Question

ARRRRGH! pls Help!
import java.applet.*;
import java.awt.*;
public class Project extends Applet {
private int last_x, last_y;
public boolean mouseDown(Event e, int x, int y)
last_x = x; last_y = y;
return true;
public boolean mouseDrag(Event e, int x, int y)
g.drawLine(last_x, last_y, x, y);
last_x = x;
last_y = y;
return true;
I get a error on compile time where a arrow points at the g in the
g.drawLine method, and it says "Project.java uses or overrides a depricated api"
If you can, copy and paste the code and fix what you can, what I want to do is make lines useing the mouse

Answer 1

implement the MouseListener and MouseMotionListener:
public class Project extends Applet
                     implements MouseListener, MouseMotionListenerwhen you implement an interface though, you need to define each of the functions in that interface. Even if you aren't particularly interested in some of the methods, you must atleast leave them blank (unless you use an adapter):
MouseListener methods:
void mouseClicked(MouseEvent e)
Invoked when the mouse button has been clicked (pressed and released) on a component.
void mouseEntered(MouseEvent e)
Invoked when the mouse enters a component.
void mouseExited(MouseEvent e)
Invoked when the mouse exits a component.
void mousePressed(MouseEvent e)
Invoked when a mouse button has been pressed on a component.
void mouseReleased(MouseEvent e)
Invoked when a mouse button has been released on a component.
MouseMotionListener methods:
void mouseDragged(MouseEvent e)
Invoked when a mouse button is pressed on a component and then dragged.
void mouseMoved(MouseEvent e)
Invoked when the mouse button has been moved on a component (with no buttons down).
