QGLWidget on QDeclarativeView. Problems with alpha channel.

[Tuninet]

Hi!,

I'm having troubles mixing content of a QDeclarativeView on a QGLWidget. Basically, I have a floating menu designed using QML as source of a QDeclarativeView with a specific QGLWidget as viewport. On the other hand, I have an architecture of classes that produces a QGLWidget with a rendered image. I'm trying to obtain a unique QGLWidget mixing both of them. Currently, the result is a unique QGLWidget with the image rendered as background but with a black rectangle instead the transparent color of my menu. What I'm doing wrong?

I'm using Qt 4.8.2 on Windows 7.

Thank you in advance.
