I have a JTable created from Vector. How can the JTable be refreshed to display new data that is added to the Vector?

推荐答案

当对TableModel进行更改时，您的JTable应该会自动更新.我在这里取得了飞跃，但是我猜想您不是在使用自己的TableModel，而是在Vector中调用了JTable构造函数.在这种情况下，您可以钩住TableModel并将其转换为DefaultTableModel，然后调用其通知方法之一以让JTable知道更改，例如:

Your JTable should update automatically when a change to the TableModel happens. I'm taking a leap here but I'm guessing that you're not using your own TableModel and just called the JTable constructor with your Vector. In this case you can get a hook on the TableModel and cast it to a DefaultTableModel and then call one its notification methods to let the JTable know of a change, something like:

DefaultTableModel model = (DefaultTableModel)table.getModel();
model.fireTableChanged(new TableModelEvent(........));

我会真的建议使用您自己的TableModel，除非这是非常琐碎的事情，但事实是您正在更新数据表明并非如此.

What I would really recommend is using your own TableModel unless this is something very trivial, but the fact you're updating the data indicates it's not.

在使用表格，尤其是监听数据更改的部分.

这似乎需要更多的准备工作，但从长远来看，它将为您省去很多头痛，并且是正确的方法
