Detailed Description

An engine that produces AnchorDefinition.

Attributes

• for: SidedMetaObject the metaobject and side of the key (required)
• name: String name of the key
• object: ConcreteObject for the key, otherwise the object from the context will be used
• both_sides: Boolean if set to true, keys for both sides are created.
• Other depending on the `type`.

Multiple SidedMetaObject and ConcreteObject can be defined at one for a single anchor.

Contents

Depends on the `type`.

Result

An AnchorDefinition for each side an concrete object.

---

Types

rectangular

On the bounding rectangle of the widget.

center

At the center of the widget.

circular

Located circularly from the center, accepts a `radius` parameter.

directional

On a side of the widget with parameters `kind` of type DirectionalAnchorKind and a `gap` from the widget.

vmd

A VMD anchor from VL with a `kind` parameter. Similar to the directional anchor, but computes a different place for each edge.

shape

Attached to the shape. See ShapeAwareAnchor.

rotated

Rotated anchor (RotateWidget.RotateAnchor#RotateAnchor(boolean, RotateAnchorType). Accepts as parameters `update` (true by default) and `direction`.
