JTable中某列加入JCombobox，当移动到jcombobox后，用上下键选择jcombobox中内容的时候，却跳入jtable的下一行了，求解决方法
目前已经实现：用回车键替换掉了Tab键，按回车或者光标上下左右键就可以按顺序选择单元格，且同时进入当前选择单元格的编辑状态
想实现的是：当移动到jcombobox后，用上下键选择内容后，回车键，然后跳到紧挨着的“工作天数”单元格

如图所示

按下 “下键”却蹦到下一行了


我的想法是：当移动到这一列时，暂时将JTable默认的按键事件移除，只执行JCombobox，然后跳到下一单元格时再恢复按键事件……呵呵，无奈自己写不出来相关代码……愁了好几天了，查阅jdk以及浏览很多网页未果

直接给JCombobox的元素加消息 直接设置对应行的'类别'设置 ，

comboBox.addItemListener(new ItemListener(){

			public void itemStateChanged(ItemEvent arg0) {
				// TODO 自动生成方法存根
				//再次加入处理函数 比如设置某个table项的内容

			}
			
		});

谢谢，我先去试试……

总感觉还是有点迷糊

我把代码发上来，朋友帮我看看，谢谢


public class TableTest {

我不会像1楼那样发代码……

找不到该怎样把代码发成那样子

[musiclee]

我把你代码试了下

jt.addKeyListener(new KeyAdapter() {
			public void keyReleased(KeyEvent e) {
				if (e.getKeyCode() == KeyEvent.VK_ENTER
						|| e.getKeyCode() == KeyEvent.VK_UP
						|| e.getKeyCode() == KeyEvent.VK_DOWN
						|| e.getKeyCode() == KeyEvent.VK_LEFT
						|| e.getKeyCode() == KeyEvent.VK_RIGHT) {
					JTable t = (JTable) e.getSource();
					int row, col;
					row = t.getSelectedRow();
					col = t.getSelectedColumn();
					t.editCellAt(row, col);
					if (col == 0) {  //这里改成0  就没有楼主说的情况了
						jcbtype.setPopupVisible(true);

					} else {
						JTextField editor = ((JTextField) t.getCellEditor()
								.getTableCellEditorComponent(t,
										t.getValueAt(row, col), true, row, col));
						editor.selectAll();
					}

				}
			}
		});

[musiclee]

其实还是有点看不懂你的意思 你到底想要什么效果？

[MisterNil]

如果改成0的话，我这儿就一直报错了【Exception in thread "AWT-EventQueue-0" java.awt.IllegalComponentStateException: component must be showing on the screen to determine its location】

if（col == 1）{
jcbtype.setPopupVisible(true);
}这段代码：我的本意是当选择的列是第二列（也就是“类别”）的时候，JCombobox中的Item自动展开

我想要的效果就是：当用回车或者光标键移动到“类别”这一列时，JCombobox自动展开，然后再直接用光标键移动到JCombobox中的其中某一项，然后按回车选中（比如选中“班长”），同时光标跳入右边的单元格（“工作天数”），且“工作天数”这个单元格进入编辑状态。

愁死我了

大家帮我看看呀，谢谢

[MisterNil]

顶下……

谢谢
