Question

我正在尝试模拟一个弹出容器，它会显示一些关于正确地址格式的提示。只要 addressTextfield 获得焦点，就会显示弹出窗口。弹出窗口应出现在 addressTextfield 下方。问题是，我在布局中使用了 VBox、HBox 和 FlowPane 的组合。默认的 layoutX 和 layoutY 是零，看起来它们在运行时不会改变。

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 Popup 控件保持在顶部。我尝试将我的弹出窗口 layoutXProperty() 绑定到 addressTextFields 的 layoutXProperty()same in layoutYProperty()。我尝试在 addressTextField 上添加一个 MouseEvent.MOUSE_CLICKED，添加一个将在 MouseEvent.MouseClicked 上更新的 MouseLocationProperty，并将其绑定到我的弹出窗口的 layoutXProperty()。但是仍然没有让它出现在 addressTextField.

有什么方法可以获取 addressTextField 相对于我的表单的坐标吗？

注意：我的弹出窗口添加在 Pane 特别是 coverPane 上面，它们都在 StackPane.

Answer 1

建议您使用类似的东西：

Bounds boundsInScene = addressTextField.localToScene(addressTextField.getBoundsInLocal());

然后使用

boundsInScene.getMinX()
boundsInScene.getMinY()
boundsInScene.getMaxX()
boundsInScene.getMaxY()
boundsInScene.getWidth()
boundsInScene.getHeight()

获取组件相对于场景的值

JavaFx - 获取其父节点不是 Pane 的节点或控件的坐标 (x,y)

JavaFx - Get the coordinates(x,y) of a node or control whose parent is not a Pane
