\class Qt3DRender::QNoPicking
\inmodule Qt3DRender
\since 5.14
\brief When a Qt3DRender::QNoPicking node is present in a FrameGraph
branch, this prevents the render aspect from performing picking selection
for the given branch.
When disabled, a Qt3DRender::QNoPicking node won't prevent picking from
being performed. Toggling the enabled property is therefore a way to make a
Qt3DRender::QNoPicking active or inactive.
When using multiple subviewports in the FrameGraph, QNoPicking can be
useful to prevent picking conflicts between overlapping viewports or non
visual ones. It can also be used as an optimization to prevent unnecessary
work for hidden viewports or for sections of the scenes which don't require
any picking.
\code
Qt3DRender::QViewport *viewport = new Qt3DRender::QViewport();
Qt3DRender::QCameraSelector *cameraSelector = new Qt3DRender::QCameraSelector(viewport);
Qt3DRender::QNoPicking *noPicking = new Qt3DRender::QNoPicking(cameraSelector);
Qt3DRender::QClearBuffers *clearBuffers = new Qt3DRender::QClearBuffers(noPicking);
clearBuffers->setBuffers(Qt3DRender::QClearBuffers::ColorDepthBuffer);
Qt3DRender::QRenderPassFilter *mainPass = new Qt3DRender::QRenderPassFilter(cameraSelector);
