documentStarted

public void documentStarted()

Description copied from interface: DocumentListener

Indicates document has been requested (e.g. a new document is going to be loaded). This will be called before any activity takes place for the document.

Specified by:

documentStarted in interface DocumentListener

documentLoaded

public void documentLoaded()

Description copied from interface: DocumentListener

Indicates document layout has complete, e.g. document is fully "loaded" for display; this is not a callback for the document source (e.g. XML) being loaded. This method will be called on every layout run (including, for example, after panel resizes).

Specified by:

documentLoaded in interface DocumentListener

setStatus

public void setStatus(String txt)

Sets the status attribute of the BrowserPanel object

Parameters:

txt - The new status value

updateButtons

protected void updateButtons()

onLayoutException

public void onLayoutException(Throwable t)

Description copied from interface: DocumentListener

Called when document layout failed with an exception. All Throwable objects thrown (except for ThreadDeath) during layout and not otherwise handled will be provided to this method. If a DocumentListener has been defined an XHTML panel, the listener is entirely responsible for handling the exception. No other action will be taken.

Specified by:

onLayoutException in interface DocumentListener

onRenderException

public void onRenderException(Throwable t)

Description copied from interface: DocumentListener

Called when document render failed with an exception. All Throwable objects thrown (except for ThreadDeath) during render and not otherwise handled will be provided to this method. If a DocumentListener has been defined an XHTML panel, the listener is entirely responsible for handling the exception. No other action will be taken.

Specified by:

onRenderException in interface DocumentListener
