Module drag 

Renderer-neutral node dragging helpers.

These helpers turn canvas-space drag intent into normal graph transactions without depending on pointer capture, DOM state, windowing, or renderer APIs.

Structs

NodeDragActivationInput

Screen-space input for deciding whether a node drag should activate.

NodeDragItem

One node movement inside a drag plan.

NodeDragPlan

Planned node drag transaction.

NodeDragRequest

Canvas-space request for moving a primary node to a target position.

NodeNudgePlan

Planned keyboard nudge transaction.

NodeNudgeRequest

Request for nudging the current selected nodes.

PointerGestureClaimInput

Input for resolving which headless pointer gesture should claim a drag start.

Enums

NodeNudgeDirection

Keyboard nudge direction.

PointerGestureClaim

Which runtime gesture should own the current pointer drag.

Constants

NODE_DRAG_TRANSACTION_LABEL

Default transaction label used for committed node drag updates.

NODE_NUDGE_TRANSACTION_LABEL

Default transaction label used for committed keyboard nudge updates.

Functions

node_drag_threshold_met

Returns whether a pointer movement should start a node drag.

plan_node_drag

Plans a node drag update without mutating the graph.

plan_node_nudge

Plans a keyboard nudge update for the currently selected nodes without mutating the graph.
