时间日期管理器模拟问题

[bakeloar]

别人提出来的问题，我解决了一部分，目前还有两问题没解决
1、在日期的那个JComboBox改变时，选中焦点的日期没了
2、空白空格应禁止选中
还有两个问题没有解决

很遗憾没达到楼主的要求第1问还没解决
第2问我是通过将其选中并该为白色的简单代替

		tab.addMouseListener(new MouseAdapter() {
			public void mouseReleased(MouseEvent e) {
				int i = Integer.valueOf((tab.getValueAt(tab.getSelectedRow(),
						tab.getSelectedColumn()).toString()) + 0);
				System.out.println(i);
				if (i == 0) {
					tab.setSelectionBackground(Color.white);
					tab.setUpdateSelectionOnSort(true);
				} else
				// if(tab.getValueAt(tab.getSelectedRow(),
				// tab.getSelectedColumn()).toString().equals("")){
				// tab.setSelectionBackground(Color.white);
				// }
				// if (!tab.getValueAt(tab.getSelectedRow(),
				// tab.getSelectedColumn()).toString().equals(""))
				{
					cmb2.setSelectedIndex(Integer.parseInt(tab.getValueAt(
						tab.getSelectedRow(), tab.getSelectedColumn())
							.toString()) - 1);
					tab.setSelectionBackground(Color.blue);
				}
			}
		});

第一个问题参数错误，应该为
tab.changeSelection(weekOfMonth - 1, dateOfWeek - 1, false, false);

[白云冰河]

isCellSelected是JTable的方法，重写之后小单元格选是可以选，但是不会变色

[bakeloar]

第一个问题解决，如楼上所说的把参数改成tab.changeSelection(weekOfMonth - 1, dateOfWeek - 1, false, false);就搞定

[白云冰河]

第二个问题，自己重写jtable的isCellSelected方法

[bakeloar]

好象没有什么效果
public boolean isCellSelected(int row,
int column){
return false;
}
我把所有的都设有false还是可以选中呀


请问下isCellSelected是在DefaultTableModel下吗？
