FXML生成的JavaFX更改节点到另一个节点

Question

我有一个由 fxml 文件定义的复杂 UI。有很多 stockTextField我想更改为ControlsFX库提供的更高级版本（可清除的文本字段）。

问题：

ControlsFX 用于CustomTextField提供高级功能，但它只能被初始化，TextFields.createClearableTextField()只能从代码中调用。

我正在寻找一种TextField将通过 FXMLCustomTextField初始化的 s 与从代码初始化的 s 交换的方法，以便这些新控件将保留在 FXML 中定义的所有布局属性。

CustomTextField在 FXML 中 定义也无济于事，因为默认情况下它是无用的。CustomTextField获得了private static void setupClearButtonField(TextField inputField, ObjectProperty<Node> rightProperty)我无法调用的功能，因为它是私有的。

ControlsFX 代码：

/**

 * Creates a TextField that shows a clear button inside the TextField (on

 * the right hand side of it) when text is entered by the user.

 */

public static TextField createClearableTextField() {

    CustomTextField inputField = new CustomTextField();

    setupClearButtonField(inputField, inputField.rightProperty());

    return inputField;

}

/**

 * Creates a PasswordField that shows a clear button inside the PasswordField

 * (on the right hand side of it) when text is entered by the user.

 */

public static PasswordField createClearablePasswordField() {

    CustomPasswordField inputField = new CustomPasswordField();

    setupClearButtonField(inputField, inputField.rightProperty());

    return inputField;

}

private static void setupClearButtonField(TextField inputField, ObjectProperty<Node> rightProperty) {

    inputField.getStyleClass().add("clearable-field"); //$NON-NLS-1$

    Region clearButton = new Region();

    clearButton.getStyleClass().addAll("graphic"); //$NON-NLS-1$

    StackPane clearButtonPane = new StackPane(clearButton);

    clearButtonPane.getStyleClass().addAll("clear-button"); //$NON-NLS-1$

    clearButtonPane.setOpacity(0.0);

    clearButtonPane.setCursor(Cursor.DEFAULT);

    clearButtonPane.setOnMouseReleased(e -> inputField.clear());

    clearButtonPane.managedProperty().bind(inputField.editableProperty());

    clearButtonPane.visibleProperty().bind(inputField.editableProperty());

    rightProperty.set(clearButtonPane);

    final FadeTransition fader = new FadeTransition(FADE_DURATION, clearButtonPane);

    fader.setCycleCount(1);

您可以fx:factory按照FXML 简介中的说明使用。<?xml version="1.0" encoding="UTF-8"?><?import javafx.scene.layout.StackPane?><?import org.controlsfx.control.textfield.TextFields?><StackPane xmlns="http://javafx.com/javafx" xmlns:fx="http://javafx.com/fxml"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;fx:controller="com.example.Controller">&nbsp; &nbsp; <TextFields fx:id="field" fx:factory="createClearableTextField"/></StackPane>然后在控制器中使用它：package com.example;import javafx.fxml.FXML;import javafx.scene.control.TextField;public class Controller {&nbsp; &nbsp; @FXML private TextField field;}注意：如果您使用的是 IntelliJ，它会发出一条错误消息：无法将 org.controlsfx.control.textfield.TextFields 设置为字段“字段”在 FXML 文件中，但是当我运行一个测试项目时，一切正常。
