将该项目添加到jlist后，从自动完成组合框中删除该项目
在这里我添加了一个名为glazedlists_java15-1.9.0.jar的jar文件
这是将字段添加到jpanel的代码
DefaultComboBoxModel dt=new DefaultComboBoxModel();
comboBook = new JComboBox(dt);
comboBook.addItemListener(this);
List<Book>books=ServiceFactory.getBookServiceImpl().findAllBook();
Object[] elementBook = new Object[books.size()];
int i=0;
for(Book b:books){
elementBook[i]=b.getCallNo();
// dt.addElement(elementBook[i]);
i++;
}
AutoCompleteSupport.install(comboBook, GlazedLists.eventListOf(elementBook));
comboBook.setBounds(232, 151, 184, 22);
issuePanel.add(comboBook);
btnAdd = new JButton("+");
btnAdd.addActionListener(this);
btnAdd.setBounds(427, 151, 56, 23);
issuePanel.add(btnAdd);
JScrollPane scrollPane = new JScrollPane();
scrollPane.setBounds(232, 184, 184, 107);
issuePanel.add(scrollPane);
v=new Vector<String>();
listBooks = new JList(v);
scrollPane.setViewportView(listBooks);
btnRemove = new JButton("-");
btnRemove.addActionListener(this);
btnRemove.setBounds(427, 185, 56, 23);
issuePanel.add(btnRemove);
动作在这里执行了代码。
public void actionPerformed(ActionEvent e) {
if(e.getSource()==btnAdd){
DefaultComboBoxModel dcm = (DefaultComboBoxModel) comboBook.getModel();
dcm.removeElementAt(index);
// Add what the user types in JTextField jf, to the vector
v.add(selectedBook);
// Now set the updated vector to JList jl
listBooks.setListData(v);
// Make the button disabled
jb.setEnabled(false);
}
else if(e.getSource()==btnRemove){
// Remove the selected item
v.remove(listBooks.getSelectedValue());
// Now set the updated vector (updated items)
listBooks.setListData(v);
}
该图显示了从组合框向jlist添加项目，然后从组合框隐藏或删除该项目。
如果你们知道这件事，请在这里分享答案。＆谢谢！！！
最佳答案
从我的描述和代码中可以看出，您只是使用GlazedLists便捷方法来设置初始自动完成组件，而没有使用GlazedLists的基本组成部分将各种元素缝合在一起：EventLists。
当然-您已经从EventList派生了一个来填充自动完成安装，但是GlazedLists确实希望您能够利用EventList在整个过程中而不是在快速交换期间保存对象。像JComboBox和JList这样的纯Java Swing组件会迫使您沿着数组和向量的路线前进，但是如果坚持使用各种EventList实现作为基本集合类，则GlazedLists将提供许多帮助程序类。它具有用于combobox和jlist模型的类，以及选择模型类，这些类方便地将EventLists和Swing组件链接在一起，一旦走这条路，您就可以真正简化代码。
这是我想达到的目标的非常原始的例子。我认为代码说明了一切，而不是我再随意讨论。注意：我使用了GlazedLists 1.8。
