如何在JavaFX中创建ButtonBar？
以下示例演示了ButtonBar的创建。
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.ButtonBar;
import javafx.scene.control.ButtonBar.ButtonData;
import javafx.scene.control.ToggleButton;
import javafx.scene.control.ToggleGroup;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class ButtonBarExample extends Application {
@Override
public void start(Stage stage) {
//创建切换按钮
ToggleButton button1 = new ToggleButton("Java");
button1.setPrefSize(60, 40);
ToggleButton button2 = new ToggleButton("Python");
button2.setPrefSize(60, 40);
ToggleButton button3 = new ToggleButton("C++");
button3.setPrefSize(60, 40);
//将按钮添加到切换组
ToggleGroup group = new ToggleGroup();
button1.setToggleGroup(group);
button2.setToggleGroup(group);
button3.setToggleGroup(group);
//创建一个ButtonBar-
ButtonBar buttonBar = new ButtonBar();
//将按钮添加到按钮栏
ButtonBar.setButtonData(button1, ButtonData.APPLY);
ButtonBar.setButtonData(button2, ButtonData.APPLY);
ButtonBar.setButtonData(button3, ButtonData.APPLY);
buttonBar.getButtons().addAll(button1, button2, button3);
//将切换按钮添加到窗格中
HBox box = new HBox(5);
box.setPadding(new Insets(50, 50, 50, 150));
box.getChildren().addAll(buttonBar);
box.setStyle("-fx-background-color: BEIGE");
//设置舞台
Scene scene = new Scene(box, 595, 150);
stage.setTitle("Button Bar");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]){
launch(args);
}
}输出结果
