[vtkusers] timer example

[Dominik Szczerba]

Hi,

The following is a simple example of a timer event invoked over a mouse move:

class MyIdleCommand : public vtkCommand{
public:
  void Execute(vtkObject* caller, unsigned long eventId, void* callData){
	 cerr << "idle()" << endl;
  }
};

in main:
...
MyIdleCommand* command3 = new MyIdleCommand;
...
iren->CreateTimer(VTKI_TIMER_UPDATE);
iren->AddObserver(vtkCommand::MouseMoveEvent, command3);


It works just fine, but is not much usefull: I want to figure out how to make 
it call my command every N miliceconds instead. I tried to replace 
MouseMoveEvent with e.g. TimerEvent but it doesnt work.

Note that

int id = iren->CreateRepeatingTimer(10L);
  
segfaults, as once reported.

I cannot google anything out. I would appreciate if anyone could give me a 
short hint how to get it running.

Regards,
Dominik
