class TTimer: public TSysEvtHandler

TTimer

Handles synchronous and a-synchronous timer events. You can use
this class in one of the following ways:
- Sub-class TTimer and override the Notify() method.
- Re-implement the TObject::HandleTimer() method in your class
and pass a pointer to this object to timer, see the SetObject()
method.
- Pass an interpreter command to timer, see SetCommand() method.
- Create a TTimer, connect its Timeout() signal to the
appropriate methods. Then when the time is up it will emit a
Timeout() signal and call connected slots.

Minimum timeout interval is defined in TSystem::ESysConstants as
kItimerResolution (currently 10 ms).

Signal/slots example:
TTimer *timer = new TTimer();
timer->Connect("Timeout()", "myObjectClassName",
myObject, "TimerDone()");
timer->Start(2000, kTRUE);   // 2 seconds single-shot

 Timeout signal is emitted repeadetly with minimum timeout
 timer->Start(0, kFALSE);
