Can one use VisualElement.X and VisualElement.Y to compute a visual element coordinates in its enclosing window?

[MartyIX]

I have created a demo project here: https://github.com/MartyIX/VisualElementXY202311 (.NET 8 RC2)

It contains the method (added in the commit):

private (double x, double y) GetCoordinatesWithinWindow(VisualElement element)
{
    double x = 0;
    double y = 0;
    VisualElement? workingElement = element;
    while (workingElement is VisualElement visualElement)
    {
        x += visualElement.X;
        y += visualElement.Y;
        workingElement = workingElement.Parent as VisualElement;
    }

    return (x, y);
}

And I wonder whether this compution is fundamentally valid or not. I mean whether the computation gives what I claim it to be - ie coordinates of the element relative to the enclosing window.

Does anybody know?

btw: We experimented with this code and for an element we expected the X coordinate to be equal to 600. However, it turned out to be 600.02489894573 or something. Hence the question about the validition of the approach.

@mattleibow @hartez Would you possibly know please?

This looks valid to me. The slight difference in your actual and expected values might be coming from rounding errors and conversions between native screen locations and the virtual locations (due to differing screen densities).
