Field Detail

bindingListener

protected SVG12BridgeContext.XBLBindingListener bindingListener

The BindingListener for XBL binding events.

contentListener

protected SVG12BridgeContext.XBLContentListener contentListener

The ContentSelectionChangedListener for xbl:content element events.

mouseCaptureTarget

protected EventTarget mouseCaptureTarget

The EventTarget that has the mouse capture.

mouseCaptureSendAll

protected boolean mouseCaptureSendAll

Whether the mouse capture event target will receive events that do not intersect with its geometry.

mouseCaptureAutoRelease

protected boolean mouseCaptureAutoRelease

Whether the mouse capture will be released on mouse up.

Constructor Detail

SVG12BridgeContext

public SVG12BridgeContext(UserAgent userAgent)

Constructs a new bridge context.

Parameters:

userAgent - the user agent

SVG12BridgeContext

public SVG12BridgeContext(UserAgent userAgent,
                  DocumentLoader loader)

Constructs a new bridge context.

Parameters:

userAgent - the user agent

loader - document loader

SVG12BridgeContext

public SVG12BridgeContext(UserAgent userAgent,
                  InterpreterPool interpreterPool,
                  DocumentLoader documentLoader)

Constructs a new bridge context.

Parameters:

userAgent - the user agent

interpreterPool - the interpreter pool

documentLoader - document loader

Method Detail

createURIResolver

public URIResolver createURIResolver(org.w3c.dom.svg.SVGDocument doc,
                            DocumentLoader dl)

Returns a new URIResolver object.

Overrides:

createURIResolver in class BridgeContext

addGVTListener

public void addGVTListener(Document doc)

Adds the GVT listener for AWT event support.

Overrides:

addGVTListener in class BridgeContext

dispose

public void dispose()

Disposes this BridgeContext.

Overrides:

dispose in class BridgeContext

addBindingListener

public void addBindingListener()

Adds a BindingListener to the XBLManager for the document, so that XBL binding events can be passed on to the BridgeUpdateHandlers.

removeBindingListener

public void removeBindingListener()

Removes the BindingListener from the XBLManager.

addDOMListeners

public void addDOMListeners()

Adds EventListeners to the DOM and CSSEngineListener to the CSSEngine to handle any modifications on the DOM tree or style properties and update the GVT tree in response. This overriden method adds implementation event listeners, so that mutations in shadow trees can be caught.

Overrides:

addDOMListeners in class BridgeContext

addUIEventListeners

public void addUIEventListeners(Document doc)

Adds EventListeners to the input document to handle the cursor property. This is not done in the addDOMListeners method because addDOMListeners is only used for dynamic content whereas cursor support is provided for all content. Also note that it is very important that the listeners be registered for the capture phase as the 'default' behavior for cursors is handled by the BridgeContext during the capture phase and the 'custom' behavior (handling of 'auto' on anchors, for example), is handled during the bubbling phase.

Overrides:

addUIEventListeners in class BridgeContext

removeUIEventListeners

public void removeUIEventListeners(Document doc)

Overrides:

removeUIEventListeners in class BridgeContext

removeDOMListeners

protected void removeDOMListeners()

Removes event listeners from the DOM and CSS engine.

Overrides:

removeDOMListeners in class BridgeContext

storeImplementationEventListenerNS

protected void storeImplementationEventListenerNS(EventTarget t,
                                      String ns,
                                      String s,
                                      EventListener l,
                                      boolean b)

Adds to the eventListenerSet the specified implementation event listener registration.

createSubBridgeContext

public BridgeContext createSubBridgeContext(SVGOMDocument newDoc)

Description copied from class: BridgeContext

This function creates a new 'sub' BridgeContext to associated with 'newDoc' if one currently doesn't exist, otherwise it returns the BridgeContext currently associated with the document.

Overrides:

createSubBridgeContext in class BridgeContext

Parameters:

newDoc - The document to get/create a BridgeContext for.

startMouseCapture

public void startMouseCapture(EventTarget target,
                     boolean sendAll,
                     boolean autoRelease)

Starts mouse capture.

stopMouseCapture

public void stopMouseCapture()

Stops mouse capture.
