Struct EventCallbackConfig 

pub struct EventCallbackConfig {
    pub phases: Phases,
}

Configuration for event callbacks that determines when they should be invoked during event propagation.

Event listeners in Floem are called during different phases of the event propagation pipeline, similar to the DOM event model. This config allows you to specify which phases your callback should respond to.

Examples

Listen during the target and bubble phases (default):

view
    .on_event_with_config(
        EventListener::Click,
        EventCallbackConfig::default(),
        |cx, _| EventPropagation::Continue,
    )

Listen only during the capture phase (useful for intercepting before child handlers):

view
    .on_event_with_config(
        EventListener::KeyDown,
        EventCallbackConfig {
            phases: Phases::CAPTURE,
        },
        |cx, event| {
            // Handle key down during capture phase
            EventPropagation::Continue
        },
    )

Listen during all phases:

view
    .on_event_with_config(
        EventListener::Focus,
        EventCallbackConfig {
            phases: Phases::CAPTURE | Phases::TARGET | Phases::BUBBLE,
        },
        |cx, _| EventPropagation::Continue,
    )

Fields

phases: Phases

Determines which event propagation phases should trigger this callback.

Trait Implementations

impl Clone for EventCallbackConfig

fn clone(&self) -> EventCallbackConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for EventCallbackConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for EventCallbackConfig

fn eq(&self, other: &EventCallbackConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
