<p>
This sample demonstrates the different values of <a>ToolManager.gestureBehavior</a>.
</p>
<p>
<ul>
<li><a>ToolManager,GestureZoom</a> is the default value: Pinch gestures will zoom the Diagram.
<li><a>ToolManager,GestureNone</a>: Pinch gestures zoom the browser page instead of the Diagram.
<li><a>ToolManager,GestureCancel</a>: Pinch gestures will do nothing.
</ul>
</p>
<p>
Set the value for the Diagram below:
</p>
<p><label><input type="radio" id="GestureZoom" onclick="changegestureBehavior(this.id)" name="group1"><code>go.ToolManager.GestureZoom;</code></label>
<p><label><input type="radio" id="GestureCancel" onclick="changegestureBehavior(this.id)" name="group1" checked="checked"><code>go.ToolManager.GestureCancel;</code></label>
