[Qt-qml] Flickable WebBrowser: how to update contentY property when user clicks on a same-page anchor ?

[Sacha Zyto]

Good afternoon

I have a WebView embedded inside a Flickable, and I'm trying to move the 
page appropriately when a user clicks on a link that's an anchor to the 
same page, such as:

<a href="#references">Jump to References</a>

I looked at the source code in demos/declarative/webbrowser, but I fear 
that they may have forgotten about the use of links for that purpose, 
since the code in FlickableWebView looks like:

(...)
       onUrlChanged: {
             // got to topleft
             flickable.contentX = 0
             flickable.contentY = 0
             if (url != null) { header.editUrl = url.toString(); }
         }
(...)

contentY shouldn't typically be set to 0 if the url changes just by the 
anchor part (i.e. from http://www.example.com#section1 to 
http://www.example.com#section2). My question is: Does the QML WebView 
element exposes enough of its state in its API so that we can actually 
scroll to the right place on the page ? If not, shouldn't we submit a 
bug report or feature request ?

Example:
Use the demos/declarative/webbrowser QML example and visit
http://en.wikipedia.org/wiki/Uniform_Resource_Locator
... and try any of the "Contents" link: Instead of scrolling to the 
right place on the page, it will go back to the top of the document.

Best,
Sacha
