java - Spinner<Integer> bind to IntegerProperty -

-

i want use fx8 spinner control, want bind source integerproperty

int min = 0; int max = 5000; int step = 500; integerproperty integerproperty = new simpleintegerproperty();  spinner<integer> spinner = new spinner<>(min, max, step);

i understand binding set via binding valueproperty in value factory. expects property<integer> , cannot find way cast between integerproperty , property<integer>.

obviously below generates compiler error:

spinner.getvaluefactory().valueproperty().bindbidirectional(integerproperty);

do need manually assign change listener both directions? surely there neater solution using valueproperty, cannot have been unforeseen situation.

you can wrap objectproperty:

objectproperty<integer> objectprop = new simpleobjectproperty<>(min); integerproperty integerproperty = integerproperty.integerproperty(objectprop);  spinner<integer> spinner = new spinner<>(min, max, step);  spinner.getvaluefactory().valueproperty().bindbidirectional(objectprop);

integerproperty.integerproperty creates property that's bidirectionally connected property wraps.
