JavaFx - 获取父节点不是Pane的节点或控件的坐标（x，y）
我正在尝试模拟一个弹出式容器，该容器将显示有关正确格式的地址的一些提示。只要addressTextfield获得焦点，弹出窗口就会显示。弹出窗口应显示在addressTextfield下方。问题是，我使用VBox，HBox和FlowPane的组合作为我的布局。默认layoutX和layoutY为零，似乎它们在运行时不会更改。
我的弹出控件
我的地址字段和层次结构
到目前为止我得到了什么......
我的弹出窗口控件保持最佳状态。我尝试将我的弹出窗口layoutXProperty()绑定到addressTextFields layoutXProperty() layoutYProperty() MouseEvent.MOUSE_CLICKED。我尝试在addressTextField上添加MouseLocationProperty，添加MouseEvent.MouseClicked，layoutXProperty()将更新addressTextField并将其绑定到我的弹出窗口package com.strongandwhite.pages.dentistadnstaff;

Pane有什么方法可以得到coverPane相对于我的表格的坐标？
注意：我的弹出式广告已添加到StackPane特定的window.location = "/signin";
上方，该window.location = "/signin?q=1";
位于我的表单之上且全部位于signin下。

答案 0 :(得分：1)
These guys建议您使用以下内容：
Bounds boundsInScene = addressTextField.localToScene(addressTextField.getBoundsInLocal());
然后使用
boundsInScene.getMinX()
boundsInScene.getMinY()
boundsInScene.getMaxX()
boundsInScene.getMaxY()
boundsInScene.getWidth()
boundsInScene.getHeight()
