pulltorefresh }> add-on - Vaadin Add-on Directory
An extension to Vaadin that provides a Java API for the pulltorefresh.js JS library.
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);
```
