A while back, I asked a question on StackOverflow about how to use an item's parent as a ShaderEffectSource:
http://stackoverflow.com/questions/9510013/is-there-some-way-i-can-have-a-qml-widget-affect-the-content-below-it-with-a-gls The code in the response looked at first glance like it should work, but the trouble is that when you use an item as a ShaderEffectSource, you also get all of its children. Setting "recursive" to true doesn't fix this, and in any case the real solution here is *not* to include the current current element (or the ones above it) in the source. It seems to me that, rather than *requiring* that recursive be set to true in these cases, it would be better to get the shader effect source by rendering everything *below* it. Is this something that would be reasonably easy to add? It seems to me like it would be an important feature for anyone wanting to build a UI that has multiple child windows and uses shaders. -- --
