Hi, Patrick,
in Java port we do the same: store Frame* in FrameLoaderClient. However,
this frame's loader URL can't be used, for example, in
postProgressStartedNotification as it contains the current URL, not the
URL which is about to be loaded...
Thanks,
Artem

Artem,
For our port, we construct the FrameLoaderClient with a pointer to the
Frame object. So in all the progress notification callbacks we can say
m_frame->loader()->url() or whatever to get the current url of the frame.

Hi,
I work on dispatching web load/progress events for Java port and have
some questions about notifications in FrameLoaderClient class.
1. What is the right method to implement to get a 'page load started'
and 'page load finished' events? I tried the following methods:
postProgressStartedNotification()
postProgressFinishedNotification()
and the problem is they don't accept any params, so I can't get an URL
being loaded. If I obtain the URL from frame->loader->documentLoader,
it works for 'progress finished' notification, but returns an old URL
for 'progress started'.
2. What is the right method to implement to get a 'main document load
started'? I see the method
dispatchDidLoadMainResource()
but there is no similar method about starting...
3. As I understand, the right way to handle resources (for example,
images) loading is to track methods
assignIdentifierToInitialRequest()
dispatchWillSendRequest()
dispatchDidFinishLoading()
The latter two methods provide request identifiers which are assigned
in the former one. However, sometimes I see two
'dispatchWillSendRequest' calls with the same ids and different URLs.
For example, when loading www.google.com I the first URL is
www.google.com and the second is www.google.co.uk. How is this
situation should be handled?
4. There are several notifications about resource loading is finished:
dispatchDidFinishLoading()
dispatchDidFinishLoad()
dispatchDidFinishDocumentLoad()
didFinishLoad() - is this a notification?
finishedLoading() - is this a notification?
Some of them provide DocumentLoader instances, others have no
parameters passed. What is the difference between these methods? Are
some of them outdated and shouldn't be used at all?
Thanks,
Artem
