Struct Action 

pub struct Action {
    pub intent: &'static str,
    pub handler: ActionHandler,
    pub enabled_when: Option<Prop<bool>>,
}

A widget-owned handler bound to a named intent.

Fields

intent: &'static str

The intent name this action responds to. Matches against Intent::name during dispatch.

handler: ActionHandler

Invoked when a matching intent is dispatched to this widget.

enabled_when: Option<Prop<bool>>

Reactive “is this action currently applicable?” predicate. None means always enabled.

Disabled semantics at dispatch time: the intent propagates past this action as if no match existed here, unless the firing Shortcut has propagate_when_disabled == false, in which case the intent is consumed (dormant) at this level.

Implementations

impl Action

pub fn new(intent: &'static str) -> ActionBuilder

Start building an Action bound to the given intent name.

pub fn is_enabled(&self) -> bool

Resolve the current enabled state. true when no predicate is set; otherwise reads the signal.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result
