java - javafxでスイッチボタンを作成するにはどうすればよいですか?

Question

上記のようなスイッチボタンを作成したい私は、このウィジェットSwitchbutton を取得していたswt開発者です。javafxで同様のものを使用できますか

Answer 1

First inclination is to extend the JavaFX Label and add a Button as a graphic and a SimpleBooleanProperty for listening. Set an ActionEvent handler on the button that toggles the Label's text, style, and graphic content alignment. The code below will get you started and you can play with styling and bounding.

package switchbutton;

import javafx.beans.property.SimpleBooleanProperty;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.control.Button;
import javafx.scene.control.ContentDisplay;
import javafx.scene.control.Label;

public class SwitchButton extends Label
{
    private SimpleBooleanProperty switchedOn = new SimpleBooleanProperty(true);

    public SwitchButton()
    {
        Button switchBtn = new Button();
        switchBtn.setPrefWidth(40);
        switchBtn.setOnAction(new EventHandler<ActionEvent>()
        {
            @Override
            public void handle(ActionEvent t)
            {
                switchedOn.set(!switchedOn.get());
            }
        });

        setGraphic(switchBtn);

        switchedOn.addListener(new ChangeListener<Boolean>()
        {
            @Override
            public void changed(ObservableValue<? extends Boolean> ov,
                Boolean t, Boolean t1)
            {
                if (t1)
                {
                    setText("ON");
                    setStyle("-fx-background-color: green;-fx-text-fill:white;");
                    setContentDisplay(ContentDisplay.RIGHT);
                }
                else
                {
                    setText("OFF");
                    setStyle("-fx-background-color: grey;-fx-text-fill:black;");
                    setContentDisplay(ContentDisplay.LEFT);
                }
            }
        });

        switchedOn.set(false);
    }

    public SimpleBooleanProperty switchOnProperty() { return switchedOn; }
}
