The description is a bit obscure. Can you show the code you are using ?
What version of Qt are you using ?
On what platform ?
with the QT4.8 on centos7.2. I want to show OSG in QGraphicsview, bind the glviewport and graphicsview to show 2D and 3D graphics. overwrite the graphicsview's drawbackgroud func, the can show 2D and 3D ,but it seems the 3D graphics as the background .the mouse event can only use in 2D QGraphicsview.![alt text](![0_1551144007381_51a5c1a1-3ad8-453c-9f8b-2450ef48c38c-image.png](Uploading 0%) image url) like this.the black was 2D
It seems like they are two view
