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

seg: a status bar segment.

Implementations

impl<M> Seg<M>

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

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

A name of yours, exposed to CSS as data-role.

pub fn tone(self, tone: impl Into<Tone>) -> 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,
