Sorry, QByteArray is no pdf renderer.
Maybe this w

Have you tried implementing a layout that has a locking mechanism?
In theory you can get the root layout to not layout until you approve the
change? This will produce an unfilled area until you unlock it.

That's a good suggestion, but there are a lot of nice features that the Qt

Menu{id:3 }
Button {id:1 onClicked: menu1.popup()}
Button {id:2 onClick
