externalXYWH

In some cases, you need to draw something related to the element, but it does not belong to the element itself. And it is also interactive, you can select element by clicking on it. E.g. the title of the group element. In this case, we need to store this kind of external xywh in order to do hit test. This property should not be synced to the doc. This property should be updated every time it gets rendered.

Returns

Inherited from

SurfaceGroupLikeModel.responseBound

Defined in

packages/framework/block-std/dist/gfx/model/surface/element-model.d.ts:60

---

responseExtension

Defines the extension of the response area beyond the element's bounding box. This tuple specifies the horizontal and vertical margins to be added to the element's bound.

The first value represents the horizontal extension (added to both left and right sides), and the second value represents the vertical extension (added to both top and bottom sides).

The response area is computed as: [x - horizontal, y - vertical, w + 2 * horizontal, h + 2 * vertical].

Example:

• xywh: [0, 0, 100, 100], responseExtension: [10, 20] Resulting response area: [-10, -20, 120, 140].
• responseExtension: [0, 0] keeps the response area equal to the bounding box.
