当我尝试在JTable中插入生成的netbeans时遇到了很多困难。
捕获我的JTable的自定义代码。
所以我如何准确地将Image设置为我的类代码中的jtable。

您需要覆盖getColumnClass()
方法,以便表格可以选择合适的渲染器。简单的例子:
import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;
public class TableIcon extends JFrame
{
public TableIcon()
{
ImageIcon aboutIcon = new ImageIcon("about16.gif");
ImageIcon addIcon = new ImageIcon("add16.gif");
ImageIcon copyIcon = new ImageIcon("copy16.gif");
String[] columnNames = {"Picture", "Description"};
Object[][] data =
{
{aboutIcon, "About"},
{addIcon, "Add"},
{copyIcon, "Copy"},
};
DefaultTableModel model = new DefaultTableModel(data, columnNames);
JTable table = new JTable( model )
{
// Returning the Class of each column will allow different
// renderers to be used based on Class
public Class getColumnClass(int column)
{
return (column == 0) ? Icon.class : Object.class;
}
};
table.setPreferredScrollableViewportSize(table.getPreferredSize());
JScrollPane scrollPane = new JScrollPane( table );
getContentPane().add( scrollPane );
}
public static void main(String[] args)
{
TableIcon frame = new TableIcon();
frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
frame.pack();
frame.setVisible(true);
}
}
