java下拉树_JAVASwing中怎么把树添加到下拉框中privateJPanelcreateIterationPane(){JPanelpane=newJPanel();(,newJLabel("迭代"));JComboBoxiterationBox=newJComboBox();private JPanel createIterationPane(){JPanel pane = new JPanel();(,new JLabel("迭代"));JComboBox iterationBox = new JComboBox();ferredSize(new Dimension(200,20));table(true);//定义⼏个初始节点DefaultMutableTreeNode parentNode = new DefaultMutableTreeNode("");DefaultMutableTreeNode iteration1 = new DefaultMutableTreeNode("迭代1");DefaultMutableTreeNode iteration2 = new DefaultMutableTreeNode("迭代2");DefaultMutableTreeNode iteration3 = new DefaultMutableTreeNode("迭代3");//通过add⽅法建⽴树节点之间的⽗⼦关系(iteration1);(iteration2);(iteration3);//以根节点创建树tree = new JTree(parentNode);//设置是否显⽰根节点的“展开/折叠”图标,默认是wsRootHandles(true);//设置节点是否可见,默认是tVisible(true);m(parentNode);//添加到下拉框(iterationBox);return pane;}展开
