If I ever write a real application, I'm most definitely will use EasyBind. But
this is for sharping up Agenda in JFXtras. I try to minimize the dependencies.

Just a side note, you could use
EasyBind.map(heightProperty(), value ->
NodeUtil.snapXY(value.doubleValue() * 0.2));
instead of
snap(heightProperty().multiply(0.2))
and you don't need your custom DoubleBinding implementation. But note
that it returns Binding, not DoubleBinding.
EasyBin
Yeah, and you could also eliminate "Observable... dependencies" from
snap's signature, since now you are not using them to invalidate your
binding.

Found it! Slightly different DoubleBinding was required (copied it from negate).
private DoubleBinding snap(final ObservableNumberValue value, final
Observable... dependencies) {
return new DoubleBinding() {
{
super.bind(value);
}
Hi Tom,
it seems to me that in your custom DoubleBinding implementation
`other` is not its dependency, thus it does not react to it's
invalidations.

I came up with this:
startXProperty().bind( *snap(*heightProperty().multiply(0.2)) )
And then:
private DoubleBinding snap(final ObservableNumberValue other, final
Observable... dependencies) {
return new DoubleBinding() {
{
super.bind(dependencies);
I would like to add a snap method to a calculating bind. For example:
startXProperty().bind( heightProperty().multiply(0.2).snap() )
One option would be to extend the DoubleProperty that is used for the
heightProperty, but that would only work for situations where I am the owner of
the source
