Expand description

P Custom layered foreground generated using a WidgetFn<()>.

If the adorner_fn is not nil, the generated node is layered anchored to the widget inner bounds, displaying like a foreground that is not clipped by the widget and overlays all other widgets and layers not placed above LayerIndex::ADORNER.

The full context is captured for adorner widget so you can use context variables inside without issue.
