Type Alias PopoverCustom 

pub type PopoverCustom = PopoverWidget<OverlayTrigger>;

A popover whose trigger is an arbitrary widget, wrapped in OverlayTrigger.

The third stock shape beside PopoverButton and PopoverIconButton, and what replaced the standalone Popover widget: that type existed only because this generic could not take a non-button trigger.

Aliased Type
