java - MouseWheelListener block 滚动

Question

    JEditorPane.addMouseWheelListener(new MouseWheelListener() {
        public void mouseWheelMoved(MouseWheelEvent e) {
        }
    });

当我添加这些行时 - 在 JEditorPane 中滚动停止工作。如何治愈？

您应该发布更多代码以获得更好的帮助。然而，这个简单的演示对我来说效果很好(即在将 MouseWheelListener 添加到 JScrollPane 后滚动仍然有效)。

import java.awt.event.MouseWheelEvent;
import java.awt.event.MouseWheelListener;

import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JScrollPane;

public class Frame
{
    public static void main( String[] args )
    {
        JFrame frame = new JFrame( );
        JEditorPane pane = new JEditorPane( );

        String t = "";
        for ( int i = 0 ; i < 10000 ; i++ ) t += "t";

        pane.setText( t );

        JScrollPane scroll = new JScrollPane( pane );

        scroll.addMouseWheelListener( new MouseWheelListener( )
        {
            @Override
            public void mouseWheelMoved( MouseWheelEvent e )
            {
                System.out.println( "Scroll" );
            }
        });

        frame.add( scroll );
        frame.setSize( 400, 400 );
        frame.setVisible( true );
    }
}
