Hello everyone,<br>
<br>
I'm currently integrating in osgViewer the transparency an I'm
looking for some advices.<br>
I started with the code published by Chris Hidden on the mailing
list, and modified it a little bit in order to be able to choose
between color transparency (LWA_COLORKEY), or alpha transparency
(LWA_ALPHA) or both. The probleme is that it is, for the moment,
done during the window creation. What I wanted is to be able to
adapt the LWA_COLORKEY whenever the user wants, same for LWA_ALPHA.
My questions to the community :<br>
<ol>
<li>Where would be the right place to make these changes (as I
need to be able to recover the window handle) ?</li>
<li>Do you think that it could be interesting to be able to switch
from transparent to non transparent during execution ?</li>
<li>Should the color, alpha and activation boolean be added to the
traits and be modified through GraphicsWindow class ?</li>
<li>Has someone already implemented the transparency for another
OS / Windowing System, and if yes could we try to unify the way
it is done ?</li>
</ol>
<p>Sorry for all these questions, but as it is my first contribution
try, I want to be sure to make no mistake !<br>
</p>
<p>Cheers,<br>
