<div class="moz-cite-prefix">Dimitar and others,<br>
<br>
I evaluated using Qyoto for a project I'm working on and - with
regret for all the hard work Dimitar had obviously put in -
decided against it, both because it was buggy and because it was
very slow. When I investigated the speed issue SMOKE relies on
textual matching of function signatures to call functions.
Admittedly the hashes, once matched, are hashed and cached, but
still... It also involved at least 2 transitions from managed to
unmanaged code, which IIRC are expensive in themselves. <br>
<br>
People I know have used SWIG to good effect but I have no personal
experience.<br>
<br>
A statically linked shim file (not a DLL, if possible) - i.e. a
set of functions coded in managed code that each make an unmanaged
call to the "real" function would be the way I would expect.
Coding this by hand would be painful, so a program to generate
them is the obvious response. I believe this is the SWIG way.<br>
<br>
If it were possible I would look into using something like an XML
file containing the interface definition, maybe itself initially
generated from the .h files, and which can then be adapted and
enhanced to improve it. If the Qt and/or SWIG community were
receptive this might become something people would support
generally - e.g. including PyQt et al. - which would benefit
everyone.<br>

Isn't it pity that there is no more interest in
having Qt bindings for<br>
the .NET/Mono? :-(<br>

There was an announcement some years back on one of the
Mono blogs about an interop layer for C++ (<a
moz-do-not-send="true" rel="nofollow" target="_blank"
href="https://github.com/mono/cxxi">https://github.com/mono/cxxi</a>).
It was never mentioned again and I think a grue ate it,
but it looked like a really nice set of libraries if
someone maintained it beyond the initial proof of
concept. I also don't know how tightly it is tied to
Mono itself and if a cross-platform version could be
done with it.<br>
<br>
Looking at the code, they were also using Qt as the
example in their POC.<br>
