|
This sample is a simplified version of the <a href="../samples/draggableLink.html">Draggable Link</a> sample.
|
|
Links are not draggable, there are no custom <a>Adornment</a>s, nodes are not rotatable, and links
|
|
do not have text labels.
|
|
</p>
|
|
<p>
|
|
Its purpose is to demonstrate the <a href="SnapLinkReshapingTool.ts">SnapLinkReshapingTool</a>,
|
|
an extension of <a>LinkReshapingTool</a> that snaps each dragged reshape handle of selected Links to
|
|
the nearest grid point.
|
|
</p>
|
|
<p>
|
|
Note how the "LinkReshaped" DiagramEvent listener changes the <a>Link.routing</a> of the reshaped Link,
|
|
so that it is no longer AvoidsNodes routing but simple Orthogonal routing.
|
|
This combined with <a>Link.adjusting</a> being End permits the middle points of the link route to be
|
|
retained even after the user moves or resizes nodes.
|
|
Furthermore there is a TwoWay <a>Binding</a> on <a>Link.routing</a>, so that the model remembers
|
|
whether the link route had ever been reshaped manually.
