Hi, I'm using the WebView QML component in the Harmattan version of my IMAP e-mail client called Trojita [1]. The WebView component is used for rendering of actual e-mails, so I need quite an amount of control over how the webkit underneath operates.
In Qt 4.7 (which ships on Harmattan), I had to basically maintain a fork of the QDeclarativeWebView class, see [2] for how it looks like. The changes I needed were: 1) Make the QWebSettings property available to the QML code, and publish the userStyleSheet property through that. This was needed to make the WebView render things in white on black background [3], a theme which is used throughout my application. 2) Make it possible to provide a custom QNetworkAccessManager for each WebView instance. This is very important for various reasons I outlined in [4] -- in short, each e-mail being displayed must not access the network without an explicit user's acknowledgement for privacy reasons. It can also only ever have access to a single IMAP message at a time. In order to support a use case where multiple messages are open at once, one therefore has to use two distinct QNAM instances, one for each WebView, which makes QDeclarativeNetworkAccessManagerFactory not suitable for this job (apart from any possible threading issues). My patch makes it possible to use a QNAM subclass provided by the user's C++ code. The patches will have to be cleaned up (they're against a 4.7 release of Qt, for one thing, and use Trojita-specific naming to prevent any clashes as well). I am not familiar with Qt5/WebKit release plans and I also don't like wasting time preparing patches which nobody would accept, which is why I'd like to ask here -- would you guys accept patches adding this functionality? And what's the probability of them being included in Qt 5.0?
