Method Detail

init

public void init()

Specified by:

init in class AbstractFrameEventHandler

onFrameReady

public void onFrameReady()

Overrides:

onFrameReady in class AbstractFrameEventHandler

registerLoadHandler

public void registerLoadHandler()

Registers two separated implementations of an onload event. In case the onload is not triggered it's supposed to fallback on a readystate poller. We have to make sure, that they don't interfere by using a loaded boolean.

notifyUrlChange

public void notifyUrlChange()

Specified by:

notifyUrlChange in class AbstractFrameEventHandler

registerUnloadHandler

public void registerUnloadHandler(com.google.gwt.dom.client.Element element,
                                  com.google.gwt.user.client.Timer timer)

This function is supposed to trigger an unload event, when the page inside the Iframe is changed. Doesn't work, that's why browsing inside the iframe is broken for webkit.

initNativeTouchSelectionListener

public void initNativeTouchSelectionListener(com.google.gwt.dom.client.Element element,
                                             PageEditorView.Listener listener)

Custom implementation for iPads of the touch end handling. Suppresses the selection, when scrolling.

Overrides:

initNativeTouchSelectionListener in class AbstractFrameEventHandler

initNativeKeyListener

public void initNativeKeyListener(com.google.gwt.dom.client.Element element)

Description copied from class: AbstractFrameEventHandler

Catches key events on the contentDocument of the frame Element and fires it on the frame to enable event bubbling from the frame up to the DOM.
