Hey2,<br>
<br>
I've been playing with this myself a bit, but have not gotten too
far, summer weather, travels and all. What Ville is suggesting is
exactly what I'm after - not a full binding set, but just a UI
bridge. In API rich environments like python/.net/etc the
"application framework" API parts of Qt don't mean much (and their
existence/quality varies depending on platform anyway). Mono (and
even Xamarin) falls a bit short on the UI side, and a good
QML/QtQuick bridge would help a whole lot. And before someone gets
the wrong idea - this is still not about having a single QML
codebase, but rather having a "common language" for UIs powered by
whatever is the best tech choice on the given platform (QtQuick,
Silica, QML components wrapping native APIs, you name it).<br>
<br>
Best regards<br>

We discussed this on twitter already, but here we go
in >140 characters as well ;-).<br>

Making it possible to create QML applications with Mono
would be interesting on every platform, not merely
Sailfish. Think Android, iOS, desktop. Xamarin costs
nontrivial amount of money, so QML + Mono would be a
free alternative to that (with somewhat limited
capabilities of course).,<br>
<br>
</div>
Better path than QtSharp would be just creating a QML
bridge to Mono, i.e. instantiate a QML runtime and make
Mono talk with it. Example for this architecture is
PyOtherside (<a moz-do-not-send="true"
href="http://thp.io/2011/pyotherside/">http://thp.io/2011/pyotherside/</a>)<br>
<br>
</div>
Sufficient api would be:<br>
<br>
</div>
- register Mono functions to be callable from QML javascript<br>
<br>
</div>
<div>Analogue: <a moz-do-not-send="true"
href="http://pyotherside.readthedocs.org/en/latest/#call">http://pyotherside.readthedocs.org/en/latest/#call</a><br>
</div>
<br>
- receive "signals" (free form objects) from Mono side<br>
<div>
<div>

<div>Another example (though a lot larger) is golang-qml
binding: <a moz-do-not-send="true"

<br>
</div>
<div>Mechanically exposing large parts of Qt's C++ api
(including QML engine) like sip, pyside et al are doing
is probably going to yield lots of unuseful code, where
developers only need 2% subset, but you will pay the
price of the bloat and complexity anyway (troubles with
PySide are a good example of this). Therefore I think
QtSharp is suboptimal approach. <br>

<div>I'm happy to announce that development on Mono for
Sailfish is underway (<a moz-do-not-send="true"
href="http://monoforsailfish.com" target="_blank">http://monoforsailfish.com</a>).
This is a continuation of MonoTizen (<a
moz-do-not-send="true" href="http://monotizen.com"
target="_blank">http://monotizen.com</a>), on which
development has been suspended because the Tizen project
is broken (see <a moz-do-not-send="true"

<div>Dimitar Dobrev, the author of <a
moz-do-not-send="true"
href="https://github.com/ddobrev/QtSharp"
target="_blank">https://github.com/ddobrev/QtSharp</a>
has been upstreaming bug-fixes (and addressing newly
discovered issues in) to <a moz-do-not-send="true"
href="http://github.com/mono/CppSharp"
target="_blank">http://github.com/mono/CppSharp</a>.
He'll be building the bindings, and will probably
end up doing the Mono Runtime port as well, based on
the fantastic job which Damien Diederen did for the
Tizen Mono Runtime.</div>
