\class QIdleDelegate
\brief The QIdleDelegate class is a virtual class for gathering idle CPU cycles
\inmodule QtProcessManager
You must subclass this class to do anything useful.
The QIdleDelegate is turned on and off by the \l{requestIdleCpu()} function.
The QIdleDelegate should emit the \l{idleCpuAvailable()} signal approximately
once per second when it is turned on.
Subclasses should respect the \l{enabled} property by not generating signals
if the QIdleDelegate is not enabled.
*/
/*!
\property QIdleDelegate::enabled
\brief Boolean value of whether or not this QIdleDelegate should generate signals.
