如何使用swt.TabItem添加关闭按钮？

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.MouseAdapter;
import org.eclipse.swt.events.MouseEvent;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.graphics.Point;
import org.eclipse.swt.graphics.Rectangle;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.TabFolder;
import org.eclipse.swt.widgets.TabItem;

public class CustomTabFolder extends TabFolder {
    public CustomTabFolder(Composite parent, int style) {
        super(parent, style);
        addMouseListener(new MouseAdapter() {
            @Override
            public void mouseUp(MouseEvent e) {
                TabItem tabItem = getTabItem(new Point(e.x, e.y));
                if (tabItem != null) {
                    Rectangle closeButtonBounds = getCloseButtonBounds(tabItem);
                    if (closeButtonBounds.contains(e.x, e.y)) {
                        closeTab(tabItem);
                    }
                }
            }
        });
    }

    private void closeTab(TabItem tabItem) {
        if (tabItem != null) {
            tabItem.dispose();
        }
    }

    private Rectangle getCloseButtonBounds(TabItem tabItem) {
        // 计算关闭按钮的位置和大小
        Rectangle tabBounds = tabItem.getBounds();
        int closeButtonWidth = 16;
        int closeButtonHeight = 16;
        int closeButtonX = tabBounds.x + tabBounds.width - closeButtonWidth - 5;
        int closeButtonY = tabBounds.y + (tabBounds.height - closeButtonHeight) / 2;
        return new Rectangle(closeButtonX, closeButtonY, closeButtonWidth, closeButtonHeight);
    }
}

CustomTabFolder tabFolder = new CustomTabFolder(shell, SWT.TOP);

TabItem tabItem1 = new TabItem(tabFolder, SWT.NONE);
tabItem1.setText("Tab 1");

TabItem tabItem2 = new TabItem(tabFolder, SWT.NONE);
tabItem2.setText("Tab 2");

// 添加其他TabItem
