Hi,
I've found my fix, maybe it'll help you if you haven't already solved it:
Given two osgWidget::Windows, and wanting to add one as child to the other (in
OSG 2.6.0), here's what I did:
osgWidget::Window * topWindow ... (box, canvas, etc)
topWindow->getBackground()->setColor(0,1,0,0.2);
osgWidget::Window * subWindow ... (box, canvas, etc)
subWindow->getBackground()->setColor(1,0,0,0.2);
osgWidget::Window::EmbeddedWindow * embedded = subWindow->embed();
embedded->setColor(0,0,0,0); //Gets rid of the opaque white fill
topWindow->addWidget(embedded);
Making the embeddedWindow transparent allowed the subWindow to display
properly, as well as its parent. Now I can see the windows' background colors
with proper alpha.
...
Thank you!
Cheers,
Patrick
