Developer Guide

Getting started

Here is a simple example on how to try out the add-on component:

// Initialize the scroll panel with a inner component bigger than the available space
final ScrollablePanel scrollablePanel = new ScrollablePanel(scrollContent);
scrollablePanel.setSizeFull();

scrollablePanel.setScrollTop(100); // set some vertical scroll position

// add a scroll listener
scrollablePanel.addScrollListener(new ScrollListener() {
	
	@Override
	public void onScroll(final ScrollEvent event) {
		Notification.show("Scrolled: " + event.getScrollData().toString());
	}
});
