How to use timer to do the movement an object

You can move the object inside the time handler function.
When user speeds up the movement, you'll kill the current timer and set a new one (with the same ID) that will have a shorten timeout value. This inside the handler for the speed control.

In the 1st place,
b4 i proceed to speed up the timer,

may i noe how to write the function to redraw the rect(lift)
in a new location and repaint()?

Can give some code?

Thanx.

How do you draw it in the first place?

Do you wan me to send u my code?

Yep, some code.
I mean, do you use GDI functions?

Do u mind to give me ur email address?
I send my code to u...
Is very simple coding....

No email.
The idea is to remove the rect from the first location and draw it to the next one.

import java.awt.*;
import javax.swing.*;


/*** Create a rectangle box as the elevator*****/
class RectPanel extends JPanel
{
public int x, initialY, y;
protected void paintComponent(Graphics g)
{
super.paintComponent(g);      

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
int screenWidth = screenSize.width;
int screenHeight = screenSize.height;
            
x = getWidth()/2-20;
initialY = getWidth()/2-20;
            
//set new color
g.setColor(Color.black);
                        
//draw a rectangle
g.drawRect(x,y,40,23);
g.fillRect(x,y,40,23);
            
}

public void setNewY()
{
      y = y - 10;
      repaint();
}
}

Above are my code for the rectangle. The rectangle currently is static and cannot move.

My problem is how to remove it and redraw?

Thanx
