public class AdfDhtmlInputListOfValuesPeer
extends AdfDhtmlInputListOfValuesBasePeer

_ICON_ID

private static Object _ICON_ID

_SHOWN

private static Object _SHOWN

Overrides:

AdfDhtmlInputListOfValuesPeer

public AdfDhtmlInputListOfValuesPeer()

Peer for the inputListOfValues component.

FocusNextElement

protected Object FocusNextElement(Object node)

Sets the focus on the next component element which is a tabstop

Parameters:

node

Return:

Object

Overrides:

AdfDhtmlInputListOfValuesBasePeer.FocusNextElement(Object)

HandleComponentClick

protected Object HandleComponentClick(Object componentEvent)

Parameters:

componentEvent

Return:

Object

Overrides:

AdfDhtmlEditableValuePeer.HandleComponentClick(Object)

HandleComponentKeyUp

protected Object HandleComponentKeyUp(Object componentEvent)

Intercept the ctrl+alt+w key combination and activate an associated notewindow if one is open. Note windows do not steal focus when shown. From the notewindow, the same sequence of keys will force navigation back to the owning input component.

Parameters:

componentEvent

-

Key Up event Implements keyboard handling for the peer, e.g. spacebar opens up the dialog Enter key on input field fires validation and on icon opens up the dialog

Return:

Object

Overrides:

AdfDhtmlEditableValuePeer.HandleComponentKeyUp(Object)

InitSubclass

protected static Object InitSubclass()

Registers component onclick event handler

Return:

Object

Overrides:

AdfDhtmlValuePeer.InitSubclass()

LazyInitialize

protected Object LazyInitialize(Object component,
                                Object domElement)

We need to initialize the 'value' property before the user makes any changes so that we're not going to the peer for the 'value' property in the component.setProperty method. See explanation below. Background: 1. In component.setProperty if the old and new value of a property are equal the setProperty method returns without setting anything. This is to avoid unnecessary propertyChangeEvents. 2. We do not send down the 'value' property from the server, so the 'value' property starts out undefined. If a property is undefined then calls to get the current value will go to the peer. So initally calls to getValue() go to the peer's GetComponentValue() Issue: - Mostly component.setProperty will only be called after the user makes a change, and if the property is currently undefined the peer's property getter will be called for the 'old' value. The peer will then return the current value, which is the new changed value. - That means the 'old' value is the same as the new value, and so the property is not set (see point 1 above). - Therefore we need to initialize the 'value' property before the user makes any changes so that we're not going to the peer for the 'value' property in the component.setProperty method.

Parameters:

component

AdfDhtmlEditableValuePeer.LazyInitialize(Object, Object)
