add listeners item's checkedproperty()s:
@fxml public void initalize() throws ioexception { tablecolumn<trafficvolume, string> tvids = new tablecolumn<trafficvolume, string>("tv-id"); tablecolumn<trafficvolume, string> flvl = new tablecolumn<trafficvolume, string>("flight level"); tablecolumn<trafficvolume, boolean> checkedcol = new tablecolumn<trafficvolume, boolean>("active"); tabletvid.setitems(list); (trafficvolume trafficvolume : list) { trafficvolume.checkedproperty().addlistener((obs, waschecked, isnowchecked) -> { system.out.println("checked property " + trafficvolume.getname() + " changed "+waschecked + " " + isnowchecked); } } // ... }
