This is only relevant when the currently executing callback object has its <code>interruptible</code> property set to <code>"off"</code>. The <code>busyaction</code> property of the interrupting callback object indicates whether the interrupting callback is queued (<code>"queue"</code> (default)) or discarded (<code>"cancel"</code>).

<dt><code>hittest</code>: <code>"off"</code> | {<code>"on"</code>}</dt>
<dd><p>Specify whether line processes mouse events or passes them to ancestors of the object. When enabled, the object may respond to mouse clicks by evaluating the <code>"buttondownfcn"</code>, showing the uicontextmenu, and eventually becoming the root <code>"currentobject"</code>. This property is only relevant when the object can accept mouse clicks which is determined by the <code>"pickableparts"</code> property.
