[Interest] Render QQuickView into another window?

[MaxEd]

This seems interesting. So, if QQuickRenderControl is public, the code 
to render QQuickWindow to other window would looks like that?

QQuickView view;
view.setSource( "form.qml" );

QWindow *pOtherWindow = QWindow::fromWinId( otherWindowId );
QOpenGLContext ctx;
ctx.makeCurrent( pOtherWindow );

QQuickRenderControl renderControl;
renderControl.initialize( &ctx );

renderControl.setWindow( &view );
renderControl.render();

I'm worried I'm trying to do the wrong thing, though. What I'm after is 
to use Qt Quick for UI alongside Allegro graphic library, i.e. render Qt 
Quick controls over 2d game scene rendered by Allegro. I had some 
success by rendering Allegro scene inside Qt's window in 
beforeRendering, as shown in "OpenGL under QML" example and QmlOgre, but 
I do not like this solution, because Allegro always creates its own 
window, and so I get two windows instead of one. Also, I would like to 
handle user input via Allegro, and it, of course, only receives events 
when they are coming through its own window. So, I would like to render 
Qt into Allegro window instead of the other way around.
