<![CDATA[[SOLVED] Apply general shader on whole QGLPainter]]>Hello,

I want to turn on/off a global shader on my application to turn on/off all colors into only two e.g Black/whte using GLSL shaders.

Is there a way to apply a 'global shader' to QGLPainter or need I to add QGLShaderProgramEffect on a root scenenode ?

I managed to call the painter->setUserEffect(shaderEffect) prior draw but I would like to apply it to the whole scene.

Regards
