// Associate the progress listener for a "browser" to a listener object:

browserObject.addProgressListener( listObj,
Components.interfaces.nsIWebProgress.NOTIFY_STATE_WINDOW );

// Remember to define the object, something like this:

listObj = new Object();

listObj.wpl = Components.interfaces.nsIWebProgressListener;

listObj.QueryInterface = function(aIID) {
if (aIID.equals(listObj.wpl) ||
aIID.equals(Components.interfaces.nsISupportsWeakReference) ||
aIID.equals(Components.interfaces.nsISupports)) return this;
throw Components.results.NS_NOINTERFACE;
}

listObj.onStateChange = function(aProgress, aRequest, aFlag, aStatus) {
if (aFlag & listObj.wpl.STATE_START) {
// This fires when the load event is initiated
} else {
if (aFlag & listObj.wpl.STATE_STOP) {
if ( aFlag & listObj.wpl.STATE_IS_WINDOW ) {
// This fires when ALL load finish
}
if ( aFlag & listObj.wpl.STATE_IS_NETWORK ) {
// Fires when ALL load are REALLY over,
// do something "final" here
// (my two cents)
} else {
// This fires when a load finishes
}
}
}
return 0;
}

// This fires when the location bar changes i.e load event is confirmed
// or when the user switches tabs
listObj.onLocationChange = function(aProgress, aRequest, aURI) {
// do whatever you want to do
return 0;
}

// For definitions of the remaining functions see XulPlanet.com
listObj.onProgressChange = function() { return 0 };
listObj.onStatusChange = function() { return 0 };
listObj.onSecurityChange = function() { return 0 };
listObj.onLinkIconAvailable = function() { return 0 };

/*
I use the progress listener to trap the end of a local HTML
"template" file loading, and run XSLT transormations.
In addition I need to evaluate the browser contentDocument DOM
in order to clean "target" attributes on links, and so on.

Hi Pengyu Hong,
I'm also trying to add a progress listener to the browser object from
my XPCOM code.
How can I get a reference to the main browser (i.e what is
browserObject)?
Thanks,
Ziv

Hello, Marco.

This thread is quite old, but I would like to resume it due to a situation
that I am experiencing.
My question is, on the sequence you described, where will the DOM
unloadevent of the former page be generated? Is it possible that it
will be
generated after the onLocationChange event?

Thanks in advance for your help

Cheers,
Oliveiros
