java中JTable表格实现添加图片的渲染

Posted 2021-09-04 Recently 祝祝

一：自定义类MyCellRender实现接口TableCellRenderer，重写组件方法

import java.awt.Component;

import javax.swing.Icon;
import javax.swing.JLabel;
import javax.swing.JTable;
import javax.swing.table.TableCellRenderer;

import com.uplooking.util.UtilTest;

public class MyCellRender implements TableCellRenderer {

	@Override
	public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus,
			int row, int column) {
		if (value == null) {
			JLabel lbl = new JLabel("未有添加");
			lbl.setHorizontalAlignment(JLabel.CENTER);
			lbl.setVerticalAlignment(JLabel.BOTTOM);
			return lbl;
		}
		Icon icon = UtilTest.getIcon(value.toString());
		JLabel photo = new JLabel(icon);
		return photo;
	}

}

二：UTilTest类中getIcon方法获取对象

public static Icon getIcon(String name) {
	Image image = getImage(name);
	Icon icon =new ImageIcon(image);
	return icon;
}

三：UTilTest类中getImage方法获取图片

public static Image getImage(String name) {
	URL url = UtilTest.class.getClassLoader()
			.getResource("images/" +name);
	Image image  =Toolkit.getDefaultToolkit().getImage(url);
	return image;
}

四：在JTable对象实现：
