Cranpose Foundation

cranpose-foundation defines shared modifier-node, input, focus, text and semantics contracts for Cranpose UI. Framework extension authors use the crate to add modifier nodes and input handlers. App developers usually start with the widgets and Modifier type from cranpose.

Handle a pointer event

PointerEvent carries event kind and logical pointer positions. The platform adapter converts device coordinates before the UI layer receives an event.

use cranpose_foundation::{PointerEvent, PointerEventKind};
use cranpose_ui_graphics::Point;

let position = Point::new(24.0, 32.0);
let event = PointerEvent::new(PointerEventKind::Down, position, position);

Custom modifier nodes use ModifierNode, ModifierNodeElement and the impl_modifier_node! helper. cranpose-ui supplies Modifier::from_element as the app-facing entry point. See the ModifierNode API, the modifier guide and the crate source.

The feature set is empty. The dependency set stays platform-neutral.
