Reading Special MouseButtons

问题

I am interested in capturing input from the explorer mouse buttons (the special buttons on the side of mice normally used to go forward and back on web browsers).

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;
import javafx.scene.input.MouseButton;
import static java.lang.System.*;

public class MouseThing extends Application
{
    @Override
    public void start(Stage stage) throws Exception
    {
        Pane pane = new Pane();

        pane.setOnMousePressed(e -> {
            if(e.getButton() == MouseButton.PRIMARY)
                out.println("LEFT"); 
            if(e.getButton() == MouseButton.SECONDARY)
                out.println("RIGHT");      
            if(e.getButton() == MouseButton.MIDDLE)
                out.println("MIDDLE");    
            if(e.getButton() == MouseButton.NONE)
                out.println("OTHER");  
            // How read explorer buttons?  
            out.println("click");
        });

        Scene scene = new Scene(pane, 300, 100);
        stage.setTitle("Demo");
        stage.setScene(scene);
        stage.show();
    }
}

Just for the example, I would like to record that the advance and retreat buttons were activated. The only interaction I can achieve at this point is left, right and middle clicks. Pressing the forward and back buttons on the mouse doesn't even register the click print.

There was this post for Javascript: JS special mouse buttons, but it wasn't useful for my purposes.

Since JavaFX 12, the forward and back buttons on the mouse are recognized, so you can do:

pane.setOnMousePressed(e -> {
    if(e.getButton() == MouseButton.PRIMARY)
        out.println("LEFT");
    if(e.getButton() == MouseButton.SECONDARY)
        out.println("RIGHT");
    if(e.getButton() == MouseButton.MIDDLE)
        out.println("MIDDLE");
    if(e.getButton() == MouseButton.BACK)
        out.println("BACK");
    if(e.getButton() == MouseButton.FORWARD)
        out.println("FORWARD");
    if(e.getButton() == MouseButton.NONE)
        out.println("NONE");  
    out.println("click");
});
