我使用javafx场景构建器创建了接口的fxml文件。 现在我需要在界面上获得按钮位置，但是当我调用按钮方法来获取X，Y坐标时，返回的值是0.0 !! 谢谢你提前。

您好，感谢您的回复。 我用以下代码解决了它。
Button bt;
Bounds localBounds = bt.localToScene(bt.getBoundsInLocal());
double popupX = bt.getScene().getWindow().getX() + localBounds.getMaxX();
double popupY = bt.getScene().getWindow().getY() + localBounds.getMaxY();
我希望代码可以对其他人有所帮助。
