PointerMove

Struct PointerMove 

Source
pub struct PointerMove {
    pub events: Vec<UiEvent>,
    pub needs_redraw: bool,
}
Expand description

Outcome of a pointer-move dispatch through [RunnerCore::pointer_moved] (or its backend wrappers).

Wayland and most X11 compositors deliver CursorMoved at very high frequency while the cursor sits over the surface — even sub-pixel jitter or per-frame compositor sync ticks count as movement. The vast majority of those moves are visual no-ops (the hovered node didn’t change, no drag is active, no scrollbar is dragging), so hosts must gate request_redraw on needs_redraw to avoid spinning the rebuild + layout + render pipeline on every cursor sample.

Fields§

§events: Vec<UiEvent>

Events to dispatch through App::on_event. Empty when the move didn’t trigger a Drag or selection update.

§needs_redraw: bool

true when the runtime’s visual state changed enough to warrant a redraw — hovered identity changed, scrollbar drag updated a scroll offset, or events is non-empty.
