Struct Panel 

pub struct Panel { /* private fields */ }

A titled surface with header/footer chrome. Reads like Card but framed: a header (chevron + icon + title/description on the left, actions on the right), the body, and an optional footer. The header gets a bottom divider whenever the body is visible.

Collapsing is controlled, like Modal: the parent owns the flag, passes it through collapsed, and flips it in on_toggle (wired to the header chevron).

Implementations

impl Panel

pub fn new() -> Self

pub fn id(self, id: impl Into<ElementId>) -> Self

Scope the panel’s internal element ids (the collapse chevron). Set one when several collapsible panels are siblings.

pub fn title(self, title: impl Into<SharedString>) -> Self

The header title.

pub fn description(self, description: impl Into<SharedString>) -> Self

Dimmed secondary line under the title.

pub fn icon(self, icon: impl IntoElement) -> Self

Leading header content (e.g. a ThemeIcon), shown before the title.

pub fn action(self, action: impl IntoElement) -> Self

Append one trailing header action (e.g. an ActionIcon).

pub fn actions(self, actions: Vec<AnyElement>) -> Self

Replace the trailing header actions.

pub fn footer(self, footer: impl IntoElement) -> Self

Footer content, rendered under the body behind a top divider.

pub fn padding(self, padding: Size) -> Self

pub fn radius(self, radius: Size) -> Self

pub fn with_border(self, with_border: bool) -> Self

pub fn shadow(self, shadow: Size) -> Self

pub fn collapsible(self) -> Self

Show a collapse chevron in the header. Pair with collapsed + on_toggle.

pub fn collapsed(self, collapsed: bool) -> Self

Whether the body (and footer) are hidden. Controlled by the parent.

pub fn on_toggle( self, handler: impl Fn(&ClickEvent, &mut Window, &mut App) + 'static, ) -> Self

Called when the collapse chevron is clicked. Wire it with cx.listener(...) to flip the parent’s collapsed flag.

Trait Implementations

impl Default for Panel

fn default() -> Self

Returns the “default value” for a type.

impl IntoElement for Panel

type Element = Component<Panel>

The specific type of element into which the implementing type is converted. Useful for converting other types into elements automatically, like Strings

fn into_element(self) -> Self::Element

Convert self into a type that implements Element.

fn into_any_element(self) -> AnyElement

Convert self into a dynamically-typed AnyElement.

impl ParentElement for Panel

fn extend(&mut self, elements: impl IntoIterator<Item = AnyElement>)

Extend this element’s children with the given child elements.

fn child(self, child: impl IntoElement) -> Self

where Self: Sized,

Add a single child element to this element.

fn children(self, children: impl IntoIterator<Item = impl IntoElement>) -> Self

where Self: Sized,

Add multiple child elements to this element.

impl RenderOnce for Panel

fn render(self, _window: &mut Window, cx: &mut App) -> impl IntoElement

Render this component into an element tree. Note that this method takes ownership of self, as compared to Render::render() method which takes a mutable reference.
