<a href="classKArtsFloatWatch-members.html">List of all members.</a><hr><a name="_details"></a><h2>Detailed Description</h2>
<a class="el" href="classKArtsFloatWatch.html">KArtsFloatWatch</a> offers an easy way to watch aRts streams via <a class="elRef" doxygen="qt.tag:" href="qt.html">Qt</a> signals.
<p>
For instance, if you have an object of the following type:<p>
<div class="fragment"><pre class="fragment"> interface StereoVolumeControl : StereoEffect {
attribute <span class="keywordtype">float</span> scaleFactor;
readonly attribute <span class="keywordtype">float</span> currentVolumeLeft;
readonly attribute <span class="keywordtype">float</span> currentVolumeRight;
};
</pre></div><p>
and you want to get notified when scaleFactor changes, you could do it like this:<p>
<div class="fragment"><pre class="fragment"> StereoVolumeControl stereoVolumeControl = ...;
<a class="code" href="classKArtsFloatWatch.html">KArtsFloatWatch</a> *w = <span class="keyword">new</span> <a class="code" href="classKArtsFloatWatch.html#f6dac0b28d9e670b79a5c1e21f6ddd6f">KArtsFloatWatch</a>(stereoVolumeControl, <span class="stringliteral">"scaleFactor_changed"</span>, <span class="keyword">this</span>);
<a class="codeRef" doxygen="qt.tag:" href="qobject.html#connect">connect</a>(w, SIGNAL(<a class="code" href="classKArtsFloatWatch.html#4744b1f7ab4ebcaa9d308a61f636ed6a">valueChanged</a>(<span class="keywordtype">float</span>)), <span class="keyword">this</span>, SLOT(setValue(<span class="keywordtype">float</span>)));
