working with images
hi,
i've placed an image in the frame and I've written mouse movement. it is ok for single image. but if i use multiple images and i need to select particular image and move it to a position. i don wan to work with cursor. i want to work with individual component. please review my code below to get clear idea
import java.awt.*;
import javax.swing.*;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.MouseEvent;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.event.MouseInputAdapter;
publicclass MoveImageextends JFrame
{
privatefinalstaticint SQUARE_EDGE_LENGTH = 40;
private Image image;
String img1="icons/Capacitance.gif";
private JPanel panel;
privateint xPos;
privateint yPos;
public MoveImage(String s)
{
super(s);
setSize(new Dimension(1022, 725));
this.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
xPos = 50;
yPos = 50;
this.setVisible(true);
Toolkit toolkit = Toolkit.getDefaultToolkit();
image = toolkit.getImage(img1);
MediaTracker mediaTracker =new MediaTracker(this);
mediaTracker.addImage(image, 0);
try
{
mediaTracker.waitForID(0);
}catch (InterruptedException ie){System.err.println(ie);}
panel =new JPanel()
{
publicvoid paint(Graphics g)
{
super.paintComponent(g);
g.setColor(Color.RED);
g.drawImage(image, xPos-(SQUARE_EDGE_LENGTH/2), yPos-(SQUARE_EDGE_LENGTH/2),null);
//g.drawImage(image, xPos-(SQUARE_EDGE_LENGTH/2), yPos-(SQUARE_EDGE_LENGTH/2), null);
}
};
MouseInputAdapter mia =new MouseInputAdapter()
{
publicvoid mousePressed(MouseEvent e)
{
xPos = e.getX();
yPos = e.getY();
panel.repaint();
}
publicvoid mouseDragged(MouseEvent e)
{
xPos = e.getX();
yPos = e.getY();
panel.repaint();
}
};
add(panel);
panel.addMouseListener(mia);
panel.addMouseMotionListener(mia);
}
publicstaticvoid main(String args[])
{
new MoveImage("Move my Image");
}
}
