Hi guys. I have to render some qml but do not show it and get it render data(buffer) and place it in another place. It is desirable that this could be done in another thread.

I have already found "needed" method grabWindows, but it performace is too low. Is this posible to do it using some private headers?

Will it help if I compile qml?

  • There’s http://doc.qt.io/qt-5/qquickitem.html#grabToImage to grab items. I doubt it’s much faster though, they both use the same functions to dump the FBO contents into an image (which boils down to some sort of glReadPixels). I doubt there’s any threading possible due to how OpenGL works here. – Frank Osterfeld Jul 31 '15 at 08:42
