Transparency of QGLWidget on other QGLWidgets

[brugere]

hi,

as you read in the title, i have some issues to draw alpha transparent QGLWidget's on other QGLWidgets. I'm using shaders (QGLShaderProgram) to represent a huge amount of data at the same time. Every widget is a way of viewing these data.
But i need some of them to be a bit transparent.

I've tried many solutions (even if it was for simple widgets on QGLWidgets) and none worked. I tried to enable Widget transparency attribute, GL_BLEND is obviously enabled... really i dont know where i have to search : /

If anyone had some information or links about this problem or its solution (if there is any :x)

Thanks !

Is it possible to put your QGL on the different window, make it transparently and put directly on/before the current form?

that can be a solution. Even if having almost 20 windows at the same time does not look logical according to me ...
I will try to deal with it, while there is no other solutions.

Many thanks for reply RainBoy
