To capture drag there is EnableDragEvent() that you will have to call in constructL() and then in HandlePointerEventL() you will receive this event TPointerEvent::EDrag.

These events are only received after button 1 is down. Button1down will provide you with the initial position and EDrag will give you the next pointerposition and when you lift your stylus EButton1Up wil be called.

Thanks for replying.

I want each x and y coordinate of line from intial point to the point where i left it .
can u tell me any logic to store that point.like in array ,can we fetch each point on array?

you can create an RPointerArray<TPointerEvent> of this type and can store all the pointer position from EButton1Down -> EDrag -> EButton1Up in this order.
