<h1>DeviceNotifier Class Reference</h1>
<code>from PyKDE4.solid import *</code>
<p>
Inherits: QObject<br />
Namespace: <a href="../solid/Solid.html">Solid</a><br />
<h2>Detailed Description</h2>
<p>This class allow to query the underlying system to obtain information
about the hardware available.
</p>
<p>
It's the unique entry point for hardware discovery. Applications should use
it to find devices, or to be notified about hardware changes.
</p>
<p>
Note that it's implemented as a singleton and encapsulates the backend logic.
