Java applets

Posted: Jul 16, 2004 9:26 PM

I want to write an applet that will draw a wide rectangle on which two small rectagles which act as sliders will slide on the wider rectangle as i drag the mouse. I have written the applet for one slider to work perfectly alright i want the other rectangle also to work so can anybody help me please. The code is as follows which is saved in Events1.java.



<font color="navy"><b>import</b></font> java.awt.*;<br>
<font color="navy"><b>import</b></font>  java.awt.event.*;<br>
<font color="navy"><b>import</b></font> java.applet.*;<br>
<br><br><br> 
<font color="navy"><b>public class </b></font>Events1 
<font color="navy"><b>extends</b></font>  
<font color="navy"><b>Applet</b></font>
     <font color="navy"><b>implements</b></font> MouseMotionListener {<br>

 int mouseX =100,mouseY=100,mouseX2=496,mouseY2=100;
<br><br>
<font color="navy"><b>public void </b></font>init() {<br>

   addMouseMotionListener(this);<br>
}<br>

<br><br>

< font color="navy"><b>public void </b></font> mouseDragged(MouseEvent me) {<br>


     if((me.getX() >= 100) && (me.getX() <= 500)) {<br>

       if(me.getY() == 100) {<br>
               mouseX = me.getX();<br>
               mouseY = me.getY();<br>

               repaint();<br>
         }<br>
    }<br>

}<br><br><br>
<font color="navy"><b>public void </b></font>  mouseMoved(MouseEvent me) {<br>

     showStatus("Moving mouse at " + me.getX() + "," + me.getY());<br>
}<br><br><br>
<font color="navy"><b> public void </b></font> paint(Graphics g) {<br>
               g.drawRect(100,99,401,16);<br>
               g.setColor(Color.red);<br>
               g.fillRect(100,100,400,15);<br>
               g.setColor(Color.green);<br>
               g.fillRect(100,100,mouseX-100,15);<br>
               g.setColor(Color.yellow);<br>
               g.fillRect(mouseX2,mouseY,5,15);<br>
               g.setColor(Color.blue);<br>
               g.fillRect(mouseX,mouseY,5,15);<br>
   }<br>            

}<br>

The corresponding HTML code is saved in k1.html:



<html><br>&lt;applet code=Events1.class width=400 height=300&gt;<br>&lt;/applet&gt;<br>[code]
