<title>State Chart with Draggable Link Labels</title>

<div id="sample">

<div id="myDiagramDiv" style="background-color: whitesmoke; border: solid 1px black; width: 100%; height: 400px"></div>
|
||||
<p>
|
||||
This sample is a modification of the <a href="../samples/stateChart.html">State Chart</a> sample that makes use of
|
||||
the LinkLabelDraggingTool that is defined in its own file, as <a href="LinkLabelDraggingTool.ts">LinkLabelDraggingTool.ts</a>.
|
||||
</p>
|
||||
<p>
|
||||
Note that after dragging a link label you can move a node connected by that link and the label maintains the same position
|
||||
relative to the link route. That relative position is specified by the <a>GraphObject.segmentOffset</a> property.
|
||||
This sample also saves any changes to that property by means of a TwoWay <a>Binding</a>.
|
||||
</p>
|
||||
<p>
|
||||
See also the similar <a href="LinkLabelOnPathDragging.html" target="_blank">Link Label On Path Dragging sample</a>,
|
||||
where the label is constrained to remain on the path of the link.
