Hello all!
I was reading this interesting thread, still fresh:
http://lists.qt-project.org/pipermail/development/2013-August/012492.html
And I have to say is that I'm very interested in how developers can use
resources that already exists in the Qt framework, specially about
networking.
An example: some time ago, I needed to start refactoring an application
(that uses Qt + WebKit) to load content from an arbitrary source - a
local database, as example. So, to have an webkit desktop based
application that talks to the web and still communicate to the web, I
got to get rid of setHtml("...") and stuff; and I did it by "creating my
own scheme" on QNetworkAccessManager. It is hosted on github:
https://github.com/vltr/webkit-scheme-qt5.1
By doing this, I can develop the application's content using
Chrome/Safari and then just wrap it into a database. Voilà!
Ok, that was the easy part. Now the "thing" that is preventing me from
sleep: since I'm making it all (the javascript / html / css) in a
"transparent way", I would like also to send signals to my (client)
application. I know I can call a JavaScript function from inside WebKit,
but instead of that I wanted to "mock" the response of a websocket.
Since my client will always be the same, I can't worry much about "will
it work" and have the same transparent layer of code to write outside
the Qt + Webkit structure.
The question is: how would I mock a simple websocket? One thing I (may)
know: it should be by using the QIODevice, lol. If my line of thought is
right, I can write a QIODevice that provides frames for the websocket,
reading my application's custom signals and sending them to the
"client". It should also never send the close signal (am I right?). The
problem is: can it be made in a simple way? And, if this "simple way"
exists, would it block my client and then should be run on a separate
thread?
As I know there are tons of the most diverse implementations out there,
maybe someone could give me a hint.
My best regards,
Richard.
