How to create infinite SpinSelect using domino-ui

Question

When creating a domino-ui horizontal spin select like the following

HSpinSelect<Long>spRepeat = HSpinSelect.create();

Is there a way to make it infinite? so the user can keep clicking on next and get a new long value every time without a limit.

Answer 1

What you can do in this case is starting with some number of long elements that is greater than 1, then you can add a selectionHandler that will check if you are about to hit the limit then you add more spin items.

HSpinSelect<Long> spin = HSpinSelect.create();
LongStream.range(0, 10).forEach(value -> {
    spin.appendChild(SpinItem.create(value, Elements.div().textContent(String.valueOf(value)).element()));
});

spin.addSelectionHandler(selectedItem -> {
    long lastValue = spin.getItems().get(spin.getItems().size() - 1).getValue();
    if(selectedItem.getValue() < (lastValue - 2)){
        LongStream.range(lastValue+1, lastValue+10).forEach(value -> {
            spin.appendChild(SpinItem.create(value, Elements.div().textContent(String.valueOf(value)).element()));
        });
    }
});
