JavaFX 检测舞台屏幕位置的变化

Question

JavaFX 中有没有办法检测舞台/窗口位置相对于屏幕何时发生变化？

我可以检测到何时调整舞台大小，但无法检测到何时重新定位舞台。

Answer 1

您可以使用xProperty和 yProperty 窗口。

The horizontal location of this Stage on the screen. Changing this attribute will move the Stage horizontally. Changing this attribute will not visually affect a Stage while fullScreen is true, but will be honored by the Stage once fullScreen becomes false.

stage.xProperty().addListener((obs, oldVal, newVal) -> System.out.println("X: " + newVal));
stage.yProperty().addListener((obs, oldVal, newVal) -> System.out.println("Y: " + newVal));
