Hi,
 
The first thing to read would be:
 
http://www.qnx.com/developers/docs/6.4.0/photon/prog_guide/events.html
 
It details the events, and how to use them.  Some widgets, like PtContainer contain specific callbacks.
 
I guess if each widget had a Pt_CB_RAW and you filtered for pointer and boundary events, it would accomplish what you 
desire.
 
Regards,
-Derek

Hi,

I want to track the movement of mouse when scrolled across different widgets in a window. Is there an event to intimate 
it? If yes, then, is the same possible if I arm a widget and drag the pointer outside the boundary of the armed widget 
and over the other widgets??

Thanks,
Lakshminarayanan.R
