以下是您要翻译的内容：

使用单选按钮更改绘制模式

在这种方法中，Box 实例使用单选按钮更改其 DrawMode。

这是一个可以尝试的 JavaFX 单一类。

App.java

public class App extends Application {
    
    @Override
    public void start(Stage stage) {

        var perspective = new PerspectiveCamera(true);
        perspective.setNearClip(0.1);
        perspective.setFarClip(500);
        perspective.setTranslateZ(-150);
        
        Shape3D cube = new Box(50, 50, 50);
        cube.setCullFace(CullFace.NONE);
        cube.setMaterial(new PhongMaterial(Color.CORAL));

        var toggleGroup = new ToggleGroup();
        var solid = new RadioButton("实心");
        solid.setToggleGroup(toggleGroup);
        solid.setSelected(true);
        var wire = new RadioButton("线框");
        wire.setToggleGroup(toggleGroup);

        var hBox = new HBox(solid, wire);

        toggleGroup.selectedToggleProperty().addListener((o) -> {
            Toggle selectedToggle = toggleGroup.getSelectedToggle();

            if (selectedToggle == solid) {
                cube.setDrawMode(DrawMode.FILL);
            }
            if (selectedToggle == wire) {
                cube.setDrawMode(DrawMode.LINE);

            }

        });

        var group3d = new Group(perspective, cube);

        var subscene = new SubScene(group3d, 300, 400, true, SceneAntialiasing.BALANCED);
        subscene.setCamera(perspective);

        var stack = new StackPane(subscene, hBox);

        stage.setScene(new Scene(stack, 300, 400));
        stage.show();
    }

    public static void main(String[] args) {
        launch();
    }

}

public class App extends Application {
@Override
public void start(Stage stage) {
var perspective = new PerspectiveCamera(true);
perspective.setNearClip(0.1);
perspective.setFarClip(500);
perspective.setTranslateZ(-150);
Shape3D cube = new Box(50, 50, 50);
cube.setCullFace(CullFace.NONE);
cube.setMaterial(new PhongMaterial(Color.CORAL));
var toggleGroup = new ToggleGroup();
var solid = new RadioButton("solid");
solid.setToggleGroup(toggleGroup);
solid.setSelected(true);
var wire = new RadioButton("wireframe");
wire.setToggleGroup(toggleGroup);
var hBox = new HBox(solid, wire);
toggleGroup.selectedToggleProperty().addListener((o) -> {
Toggle selectedToggle = toggleGroup.getSelectedToggle();
if (selectedToggle == solid) {
cube.setDrawMode(DrawMode.FILL);
}
if (selectedToggle == wire) {
cube.setDrawMode(DrawMode.LINE);
}
});
var group3d = new Group(perspective, cube);
var subscene = new SubScene(group3d, 300, 400, true, SceneAntialiasing.BALANCED);
subscene.setCamera(perspective);
var stack = new StackPane(subscene, hBox);
stage.setScene(new Scene(stack, 300, 400));
stage.show();
}
public static void main(String[] args) {
launch();
}
