JTable to set up your own drawing and editor

Then small series on one , a unit of this small series tried to add Gerry Jbable own compiler and renderer

Write your own renderer first need to expand DefaultTableCellRenderer rewrite getTableCellRendererComponent method

在这里插入代码片
import java.awt.Component;
public class me extends DefaultTableCellRenderer{
public  Component getTableCellRendererComponent(JTable table,Object value,boolean isSelected,boolean isFocused,int row,int column) {
	Image i=((ImageIcon)value).getImage();
	ImageViewer m=new ImageViewer(i);
	return m;
}
}

Xiao Bian will put his image in the picture viewer

在这里插入代码片

import java.awt.Component;
import java.awt.Graphics;
import java.awt.Image;

import javax.swing.JPanel;

public class ImageViewer extends JPanel {
	Image i;
	public ImageViewer(Image i) {
		this.i=i;
	}
	public void paintComponent(Graphics g) {
		super.paintComponent(g);
		g.drawImage(i, 0, 0, getWidth(), getHeight(), this);
	}
}

Then expand your table model, the one spoken

在这里插入代码片
import javax.swing.ImageIcon;
import javax.swing.table.DefaultTableModel;

public class my extends DefaultTableModel{

public my(Object [][]a,Object[]b) {
	super(a,b);
}
public Class getColumnClass (int c) {
	return getValueAt(0,c).getClass();
}
public boolean isCellEditable(int a,int b) {
	return getColumnClass(b)!=ImageIcon.class;
}
}
