Struct EventData 

pub struct EventData {

    pub event_type: String,
    pub target: u64,
    pub current_target: u64,
    pub local: (f64, f64),
    pub client: (f64, f64),
    pub key: String,
    pub shift: bool,
    pub ctrl: bool,
    pub alt: bool,
    pub super_: bool,
    pub button: i64,
    pub delta: (f64, f64),
    pub value: String,
    pub default_prevented: bool,
    pub propagation_stopped: bool,
    pub immediate_stopped: bool,
}

The full event payload delivered to a handler. Positional / key / button / delta / value fields carry meaning only for the event types that produce them (a keydown has key + modifiers, a wheel has delta, an input / change has value, and so on); unused fields stay at their defaults.

Fields

event_type: String

Event type name ("click", "keydown", "wheel", …).

target: u64

The node the event originally targeted (packed handle).

current_target: u64

The node whose handler is currently running (packed handle). The driver updates this as it walks the propagation path.

local: (f64, f64)

Pointer position relative to the target’s top-left, logical pixels.

client: (f64, f64)

Pointer position in window (client) coordinates, logical pixels.

key: String

Logical key for keyboard events ("a", "Enter", "ArrowLeft").

shift: bool

Shift held.

ctrl: bool

Control held.

alt: bool

Alt / Option held.

super_: bool

Super / Cmd / Windows held.

button: i64

Pointer button: 0 primary, 1 middle, 2 secondary, -1 none.

delta: (f64, f64)

Wheel scroll delta, logical pixels.

value: String

Text value for input / change events.

default_prevented: bool

Set by prevent_default: the event’s default action is cancelled.

propagation_stopped: bool

Set by stop_propagation: no further nodes receive the event.

immediate_stopped: bool

Set by stop_immediate_propagation: no further handlers run at all.

Trait Implementations

impl Clone for EventData

fn clone(&self) -> EventData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventData

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

Formats the value using the given formatter.

impl Default for EventData

fn default() -> EventData

Returns the “default value” for a type.
