JTable中的JComboBox [英] JComboBox in JTable

问题描述

我在JTable的第3和第4列中有一个JComboBox，但我不知道如何获取其项目...问题不是获取项目的方法，而是演员

I've a JComboBox in 3rd and 4th column of a JTable but I don't know how to get its items...the problem isn't the method to get items but the cast

JComboBox combo=(JComboBox) jTable1.getColumnModel().getColumn(3).getCellEditor();

你能帮我吗?

推荐答案

JComboBox包装在CellEditor中.您必须检索包装的组件，例如在使用DefaultCellEditor时:

The JComboBox is wrapped in a CellEditor. You must retrieve the wrapped component, for example when using DefaultCellEditor:

DefaultCellEditor editor = (DefaultCellEditor)table.getColumnModel().getColumn(3).getCellEditor();
JComboBox combo = (JComboBox)editor.getComponent();
