Description mikael.lammentausta 2011-07-17 00:06:09 EEST

example presenting the issue with offline caching

HTML5 manifest cache enables web applications to be used without network
connection.

Qt supports this through various settings, and
QWebSettings.enablePersistentStorage() will let a QWebView to utilize this
feature.

However, this did not seem to work propely on PySide using Qt4.6 or Qt4.7. I
tried to debug this for quite a long time until almost by accident found a
"workaround". The attached example comments the problem and the workaround.

I've no idea if this is a problem in Qt or PySide, but I wanted to document
this somewhere so other people who bump into this would know there is a
solution.

Hi Mikel,

I have discussed with the Webkit guys and this is the correct behavior of
webkit.

The function 'setUrl' starts the loading process and without a network this
will fail. Then you need first configure the cache information and after that
set the url. If you do that first, the load load process will fail.
