Native widgets are those of the native widget toolkit. I can use the underlying drawing libraries to draw widgets that look vastly different and implement behaviours that behave vastly differently from the native widget toolkit.
The point of native widgets is that they are the same, not that they are drawn using the same underlying technology.
So the fact that you are using platform libraries to draw those non-native widgets is not at all relevant. After all, what else are you going to be using?
