pulltorefresh }> add-on: An extension to Vaadin that provides a Java API for pulltorefresh JS library. The “pull to refresh” gesture triggers a callback on the Java side, where you can for example check for new data from the backend.

Contains both extended version of Scroller component and a VerticalLayout that configures the body element.

Note that this add-on only works on touch devices. If your app is for desktop devices only, ensure you have another UI pattern for those on desktop.

Usage:

        VerticalLayout layout = new VerticalLayout();
        for(int i = 0; i< 100; i++) {
            layout.add(new Paragraph("This is a paragraph "+i+" in scroller."));
        }
        Scroller scroller = new PullToRefreshScroller(() -> {
            layout.addComponentAsFirst(new Paragraph("Refreshed at "+ LocalTime.now()));
        });
        scroller.setContent(layout);
