Interface Drag<M>

A drag behavior: Dragology's DragBehavior, reactive and parametric in the MODEL M (positions are just M = Vec).

interface Drag<M> {
    at: Read<V>;
    drop: Read<M>;
    gap: Read<number>;
    preview: Read<M>;
}

Properties

at: Read<V>

Where the dragged handle sits this frame (the renderer floats it here).

drop: Read<M>

Model committed on release.

gap: Read<number>

Residual |pointer − achievable|; combinators arbitrate on this.

preview: Read<M>

Model rendered this frame (non-dragged elements reflow toward this).
