Detailed Description

KArtsFloatWatch offers an easy way to watch aRts streams via Qt signals.

For instance, if you have an object of the following type:

 interface StereoVolumeControl : StereoEffect {
   attribute float scaleFactor;
   readonly attribute float currentVolumeLeft;
   readonly attribute float currentVolumeRight;
 };

and you want to get notified when scaleFactor changes, you could do it like this:

   StereoVolumeControl stereoVolumeControl = ...;
   KArtsFloatWatch *w = new KArtsFloatWatch(stereoVolumeControl, "scaleFactor_changed", this);
   connect(w, SIGNAL(valueChanged(float)), this, SLOT(setValue(float)));
