PointerInput

Struct PointerInput 

Source
pub struct PointerInput<'a> {
    pub pass: PointerEventPass,
    pub computed_data: ComputedData,
    pub cursor_position_rel: Option<PxPosition>,
    pub pointer_changes: &'a mut Vec<PointerChange>,

    /* private fields */
}
Expand description

Input for pointer handlers.

This type carries pointer event payload, local geometry, and event consumption helpers. Side effects that are not pointer-specific should use dedicated APIs such as semantics modifiers, hover cursor modifiers, window action helpers, or the IME session bridge instead of a generic request bag.

Fields§

§pass: PointerEventPass

Current pointer dispatch pass.

§computed_data: ComputedData

The size of the component node, computed during the measure stage.

§cursor_position_rel: Option<PxPosition>

The position of the cursor, if available. Relative to the root position of the component.

§pointer_changes: &'a mut Vec<PointerChange>

Pointer changes from the event loop, if any.

§key_modifiers: ModifiersState

The current state of the keyboard modifiers at the time of the event.
