One OpenGLContext with multiple OpenGLRenderers?

[timart]

@TonyAtHarrison, I came across another thread where you described your OpenGL setup as:

@TonyAtHarrison

multi-render-view setup

In this instance were you using multiple OpenGLRenderer's as individual Components which were associated with a single managing OpenGLContext and OpenGLRenderer as described above? Could you offer any help to this general question?

It also seems part of my issue is that I need to “leave holes” in JUCE graphical Components as you describe here:

Calling the paint() function BEFORE openGL render in a component?

Are you able to see any of the shader stuff at all if you remove some components or “leave holes” in them? When I say “leave holes”: if you mark an OpenGLContext attached component as opaque but don’t draw into it fully, you will see the contents of the OpenGLRenderer in the “holes”. We use this in our plugins to create multiple “render views”, but it may be useful for debugging your app. If it’s not even shown through those then something else may be wrong. If it is shown underneath componen…
