<p>FLprintk —
A FLTK opcode that prints a k-rate value at specified intervals.
</p>
</div>
<div class="refsect1" title="Description">
<a id="idp21576144"></a>
<h2>Description</h2>
<p>
<span class="emphasis"><em>FLprintk</em></span> is similar to <a class="link" href="printk.html" title="printk"><em class="citetitle">printk</em></a> but shows values of a k-rate signal in a text field instead of on the console.
</p>
</div>
<div class="refsect1" title="Syntax">
<a id="idp21595040"></a>
<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>FLprintk</strong></span> itime, kval, idisp</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="idp21596056"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>itime</em></span> -- how much time in seconds is to elapse between updated displays.
</p>
<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.
</p>
</div>
<div class="refsect1" title="Performance">
<a id="idp21598320"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>kval</em></span> -- k-rate signal to be displayed.
</p>
<p>
<span class="emphasis"><em>FLprintk</em></span> is similar to <a class="link" href="printk.html" title="printk"><em class="citetitle">printk</em></a>, but shows values of a k-rate signal in a text field instead of showing it in the console. The <span class="emphasis"><em>idisp</em></span> argument must be filled with the <span class="emphasis"><em>ihandle</em></span> return value of a previous <span class="emphasis"><em>FLvalue</em></span> opcode. While <span class="emphasis"><em>FLvalue</em></span> should be placed in the header section of an orchestra inside an <a class="link" href="FLpanel.html" title="FLpanel"><em class="citetitle">FLpanel</em></a>/<a class="link" href="FLpanelEnd.html" title="FLpanelEnd"><em class="citetitle">FLpanelEnd</em></a> block, <span class="emphasis"><em>FLprintk</em></span> must be placed inside an instrument to operate correctly. For this reason, it slows down performance and should be used for debugging purposes only.
