<p>FLprintk2 —
A FLTK opcode that prints a new value every time a control-rate variable changes.

<div class="refsect1" title="Description">
<a id="idp21552600"></a>
<h2>Description</h2>
<p>
<span class="emphasis"><em>FLprintk2</em></span> is similar to <a class="link" href="FLprintk.html" title="FLprintk"><em class="citetitle">FLprintk</em></a> but shows a k-rate variable's value only when it changes.
</p>

<div class="refsect1" title="Syntax">
<a id="idp21553880"></a>
<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>FLprintk2</strong></span> kval, idisp</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="idp21554920"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>idisp</em></span> -- a handle value that was output from a previous instance of the <a class="link" href="FLvalue.html" title="FLvalue"><em class="citetitle">FLvalue</em></a> opcode to display the current value of the current valuator in the <span class="emphasis"><em>FLvalue</em></span> widget itself. If the user doesn't want to use this feature that displays current values, it must be set to a negative number by the user.

<div class="refsect1" title="Performance">
<a id="idp21556704"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>kval</em></span> -- k-rate signal to be displayed.
</p>
<p>
<span class="emphasis"><em>FLprintk2</em></span> is similar to <a class="link" href="FLprintk.html" title="FLprintk"><em class="citetitle">FLprintk</em></a>, but shows the k-rate variable's value only each time it changes. Useful for monitoring MIDI control changes when using sliders. It should be used for debugging purposes only, since it slows-down performance.
