qt - Render web content offscreen using QtWebEngine -

i trying port application uses qtwebkit render web content on 1 uses qtwebengine.

i limited can change architecturally have stick current approach of rendering page, capturing memory buffer , moving across different process buffer used texture in opengl.

i've tried porting code on (broadly speaking) replacing webkit webengine, apis different.

can tell me if possible? if so, please point me in right direction illustrates how hook up.

yes, apis different, , code path used rendering uses scene graph (yes, widgets-based api).

so in case not webengine-specific problem rather problem of how pixels out of qt quick scene. qquickrendercontrol, introduced in qt 5.4 trying address.

qtwebengine might have additional quirks related visibility when doing offscreen stuff in 5.4, hopefully fixed in 5.5 though.

this use case not demonstrated qtwebengine examples, contributions welcome.
