如何从Java类获取FXML文件中定义的按钮位置
[英]How to Get Button Position defined in FXML File from java class
问题描述
我使用javafx场景构建器为接口创建了fxml文件。 现在我需要获取接口上的按钮位置，但是当我调用button方法以获取X，Y坐标时，返回的值为0.0！ 提前致谢。

您好，感谢您的答复。 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。
