Re: How to detect the scrollpanel is still scrolling or not in GWT?

Is there any way to implement scroll bar with mouse listeners? Bottom line, I want to send the request while doing scrolling. I meant last scrolling height to server if scrolling is delayed for 100 ms or stopped.

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.
