Struct Elapsed 

pub struct Elapsed<M = ()>(/* private fields */);

elapsed: a live timer Tern clocks.

Implementations

impl<M> Elapsed<M>

pub fn key(self, key: impl Into<NodeKey>) -> Self

Identity among siblings: keeps the node’s id (and Tern’s view state) across reorders. A string, or an integer.

The accessible name of a node that shows no text.

Flex basis: a fraction of the parent, or the content’s size.

pub fn min(self, min: Bound) -> Self

Lower size bounds.

pub fn prop(self, name: &str, value: impl Serialize) -> Self

Sets any prop untyped; null removes it.

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

A tooltip.

pub fn max(self, max: Bound) -> Self

Upper size bounds (a max.h also clips the node).

pub fn actions(self, actions: Actions) -> Self

What a pointer does, by action name.

pub fn on_click(self, msg: M) -> Self

where M: Clone + Send + Sync + 'static,

Sends msg on a click (sets actions.click to "click" unless the node names its click action itself).

pub fn on_dblclick(self, msg: M) -> Self

where M: Clone + Send + Sync + 'static,

Sends msg on a double click (sets actions.dblclick to "dblclick" unless the node names it).

pub fn on_menu(self, act: impl Into<String>, msg: M) -> Self

where M: Clone + Send + Sync + 'static,

Adds act to the context menu and sends msg when it is picked.

pub fn on_action(self, act: impl Into<String>, msg: M) -> Self

where M: Clone + Send + Sync + 'static,

pub fn on_toggle(self, f: impl Fn(bool) -> M + Send + Sync + 'static) -> Self

Maps toggle events (the new collapsed) to a message.

pub fn on_select(self, f: impl Fn(&str) -> M + Send + Sync + 'static) -> Self

Maps select events (the item) to a message. On a list’s item the item’s own handler runs first.

pub fn on_activate(self, f: impl Fn(&str) -> M + Send + Sync + 'static) -> Self

Maps activate events (the item) to a message.

pub fn on_change(self, f: impl Fn(&Change) -> M + Send + Sync + 'static) -> Self

Maps change events to a message.

pub fn on_focus(self, msg: M) -> Self

where M: Clone + Send + Sync + 'static,

pub fn on_edit(self, f: impl Fn(&Edit) -> M + Send + Sync + 'static) -> Self

Maps edit events (native editing) to a message.

pub fn on_undo(self, msg: M) -> Self

where M: Clone + Send + Sync + 'static,

Sends msg on undo events.

pub fn on_send(self, f: impl Fn(&str) -> M + Send + Sync + 'static) -> Self

Maps send events (the text to submit) to a message.

impl<M> Elapsed<M>

pub fn age(self, value: impl Into<i64>) -> Self

Milliseconds already elapsed (negative: a countdown).
