我有一個由 fxml 文件定義的復雜 UI。有很多 stockTextField我想更改為ControlsFX庫提供的更高級版本（可清除的文本字段）。問題：ControlsFX 用于CustomTextField提供高級功能，但它只能被初始化，TextFields.createClearableTextField()只能從代碼中調用。我正在尋找一種TextField將通過 FXMLCustomTextField初始化的 s 與從代碼初始化的 s 交換的方法，以便這些新控件將保留在 FXML 中定義的所有布局屬性。CustomTextField在 FXML 中 定義也無濟于事，因為默認情況下它是無用的。CustomTextField獲得了private static void setupClearButtonField(TextField inputField, ObjectProperty<Node> rightProperty)我無法調用的功能，因為它是私有的。ControlsFX 代碼：/** * 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 簡介中的說明使用。
<?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"
fx:controller="com.example.Controller">
<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 {
@FXML private TextField field;
}
注意：如果您使用的是 IntelliJ，它會發出一條錯誤消息：
無法將 org.controlsfx.control.textfield.TextFields 設置為字段“字段”
在 FXML 文件中，但是當我運行一個測試項目時，一切正常。
