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)));
