Struct HitTestItem 

pub struct HitTestItem {
    pub point_in_viewport: LogicalPosition,
    pub point_relative_to_item: ContentBoxLocal,
    pub is_focusable: bool,
    pub is_virtual_view_hit: Option<(DomId, LogicalPosition)>,
    pub hit_depth: u32,
}

A single hit-test result for a regular (non-scroll) DOM node.

Fields

point_in_viewport: LogicalPosition

The hit point in the coordinate space of the “viewport” of the display item. The viewport is the scroll node formed by the root reference frame of the display item’s pipeline.

point_relative_to_item: ContentBoxLocal

The hit point relative to this node’s static CONTENT-box origin, with the node’s own scroll offset NOT applied.

Why this space, and why it is typed

The two hosts used to disagree here. WebRender reports the point relative to the hit RECT, which azul pushes before the scroll frame — i.e. BorderBoxLocal — while the CPU tester used in headless E2E subtracted padding + border and reported ContentBoxLocal. Same click, two answers, differing by exactly the node’s content inset. It stayed latent only because the default TextInput’s value <p> sets neither padding nor border; it goes live for any padded editable.

Both producers now emit ContentBoxLocal, because that is the space the consumer that cares (UnifiedLayout::hittest_cursor, via LayoutWindow::ifc_local_point) actually needs. Consumers wanting the border-box-relative point the public CallbackInfo::get_cursor_relative_to_node promises convert back with ContentBoxLocal::to_border_box_local.

is_focusable: bool

Necessary to easily get the nearest VirtualView node

is_virtual_view_hit: Option<(DomId, LogicalPosition)>

If this hit is a VirtualView node, stores the VirtualViews DomId + the origin of the VirtualView

hit_depth: u32

Z-order depth from WebRender hit test (0 = frontmost/topmost in z-order). Lower values are closer to the user. This preserves the ordering from WebRender’s hit test results which returns items front-to-back.
