent(SComponent aSource, int anId)(Code) | | Constructs a ComponentEvent object.
Parameters:
aSource - the Component object that originated the event
Parameters:
anId - an integer indicating the type of event |
| getComponent | | public SComponent getComponent()(Code) | | Returns the originator of the event.
the Component object that originated the event |
| paramString | | public String paramString()(Code) | | Returns a string representing the state of this event. This
method is intended to be used only for debugging purposes, and the
content and format of the returned string may vary between
implementations. The returned string may be empty but may
not be null.
