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>).

</dd>
<dt><code>hittest</code>: <code>"off"</code> | {<code>"on"</code>}</dt>
<dd><p>Specify whether uicontrol 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.

By default <code>interruptible</code> is <code>"on"</code> and callbacks that make use of <code>drawnow</code>, <code>figure</code>, <code>waitfor</code>, <code>getframe</code> or <code>pause</code> functions are eventually interrupted.

<dd><p>Specify whether uicontrol will accept mouse clicks. By default, <code>pickableparts</code> is <code>"visible"</code> and only visible parts of the uicontrol or its children may react to mouse clicks. When <code>pickableparts</code> is <code>"all"</code> both visible and invisible parts (or children) may react to mouse clicks. When <code>pickableparts</code> is <code>"none"</code> mouse clicks on the object are ignored and transmitted to any objects underneath this one. When an object is configured to accept mouse clicks the <code>"hittest"</code> property will determine how they are processed. See <a href="#XREFuicontrolhittest">hittest property<!-- /@w --></a>.
