以下是一个简单的示例，实现您想要的功能。更专业的方式是实现一个自定义的皮肤。也许其他人会分享它。
App:
import javafx.application.Application;import javafx.scene.Scene;import javafx.scene.control.CheckBox;import javafx.scene.control.ContentDisplay;import javafx.scene.control.Label;import javafx.scene.input.MouseButton;import javafx.scene.layout.Pane;import javafx.scene.text.TextAlignment;import javafx.stage.Stage;public class App extends Application {@Overridepublic void start(Stage stage) {// 首先创建一个分离的标签：Label label = new Label("Am efectuat toate");// 创建一个没有文本的复选框CheckBox checkBox = new CheckBox();// 将复选框放置为标签的图形节点：label.setGraphic(checkBox);// 将框放在标签的顶部显示：label.setContentDisplay(ContentDisplay.TOP);// 在标签的主鼠标按钮单击时切换复选框的选择属性：label.setOnMouseClicked(mouseEvent -> {if (mouseEvent.getButton() == MouseButton.PRIMARY)checkBox.setSelected(!checkBox.isSelected());});// 如果您想要在第二行中有最后一个词“toate”：label.setWrapText(true);label.setMaxWidth(80);label.setTextAlignment(TextAlignment.CENTER);// 创建场景并显示：Pane root = new Pane();root.getChildren().add(label);stage.setScene(new Scene(root, 120, 60));stage.show();}public static void main(String[] args) {launch();}}

Below is one simple example of achieving what you want. The more professional way would be to implement a custom skin. Maybe someone else will share it.
App:
import javafx.application.Application;import javafx.scene.Scene;import javafx.scene.control.CheckBox;import javafx.scene.control.ContentDisplay;import javafx.scene.control.Label;import javafx.scene.input.MouseButton;import javafx.scene.layout.Pane;import javafx.scene.text.TextAlignment;import javafx.stage.Stage;public class App extends Application {@Overridepublic void start(Stage stage) {// Create a separated label at first:Label label = new Label("Am efectuat toate");// Create a check box without a textCheckBox checkBox = new CheckBox();// Put the check box as the graphic node of the label:label.setGraphic(checkBox);// Put the box on top of the label:label.setContentDisplay(ContentDisplay.TOP);// Toggle selected property of checkbox on label primary mouse button click:label.setOnMouseClicked(mouseEvent -> {if (mouseEvent.getButton() == MouseButton.PRIMARY)checkBox.setSelected(!checkBox.isSelected());});// If you want to have the last word "toate" in a second line:label.setWrapText(true);label.setMaxWidth(80);label.setTextAlignment(TextAlignment.CENTER);// Create scene and show:Pane root = new Pane();root.getChildren().add(label);stage.setScene(new Scene(root, 120, 60));stage.show();}public static void main(String[] args) {launch();}}
