javafx 2 - How to keep a TableView's selection when focus is lost? -

how can keep tableview's selection when focus lost windows?

when focus window lost, selected item still visibly selected in window; however, cannot find way access selected object controllers.

i have tried using tableview's methods getselectionmodel().selecteditemproperty().get() , getselectionmodel().getselecteditem() both of these return null if focus window and/or table lost.

use variable , set in change listener. use labels debugging.

    table.getselectionmodel().getselectedcells().addlistener(new listchangelistener<tableposition>() {         @override         public void onchanged(listchangelistener.change<? extends tableposition> c) {             label1.settext(string.valueof(c.getlist().get(0).getrow()));         }     }); 

java 8

    table.getselectionmodel().getselectedcells().addlistener((listchangelistener.change<? extends tableposition> c) -> {         label1.settext(string.valueof(c.getlist().get(0).getrow()));     });
