在JavaFx Label中显示更改的值 [英] Displaying changing values in JavaFx Label

问题描述

在JavaFX中，如何使用标签显示随时间不断变化的值？

In JavaFX, how can I display values which continuously change with time using "label" ?

推荐答案

有很多方法可以实现这一点，最方便的是使用JavaFX的DataBinding机制：

There are numerous ways to achieve that, the most convenient would be to use JavaFX's DataBinding mechanism:

// assuming you have defined a StringProperty called "valueProperty"
Label myLabel = new Label("Start");
myLabel.textProperty().bind(valueProperty);

这样，每次通过调用set方法更改valueProperty时，标签的文本都会更新。

This way, every time your valueProperty gets changed by calling it's set method, the label's text is updated.
