将右键单击菜单添加到SWT树中的treeitem

只需使用

tree.setMenu(Menu)

你去了：

public static void main(String[] args){    Display display = Display.getDefault();    final Shell shell = new Shell(display);    shell.setText("StackOverflow");    shell.setLayout(new FillLayout());    final Tree tree = new Tree(shell, SWT.NONE);    for(int i = 0; i < 10; i++)    {        TreeItem item = new TreeItem(tree, SWT.NONE);        item.setText("Parent " + i);        for(int j = 0; j < 3; j++)        { TreeItem child = new TreeItem(item, SWT.NONE); child.setText("Child " + i + " " + j);        }    }    final Menu menu = new Menu(tree);    tree.setMenu(menu);    menu.addMenuListener(new MenuAdapter()    {        public void menuShown(MenuEvent e)        { MenuItem[] items = menu.getItems(); for (int i = 0; i < items.length; i++) {     items[i].dispose(); } MenuItem newItem = new MenuItem(menu, SWT.NONE); newItem.setText("Menu for " + tree.getSelection()[0].getText());        }    });    shell.pack();    shell.open();    while (!shell.isDisposed())    {        if (!display.readAndDispatch()) display.sleep();    }    display.dispose();}
