NavigationMenu

查看源码
pub fn new( root_id: impl Into<ElementId>, state: &NavigationMenuState, items: &'a [NavigationMenuItem], ) -> Self

placementpub const fn placement(mut self, placement: AnchorPlacement) -> Self—

Configures placement for this part.

loop_focuspub const fn loop_focus(mut self, loop_focus: bool) -> Self—

Wrap from the last trigger to the first. The default is `true`.

root_idpub const fn root_id(self) -> ElementId—

Configures root id for this part.

pub const fn root_id(self) -> ElementId
查看源码
itemspub const fn items(self) -> &'a [NavigationMenuItem]—

Configures items for this part.

pub const fn items(self) -> &'a [NavigationMenuItem]
查看源码
axispub const fn axis(self) -> NavigationMenuOrientation—

Configures axis for this part.

pub const fn axis(self) -> NavigationMenuOrientation

valuepub const fn value(self) -> Option<ElementId>—

Configures value for this part.

pub const fn value(self) -> Option<ElementId>
查看源码
roving_valuepub fn roving_value(self) -> Option<ElementId>—

The trigger that owns the bar's single Tab stop. This is the controlled focused value while it names an enabled mounted item, and otherwise the first enabled item, matching the composite-widget convention.

pub fn roving_value(self) -> Option<ElementId>
查看源码
entrypub fn entry(self, value: impl Into<ElementId>) -> Option<NavigationMenuEntry<'a>>—

Describe one declared item.

pub fn entry(self, value: impl Into<ElementId>) -> Option<NavigationMenuEntry<'a>>
查看源码
schedulepub fn schedule<V: 'static>(cx: &mut ViewContext<'_, V>, state: &NavigationMenuState)—

Ask for the one repaint an armed open or close deadline needs. Call this while rendering. A settled navigation menu requests nothing, so the window sleeps.

pub fn schedule<V: 'static>(cx: &mut ViewContext<'_, V>, state: &NavigationMenuState)

NavigationMenu::root_with

查看源码
pub fn root_with(self, root: Element) -> Element

Decorate an application-owned root without adding layout or appearance.

NavigationMenu::root

查看源码
pub fn root(self) -> Element

Create the unstyled root part. Use [`Self::root_with`] to supply an existing element.

NavigationMenu::list_with

查看源码
pub fn list_with(self, list: Element) -> Element

Decorate the application-owned list of items.

NavigationMenu::list

查看源码
pub fn list(self) -> Element

Create the unstyled list part. Use [`Self::list_with`] to supply an existing element.

查看源码
pub fn link_with(self, id: impl Into<ElementId>, active: bool, link: Element) -> Element

Decorate an application-owned navigation link without adding appearance. `active` marks the link for the current destination; it projects as the native selected state rather than as a visual class.

查看源码
pub fn link(self, id: impl Into<ElementId>, active: bool) -> Element

Create the unstyled link part. Use [`Self::link_with`] to supply an existing element.
