ui::PopupChrome¶

Header: winui/ui/Element.hpp.

How the window draws around a popup's content: the shadow behind it, and the corners and elevation that shadow is cast at.

Field	Type	Default
`shadow`	`bool`	`true`	Whether the window casts the theme's popup shadow behind the content. Off for content that draws all of its own chrome, as a bare Popup's child does.
`corner_radius`	`Callback<float(const Theme& theme)>`		The corner radius the shadow is drawn at under a theme, which has to match the radius the content's own surface takes from that theme. Unset is the theme's `overlay_corner_radius`.
`elevation`	`OptionalFloat`		How high the shadow is cast from, in DIPs, on a theme with Fluent shadows. Unset is a flyout's 32.
`shadow_rect`	`Callback<Rect(const Rect& bounds)>`		The rect the shadow is cast behind, given the popup's arranged bounds. Unset is the whole popup; a surface with a tail or a part still sliding in narrows it.
