It appears that one might not even be able to make use of QRhi without porting all the QWidget-based UI over to Qt Quick.
Given how some high-profile Qt applications are using OpenGL, continuing with using ANGLE would seem to be the superior choice over having to rewrite everything with a completely new API.
- jcelerier 6y agoI use QRhi for the shader pipeline in https://ossia.io https://ossia.io which is a QWidget desktop app
- divingdragon 6y agoJust curious: Is it possible to do rendering with QRhi inside QWidget in a similar way as one would do with QOpenGLWidget? Actually, the post also stated that using `QQuickWidget` will force OpenGL composition, so if an application uses QML inside QWidget it looks like QRhi will not be usable at all. It would seem that QWidget composition does not support QRhi.

- jcelerier 6y agoIt works fine with QWidget::createWindowContainer on the QRhi viewport here : https://jeanmichael-gmail.tinytake.com/tt/NDc3MjgxOF8xNTA4MTIwOQ https://jeanmichael-gmail.tinytake.com/tt/NDc3MjgxOF8xNTA4MT... top is your most classic QTreeView, bottom is the widget with content rendered through RHI (a preview of a shader effect)
- divingdragon 6y agoAh right, createWindowContainer should work for this. I believe there is a reason why we don't call createWindowContainer with our use of QOpenGLWidget, though I currently can't remember it. If it still applies, then I suppose we might not be able to use QRhi.
