Enum OverlayAnchor 

pub enum OverlayAnchor {
    Owner,
    Rect(Rect),
}

What a slot places its surface against.

Both variants resolve to a window-space rect in the owner’s paint, where the owner’s absolute origin is finally known; nothing is subscribed to and nothing is cached across frames, so an anchor follows its owner across scroll, relayout and animation for free.

Variants

Owner

The owner’s own bounds — a trigger floating a menu under itself.

Rect(Rect)

A rect in the owner’s local space: a caret, a selection’s bounding box, a press point, one row of a list. Translated by the owner’s paint origin, so a caller states it in the same coordinates its layout and event already speak.
