UI

public UI()

Create a new UI object

UI

public UI(org.jdom.Element config)

Creates a new UI object

Parameters:

config - configuration element

Method Detail

setObjectFactory

public void setObjectFactory(UIObjectFactory objFactory)

Assigns an object factory use to create new object instances. If no object factory is asigned, UI uses the default classloader

Parameters:

objFactory - reference to an Object Factory

setConfig

public void setConfig(org.jdom.Element config)

Parameters:

config - the Configuration element

setLog

public void setLog(Log log)

Parameters:

Log - an optional Log instance

Log

getLog

public Log getLog()

getRegistrar

public java.util.Map getRegistrar()

UI uses a map to hold references to its components ("id" attribute)

Returns:

UI component registrar

get

public java.lang.Object get(java.lang.String id)

Parameters:

id - Component id ("id" configuration attribute)

Returns:

the Object or null

public javax.swing.JComponent create(UI ui,
                                     org.jdom.Element e)

UI is itself a UIFactory. This strategy is used to recursively instantiate components inside a container

Specified by:

create in interface UIFactory

Parameters:

ui - reference to this UI instance

config - free form configuration Element

Returns:

JComponent

newInstance

public java.lang.Object newInstance(java.lang.String clazz)
                             throws java.lang.Exception

Specified by:

newInstance in interface UIObjectFactory

Parameters:

clazz - the Clazzzz

Returns:

the Object

configure

public void configure()
               throws org.jdom.JDOMException

configure this UI object

Throws:

org.jdom.JDOMException

reconfigure

public void reconfigure(java.lang.String elementName,
                        java.lang.String panelName)

reconfigure can be used in order to re-configure components inside a container (i.e. changing a panel in response to an event).

Parameters:

elementName - the element name used as new configuration

panelName - panel ID (see "id" attribute)
