The call "m_shadowFBO->texture();" will not return the depth texture that you need for shadow mapping, but the (useless) color texture that your QOpenGLFramebufferObject contains. There's currently no accessor for the depth texture, nor a way to create a QOGLFBO without a color texture. For this kind of usages it would be better if you roll out your own FBO class :\
(5.6 (finally!) introduces support for MRT in QOGLFBO, limited to color textures. In general, QOGLFBO is very limited and needs some love in terms of generalising its API to "modern" FBO usages. I've got a sketch of a QOGLFBOv2, but that's too long to write it in this small margin -- we ought start discussing how to properly develop the OpenGL helpers in QtGui in the post GL-ES2 world, possibly in a playground module.) </ot>
