Detect if a widget is using opengl rendering

Hi Guys,

Following an issue where addToDesktop with temporary window do not work when the main window is attached to an opengl context, I am wondering if there is a way to know a component is attached to a gl context ?



I've added a method to do this now: OpenGLContext::getContextAttachedTo()


Actually I've found my temporary window bug using this.

It seems that OSX do not like having the following situation:

Child A with GL and child B without GL with the same parent without GL.

In that case, Child B is not drawn


Thanks !
