_LOAD_EVENT_TYPE

private static Object _LOAD_EVENT_TYPE

Constructor Detail

AdfDhtmlInlineFramePeer

public AdfDhtmlInlineFramePeer()

Method Detail

BindToComponent

protected void BindToComponent(AdfUIComponent component,
HTMLElement domElement)

If the sizing is "preferred", registers a resize listener.

Parameters:

component	-	target component to bind
domElement	-	dom element component is bound

Return:

void - null

Overrides:

AdfRichUIPeer.BindToComponent(Object, Object)

ComponentRemoved

protected void ComponentRemoved(AdfUIComponent component)

Override to unregister this iframe from the polling lsit.

Parameters:

component

-

Component being disassociated from the peer

Return:

void - null

Overrides:

AdfUIPeer.componentRemoved(AdfUIComponent)

ComponentSourceChanged

protected void ComponentSourceChanged(AdfRichInlineFrame component,
Object domElement,
String newValue,
Object oldValue)

Optimized setter for the "source" attribute.

Parameters:

component	-	inline frame
domElement
newValue	-	new source property value
oldValue

Return:

void - null

__getIframe

HTMLIFrameElement __getIframe(HTMLElement domElement)

Parameters:

domElement

-

optional element if called before the component has fully initialized Default value = null

Return:

HTMLIFrameElement - returns the iframe that contains the source document. The location of the iframe under the inlineFrame component varies depending on the agent. This method will return the iframe regardless of the agent.

__iframeLoadHandler

static Object __iframeLoadHandler(Object evt)

This is an "onload" callback registered on the iframe by the server-side renderer. This is necessary because InitDomElement will always come after the iframe has finished loading.

Parameters:

evt

Return:

Object

InitDomElement

protected void InitDomElement(AdfUIComponent component,
HTMLElement rootElement)

Initialize the associated domElement when the peer is created. Stateless peers are not bound at the time that this method is called. Lazily sets the "scr" attribute of the iframe to minimize the number of verbose GET request when the iframe element is re-parented.

Parameters:

component	-	Component that this peer will be associated with
rootElement	-	Root DOM element of this peer

Return:

void - null

Overrides:

AdfRichUIPeer.InitDomElement(AdfUIComponent, Object)

InitSubclass

protected static Object InitSubclass()

Override to initialize the array used for tracking iframe's that need their preferred size calculated

Return:

Object

_isIframeSizingAllowed

private static boolean _isIframeSizingAllowed(HTMLElement iframeDom)

Tests if we can can size the iFrame source. If we cannot, a warning is logged and the method returns false. This method should be checked before setting sizing to preferred, to see if user has an invalid setup - source set outside the server's domain and sizing set to preferred.

Parameters:

iframeDom

-

the iframe dom source

Return:

boolean - true if access is allowed

_minSizeResizeListener

private static void _minSizeResizeListener()

Timer callback for performing resizing on the registered iframes.

Return:

void - null

_registerIFrameForSizing

private static void _registerIFrameForSizing(HTMLElement iframeDom)

Called when a new iframe needs to be registered with the resizing service.

Parameters:

iframeDom

Return:

void - null

_removeLoadingStatus

private static Object _removeLoadingStatus(Object iframeDom,
Object clientId)

Parameters:

iframeDom
clientId

Return:

Object

_resizeIframeToPreferred

private static Boolean _resizeIframeToPreferred(HTMLElement iframeDom)

Resizes the iframe to its preferred size, returning true if any resizing actually ocurred.

Parameters:

iframeDom

Return:

Boolean - true if any resizing occurred.

ScrollIntoView

protected void ScrollIntoView(Object component,
Object focus,
String subTargetId)

Overrriden to provide Inline Frame specific implementation.

Parameters:

component
focus
subTargetId	-	optional component dependent DOM sub-id that needs to be scrolled/focused into view Default value = null

Return:

void - null

Overrides:

AdfRichUIPeer.scrollIntoView(Object, Object, String)
