Just do what Thomas has suggested. Listen for ScrollEvent and do
void onScroll(ScrollEvent e) {
sendScrollHeightToServerTimer.schedule(100);
}
If the timer is not yet scheduled it will be scheduled to execute in 100ms
in the future. However if a new scroll event occurs within that 100ms the
timer will reset and again wait 100ms. So whenever scrolling is stopped for
at least 100ms the timer fires and the timer code executes to read the
scroll height and send it to your server.
