Struct Panel 

pub struct Panel<Msg> { /* private fields */ }

A surface one step above its background, optionally titled, selectable and pressable.

A pressable panel answers the pointer like a button: hovering raises its surface one tone and shows a soft pillar down its whole left edge, pressing flashes one tone brighter, and focus reached with the keyboard raises it with a breathing pillar. A selected panel keeps the accent pillar down the same edge, as on dialogs. Panels without on_press, and disabled ones, never react to the pointer.

Style keys: panel (bg, padding, pillar), panel-title (fg, bold), states hover, focus and pressed (pressable panels only) and selected.

Implementations

impl<Msg: 'static> Panel<Msg>

pub fn new() -> Self

An untitled panel. Add its content with View::add_with.

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

A small heading drawn in the panel’s first row.

pub fn variant(self, variant: impl Into<String>) -> Self

Theme variant.

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

Raises the panel to the selected surface with the accent pillar.

pub fn gap(self, rows: u16) -> Self

Rows between children; 1 by default.

pub fn on_press(self, message: Msg) -> Self

Makes the whole panel pressable, like a card that opens something. Enter or Space presses it while focused; a click presses it on release, and releasing away from the panel cancels.

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

Keeps a pressable panel from being hovered, focused or pressed; its message is not sent. It still shows whether it is selected.

Trait Implementations

impl<Msg: Clone + 'static> Container<Msg> for Panel<Msg>

fn set_children(&mut self, children: Vec<Node<Msg>>)

Receives the children built for this widget.

impl<Msg: 'static> Default for Panel<Msg>

fn default() -> Self

Returns the “default value” for a type.

impl<Msg: Clone + 'static> Widget<Msg> for Panel<Msg>

fn measure(&self, cx: &mut MeasureCx<'_>, available: Size) -> Size

The size the widget wants when it may use up to available.

fn paint(&self, cx: &mut PaintCx<'_>, area: Rect)

Draws the widget into area.

fn event(&self, cx: &mut EventCx<'_, Msg>, event: &Event) -> bool

Handles input. Returns true when the event was used; unused key and scroll events bubble to the parent widget.

fn focusable(&self) -> bool

Whether the widget can take keyboard focus.

fn children(&self) -> &[Node<Msg>]

Child nodes, for widgets that contain other widgets.

fn children_mut(&mut self) -> &mut [Node<Msg>]

Mutable child nodes, used to assign ids.

fn paint_overlay(&self, _cx: &mut PaintCx<'_>, _anchor: Rect)

Draws the widget’s overlay after the whole view was painted, when it asked for one with PaintCx::request_overlay. anchor is the area the widget was painted in.
