javafx绑定：文本绑定到两个属性

Question

我想将Text Node的text属性绑定到两个属性，如：

Films

现在，当Available.income更改时，Text节点反映更新，但'now'更改时没有任何反应;

SELECT Films.id AS `Films__id`, Films.name AS `Films__name` 
FROM films Films 
INNER JOIN (SELECT Films.id AS `Films__id` FROM films Films) Films2 ON Films.id = Films2.id 
ORDER BY Films.released DESC

我该如何解决这个问题，谢谢

Answer 1

你可以做到

income.textProperty().bind(Bindings.createStringBinding(() -> 
    available.income.get() + " Income for " + now.getValue().getMonth(),
    available.income, now));
