pub fn Popover<'a>(open: bool) -> PopoverScope<'a>Expand description
A floating box of any content attached to its anchor.
The anchor is always drawn. The content is drawn only while open is true, and open
is the application’s: pressing outside the box or pressing Escape calls on_dismiss
once and changes nothing, so the handler is where the application closes it or keeps
it open to ask about unsaved work.
The Renderer places the box. It opens on the side placement names, lined up with the
edge align names, and it moves to the opposite side or slides along the edge when it
would otherwise leave the window.
modifier belongs to the floating box, not to the anchor: a shape, a border, a shadow
or a material given there replaces the design system’s for this box.
