Beschreibung

Description

When alt-dragging (cloning) a shape that has arrows connected to it, the arrows should also be cloned with their bindings updated appropriately.

Current behavior

  • Clone a shape by alt-dragging it
  • The shape is duplicated, but any arrows connected to it are not cloned
  • The cloned shape has no arrow connections

Desired behavior

When alt-dragging a shape to clone it, any arrows connected to that shape should also be cloned. The bindings should be updated to reference both the original and cloned shapes.

Example

Before cloning:

  • Box A → (arrow) → Box B

After alt-dragging Box B to create Box C:

  • Box A → (arrow) → Box B
  • Box A → (arrow) → Box C (newly cloned arrow)

This should work for arrows pointing to the cloned shape, arrows pointing from the cloned shape, or both.

Use case

This would make it much faster to duplicate parts of a diagram while preserving the connections, instead of having to manually recreate the arrows for cloned shapes.

Research-Richtung
Examine the alt drag cloning implementation for shapes in tldraw. Look for the code that handles shape duplication (likely in a handler like `onPointerDown` or `onDrag`). Investigate how arrows are connected to shapes via bindings. Identify where the arrow cloning logic should be triggered during shape duplication. Review any existing tests for cloning behavior. Consider whether the arrow's source and target need to be updated to point to the cloned shape or remain pointing to the original.
